Re: Choosing among multiple intra-area ASBR routers [7:5416]
No problem. I don't have that reference but let me try to explain. I've had a long day and am beat - this is a quick response. The book description you describe and quote sounds correct. The lowest cost route will be prefered when inter-area routes are used. If the same route exists but is an intra-area route then that will be used over the inter-area route. For intra-area routes lowest cost route is prefered as well. In the example you gave, the route you have listed is an External type 2 route which is neither intra-area or inter-area so it has different rules. I think you may be getting yourself confused. Set up a lab with no ASBR's/redistribution like below. e0---R1---e1 | | R2---e2R3 R1 e0 and e1 are in area 0. R2 e0 and R3 e1 is in area 0. R2 and R3 e2 is in area 1. R1 and R2 link, set cost to 10. R1 and R3 link, set cost to 10. R2 and R3 link, set cost to 300. Put some loopbacks on R2 and R3 and put them in area 1 and put some in area 1. Look at your OSPF database after everything has come up, etc. You should see that to get R2's area 1 loopback from a Area 1 R3 address it will go over e2 instead of going through area 0. This is because intra-area routes are prefered. Now, if you were to ping from a network in area 0 on R3 then it will go through R1 then to R2 because it is inter-area. --- Jaeheon Yoo wrote: Hi, Erick Thanks for your kind reply again. But it is a different story. I guess I know what you're trying to say. Have you really read the page 175 yourself. If you read it, you would know what I'm curious about. This is about multiple intra-area paths to ASBR. Please refer to OSPF Complete Implementation, p.223 It says that: ... , paths through nonbackbone areas area preferred over paths through the backbone area 0.0.0.0. When multiple preferred paths are available, the one with the smallest cost is used. But in Cisco routers with IOS 12.0, we have different result. it seems to conform to rfc 1583. Hope somebody can clarify this for me. Regards, Jaeheon On 22 May 2001 08:55:46 -0400, [EMAIL PROTECTED] (Erick B.) wrote: Did you get my response to your original post? The route on r2 is a E2 route so it is not intra-area, but a externally learned route so different rules come into play. With external routes, there is a forwarding address (next-hop value) of the lowest cost route to that destination. Look at the RFC again - pages 23-25 or so, the section dealing with external routes. They explain it there well and have an example. --- Jaeheon Yoo wrote: Hi, all According to rfc2328. p.175, when we have multiple intra-area paths to ASBR,a intra-area path using non-backbone area should be chosen over one using backbone area.

Funny problems with debug [7:5527]
When I use debug in my lab, sometimes the router just stops debugging. For example, it may be debugging fine for awhile. Then, all of a sudden, it will just stop debugging. The router is still alive, as I am perfectly able to type in commands, change things around, etc. It just no longer produces debug information. It's happened to me on both the console and telnet (and I have typed term mon about a billion times). I type show debug, and it shows that debugging is on. But there is no output. I even type debug all (it's not a production router), and still get no output which is ridiculous because I'm running a bunch of routing protocols on the router. Like I said, the router doesn't die after I type debug all (because it is very lightly loaded), as I am perfectly able to type in config commands and show commands. It just does not produce any debug output. Nor does clear logging help. The only thing that I have found that helps is to reboot the router. Then, I can put in some debug commands, and debug output will be created. And then of course, after some time, the router will just stop debugging, and I have to reboot it again. So, anybody know what is up with that? I am using 12.0(17).

Easy-Answer: The default gateway should be set to the router that services the maximum number of destinations in the minimum number of hops. I.e., If RouterA services a 30 location frame network, and RouterB only services a single t1, you would use RouterA as the Default gateway. Why? Because you would have the least number of hops for a maximum number of sites. Slightly-More-Difficult-but-better-answer: Both!

RE: how to enlarge Switching Backplane of 6509 [7:5487]
It's always fun to have one of these discussions, especially when I could be sleeping. This one seems to be turning into yet another of those what is truth? questions. When dealing with Cisco, it is sometimes difficult to tell. The following link would appear to say something other than what you have quoted. Granted, mine is a quick skim. But it does seem to state that one SFM card provides 256G and the other is for redundancy. http://www.cisco.com/warp/public/cc/pd/si/casi/ca6000/prodlit/c6sfm_ds.htm notice that later in the link, Cisco starts talking bout packets per second ( PPS ) If you add the MSFC card you get 30mpps and if you add the DCF card on top of that you get 100mpps. I bring this up because I had a conversation off line with someone about needing the MSFC and DCF in order to get the 256G backplane. Cisco's own configuration tool indicates no. The person with whom I was discussing this indicated he has done a lot of research and his finding was yes. My own reading tells me that if I were an EE I might actually understand the link a bit better, and perhaps it would make more sense. As is stands, I am perceiving it as a lot of double-talk. This next link is where you, Frank, may have gotten your quote about the failover. http://www.cisco.com/univercd/cc/td/doc/product/lan/cat6000/sft_6_1/configgd /swfab.htm#xtocid223541 I just opened NetformX, the configuration tool my boss paid a LOT of money for me to use in my design work.

For example, it may be debugging fine for awhile. Then, all of a sudden, it will just stop debugging. The router is still alive, as I am perfectly able to type in commands, change things around, etc. It just no longer produces debug information. It's happened to me on both the console and telnet (and I have typed term mon about a billion times). I type show debug, and it shows that debugging is on. But there is no output. I even type debug all (it's not a production router), and still get no output which is ridiculous because I'm running a bunch of routing protocols on the router. Like I said, the router doesn't die after I type debug all (because it is very lightly loaded), as I am perfectly able to type in config commands and show commands. It just does not produce any debug output. Nor does clear logging help. The only thing that I have found that helps is to reboot the router. Then, I can put in some debug commands, and debug output will be created. And then of course, after some time, the router will just stop debugging, and I have to reboot it again. So, anybody know what is up with that? I am using 12.0(17).

Re: share Ethernet [7:5368]
thanks for your reply is it possible for a unix server to have two gateways..? If it's Un*x, why not just run RouteD or GateD, and include your Un*x as another routing host? Rob./ - Original Message - From: Hire, Ejay To: Sent: Tuesday, May 22, 2001 9:05 PM Subject: RE: share Ethernet [7:5368] If I'm understanding you correctly, you have a server on the same Ethernet segment as two routers, and you want to know which one should be set as the default gateway for the server. Easy-Answer: The default gateway should be set to the router that services the maximum number of destinations in the minimum number of hops. I.e., If RouterA services a 30 location frame network, and RouterB only services a single t1, you would use RouterA as the Default gateway. Why? Because you would have the least number of hops for a maximum number of sites. Slightly-More-Difficult-but-better-answer: Both! Run HSRP on both routers, which will create a single virtual router that is maintained even if one of the routers fails.

Can I have a 2600 T-1 WIC bound to a Dialer interface? [7:5546]
Consider this. I have 2 2610's, each with a WIC-1DSU T-1 card in them. I have these T-1's connected back to back. I have tried putting IP addreses, using encap ppp, and everything works cool, exactly the way I would expect it to work. So I know the cards and the cable and all that are working fine. Now, I want to try to have the T-1 interfaces invoked via Dialer interfaces. Why? Because eventually I want to get 2 more of these T-1 cards, and install one in each (so each router has 2 of them) and then run ppp multilink where I bond the 2 T-1's together to form a 3 Mb pipe. But I just cannot do it. Specifically, I have tried various ways to get the Dialer interface to bond to the T-1's (Serial 0/0). It never works. For example, I create rotary groups. It doesn't work. Then I try dialer pools. It also doesn't work. Everything I have tried doesn't work. For example, if I try to use dialer pools, then the router demands a dialer string. So I give it a dialer string. The Dialer interface then apparently tries to dial this string, which of couse fails because in a back2back T-1, there is nothing to dial. So if I try a rotary group, somehow the dialer interface never properly seizes the T-1. Instead I get an error like this, whatever the heck it means: r1#ping 192.168.20.2 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 192.168.20.2, timeout is 2 seconds: .

But what can I say, it has never worked for me, not once. The only thing that can I can think of is that all those CCO examples use 2500's, whereas I got 2600's here. But it shouldn't matter (or should it?). So, has anybody (especially somebody with a 2600 with a T-1 WIC)ever successfully put a serial interface under a Dialer interface and gotten them to bond correctly ? If so, could you shoot me a config?

This one seems to be turning into yet another of those what is truth? questions. When dealing with Cisco, it is sometimes difficult to tell. The following link would appear to say something other than what you have quoted. Granted, mine is a quick skim. But it does seem to state that one SFM card provides 256G and the other is for redundancy. http://www.cisco.com/warp/public/cc/pd/si/casi/ca6000/prodlit/c6sfm_ds.htm notice that later in the link, Cisco starts talking bout packets per second ( PPS ) If you add the MSFC card you get 30mpps and if you add the DCF card on top of that you get 100mpps. I bring this up because I had a conversation off line with someone about needing the MSFC and DCF in order to get the 256G backplane. Cisco's own configuration tool indicates no. The person with whom I was discussing this indicated he has done a lot of research and his finding was yes. My own reading tells me that if I were an EE I might actually understand the link a bit better, and perhaps it would make more sense. As is stands, I am perceiving it as a lot of double-talk.

Books with product suggestions? [7:5568]
Hello! I was wondering if anyone had run across a book that recommends products to use in certain situations? There seems to be so many solutions, and modules that you can add to each product, that I am confused about when you would want to take one route over another. For example, say the situation calls for the multiplexing of a few T1s. The book might say you can do this with this series of routers, just adding this module, and following these procedures: And it might say, you can also accomplish this by attaching this sort of equipment to a serial interface; however, there are some drawbacks and here is what they are: (Those examples are completely made up, and I don't know what I'm talking about!) I would hope to find something like this in a design book of somekind, but I haven't even looked at any.

Re: Can I have a 2600 T-1 WIC bound to a Dialer interface? [7:5569]
The best way to do this is to use inverse multiplexing multilink PPP. See the link below and scroll almost to the bottom for a configuration example. http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/12cgcr/dial_ c/dcppp.htm It does't use dialer interfaces but does nice load balancing without killing the processor. no ip route cache is another alternative on both T1's but puts all packet in the process switched path and can really slam the router processor.

RE: how to reduce a broadcast on PC? [7:5517]
I respectfully disagree. The 40% number refers to ethernet utilization, not to percentage broadcasts. In other words, as a rule of thumb, if you are running 4mbs of traffic across your Ethernet, you are approaching saturation. In terms of percentage of network traffic that is broadcast, there is an old saw that if broadcasts exceed a certain percentage of your traffic, your networking trouble. All I can say is that in the brokerage firm where I worked, during market hours, broadcasts made up around 90% of our network traffic. How else do brokers get their quotes. The key here is understanding how your network is used. In my case, understanding the nature of the business and therefore the usage of the network, I could sleep well knowing that life was good. In the case of the gentleman below, having used the Fluke to determine that something is happening, the next step is to determine why. The Linux box is used for what besides syslog? Is it the creator or the receiver of those broadcasts, or the creator? As a syslog server, I would venture to guess it is a top receiver. If there is a high percentage of broadcast, what other servers are there? How are hosts configured? What protocols are in use? What time of day was this done?

This one seems to be turning into yet another of those what is truth? questions. When dealing with Cisco, it is sometimes difficult to tell. The following link would appear to say something other than what you have quoted. Granted, mine is a quick skim. But it does seem to state that one SFM card provides 256G and the other is for redundancy. http://www.cisco.com/warp/public/cc/pd/si/casi/ca6000/prodlit/c6sfm_ds.htm notice that later in the link, Cisco starts talking bout packets per second ( PPS ) If you add the MSFC card you get 30mpps and if you add the DCF card on top of that you get 100mpps. I bring this up because I had a conversation off line with someone about needing the MSFC and DCF in order to get the 256G backplane. Cisco's own configuration tool indicates no. The person with whom I was discussing this indicated he has done a lot of research and his finding was yes. My own reading tells me that if I were an EE I might actually understand the link a bit better, and perhaps it would make more sense. As is stands, I am perceiving it as a lot of double-talk.

Re: Cable Multiservice Operators [7:5246]
It appears he is suggesting OPEN ACCESS agreement whereas the customer is allowed to choose which company they want to get their news, email, and service from. The CMTS belongs to whichever cable company installed it. If they are utilizing Cisco GSRs and UBRs, they will most likely be using MPLS and VPN to accomplish this. I would check to see what the downstream and upstream are running. Big difference between QPSK, QAM 16 and QAM 64. They will not be overbuilding the CMTS to accomplish this. The service company brings in their connection to the HeadEnd (OC3, OC12 whatever). If your company wants to overbuilding the CMTS you are talking about alot of work and money. I do not know what cable company you are dealing with but I doubt they would just give away channels as they lose revenue with TV when doing so. You are taking a channel away both in the upstream and downstream. The billing will be the service provider's issues. The cable company will charge for the bandwidth utilized. (depending upon the agreement). As this is a shared network, I would check the numbers of homespassed per node. This can range from 75 to 3000. Cablelabs recommends 500 homes passed per node. I would also check the number of subscribers per Blade card on the UBR. Cisco recommends not to exceed 1000 customers per blade. The cablemodem receives the permission to come on line from a LDAP server and usually uses a 10.X.X.X IP address and the customer will receive an IP from the Whom The cable company or the service provider? This as well needs to be reviewed. I know that cable companies are striving to achieve QOS but right now it is best effort. In your readings I would recommend Michael Adams book OpenCable Architecture from CiscoPress. I would also look at the Service Level Agreement with the cable company you are dealing with. It is amazing what happens when they change the cable plant around and not tell you what they are doing. I hope this helps.

What do you mean the cable infrastructure is Cisco? Aren't you going to provide your own gear. Then you can combine/split the signal at the headend. What do you mean they are going to sell you a frequency range? You should have only one DOCSIS downstream QAM per physical plant, hence only one frequency is needed not a range. It should be a standard 6 MHz ntsc channel. Start at 555 MHz and count 6 MHz either way and these are your center frequencies. EX 549, 555, 561, 567 etc... Or if you are not in North America you probally run an 8 MHz carrier. Never worked with Euro-DOCSIS, but it aint much different. You will also need a frequency for the upstream somewhere between 5 and 42 MHz, look for something 30 MHz and above. This will give you the friendliest environment for running the wide-boy 3.2 Mhz in the upstream. DOCSIS is a shared medium, this PVC MPLS-VPN you are talking about are ATM technologies (I Think) you can't run them on a DOCSIS network, security is provided through BPI or BPI+. Physical seperation means a separate cable plant, a cable company is not going to overbuild on themself just to provide DOCSIS which runs on one of many frequencies. Can't do guaranteed service or QOS until DOCSIS 1.1. I would check into that first and make sure all your gear is 1.1 compliant or else no QOS or BPI+.

Re: could a bgp reflector also be a client? [7:5528]
you can do for sure, but I'd approach it with caution - your root route-reflectors, if you see what I mean, are going to get pretty heavily loaded if there is significant transience out there. Remember that R-Rs nedd to accept updates from all clients, and flood them out to all other neighbors (client or not). Imagine what would happen if you have a two-layer hierarchy of RRs, whereby the clients at the bottom pass on their updates to the mid-layer RRs, which in turn will pass on the updates to the top-layer RRs, which have to flood out the updates Another possibility would be that route flaps might become amplified - ie generate multiple withdraw/announce pairs which would propagate through the network, impacting any flap-damping that may be inplemented. What is normally done is to have a fully (iBGP - not neccesarily physical) meshed backbone, with a pair of RRs at each major location, with them feeding local RR clients from there. hth Andy - Original Message - From: Chuck Larrieu To: Sent: Wednesday, May 23, 2001 8:49 AM Subject: RE: could a bgp reflector also be a client?

A general rule of thumb is that no more than about 20% of your traffic should be broadcasts, although the real answer is it depends. The reason to avoid broadcasts is because they interrupt the CPU on every device in the broadcast domain. I wonder if this is still a problem with 1.7 GHz P4 processors!? ;-) If you attach your fluke to a switched port, be aware that you will only see broadcasts or frames address to that port, (unless you use SPAN). Sometimes we get fooled into worrying about broadcast traffic because we forget that we aren't seeing the non-broadcast traffic because of switch behavior. Troubleshooting used to be so much easier in the days of shared Ethernet. ;-) First give some thought as to whether this 14% problem is even worth troubleshooting. If it is, you might want to get a protocol analyzer so you can see what the Linux station is sending. Also check the configuration on the Linux server. What services is it configured to be running? Could it be running RIP and sending routing table broadcasts? What is this Linux machine supposed to be doing besides acting as a Syslog server? Regarding the rule that Ethernet utilization shouldn't exceed 40%, remember that it was based on testing in a non-production network with traffic patterns that had no resemblance to real-world networks. You need to know what's connected to the Ethernet and what the connected stations should be sending to know if the rule applies in your situation, which is unlikely. Check out this great paper by David Boggs, one of the creators of Ethernet called Measured Capacity of an Ethernet: Myths and Reality.

Re: IPX Eigrp redistributed into IPX RIP [7:5571]
For one thing, EIGRP imports IPX hop count as the external metric - the rest of the metric is the standard EIGRP metric (bw delay, etc.).

The number of Internet-connected devices is proliferating rapidly. Mobile phone deployment, for example, is expected to reach more than 1 billion worldwide by 2005, and the majority of those phones will be Web-enabled. The construction of the world's 2.5G and 3G wireless networks alone, at some point, will drive the need for a dramatic increase in the pool of public IP addresses. In addition, the emergence of Internet appliances and home networks, along with the ramp-up of Internet connectivity in populous countries such as China, Russia, and India, will soon be significant contributors to the surge in IP address consumption. To future-proof Service Providers' Internet infrastructures, Cisco has made IP Version 6 (IPv6), as specified by the Internet Engineering Task Force (IETF), available at no charge in its latest release of Cisco IOS(r) software for early adopters. Cisco is the first networking equipment vendor to implement IPv6 support across a wide array of routing platforms. TECHNOLOGY BACKGROUND IPv6 extends the address space in an IP packet from 32 bits to 128 bits. This accommodates a much greater number of bit combinations, out of which IP addresses numbering into the trillions can be constructed. Standards for 3G networks-packet-switched wireless networks of up to 2-Mbps speeds that will be rolling out over the next several years-for example, mandate the use of IPv6 protocols. In addition, the expected launch of an IPv6-compliant release of the Microsoft Windows operating system late this year will serve as yet another significant driver. Unlike with IPv4, Dynamic Host Control Protocol (DHCP) client software is not necessary for dynamically allocating available user IP addresses in an IPv6 access network. In addition, ongoing IETF IPv6 development work will enable Service Providers to automatically and remotely configure an IP address on a customer's router, DSL modem, or cable modem. This capability slashes the time and expense associated with configuring CPE on a customer-by-customer basis. There are several ways IPv6 can be deployed to peacefully co-exist with IPv4 infrastructures. One bullet-proof scenario has been used for years on the experimental 6Bone, a constantly growing international IPv6 test bed. This approach is to first deploy IPv6 in edge routers and tunnel IPv6 packets over IPv4 or Multiprotocol Label Switching (MPLS) backbones. This is a cost-effective option, in that existing IPv4/MPLS backbone services can be maintained while updating only part of the network, and existing IPv4 revenues are not put in jeopardy. CONFIGURATION CONSIDERATIONS IPv6 is available at no charge in Cisco IOS Release 12.2(1)T for the Cisco 800, 1400, 1600, 1700, 2500, 2600, 3600, 4500, 4700, 7100, 7200, and 7500 series routers, as well as the Cisco AS5300 and AS5400 universal access servers. To minimize the Service Provider learning curve, commands for configuring IPv6 in Cisco software are the same as those for IPv4.

Re: Multiple ISP Leased Line [7:5536]
Search the newsgroup on BPG, as this is the real solution to what you're trying to accomplish. You need to advertise your ISP1 provider space out ISP2 and get ISP1 to allow you to announce it more specifically than their larger netblock. I suggest Halabi's Internet Routing Architectures, 2nd Edition, if you're going to do it yourself. Otherwise, hire a consultant who knows BGP to get the job done right. http://www.bestwebbuys.com/books/compare/isbn/157870233X You can actually have DNS point to multiple IPs, but it's just a random chance (round-robin) as to which one someone will get. So if ISP1 fails, 50% of the people would still get the DNS for the IP for that ISP, and due to DNS caching, you can't just simple remove the DNS to solve it (2 days in the minimum requirement for DNS caching). -- Jason Roysdon, CCNP+Security/CCDP, MCSE, CNA, Network+, A+ List email: [EMAIL PROTECTED] Homepage: http://jason.artoo.net/ imran obaidullah wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...

Re: could a bgp reflector also be a client? [7:5528]
As Andy says, hierarchical route reflection is perfectly reasonable and used operationally, but needs to be approached with caution. The most basic configuration issue, of course, is that the different levels of clusters mst have cluster IDs. You definitely want to look at the most current route reflector RFC, http://www.ietf.org/rfc/rfc2796.txt which discusses some loop prevention issues -- there are nuances about, for example, intra-cluster to inter-cluster IGP metrics. you can do for sure, but I'd approach it with caution - your root route-reflectors, if you see what I mean, are going to get pretty heavily loaded if there is significant transience out there. Remember that R-Rs nedd to accept updates from all clients, and flood them out to all other neighbors (client or not). Imagine what would happen if you have a two-layer hierarchy of RRs, whereby the clients at the bottom pass on their updates to the mid-layer RRs, which in turn will pass on the updates to the top-layer RRs, which have to flood out the updates Another possibility would be that route flaps might become amplified - ie generate multiple withdraw/announce pairs which would propagate through the network, impacting any flap-damping that may be inplemented. http://www.ietf.org/internet-drafts/draft-ietf-idr-route-oscillation-00.txt What is normally done is to have a fully (iBGP - not neccesarily physical) meshed backbone, with a pair of RRs at each major location, with them feeding local RR clients from there. hth Andy Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=5609t=5528 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Re: IPv^ info from Cisco [7:5602]

It seems odd that in their first foray into IPv6 that they would exclude their own routing protocol of choice. John Think about it. Aren't the early adopters for v6 likely to be interested in multivendor interoperability?

Re: OT -- BGP scalability [7:5468]
Being in California, I get to see my UPSes tested a lot if I like it or not. In my limited global BGP experience, one problem is the limitations on Independent, Portable IP space. If ARIN is unwilling to assign less than a /20, then you're forced to use Provider non-Portable IP space. Furthermore, if you're multihoming you're more likely to use the additional IP space you get from each provider (it's much easier to get 1-3 class Cs up front from a new ISP then to go back to an existing ISP and get more). For this reason, we've got 7 /24s and one /23 from 3 different ISPs. If we could even get a /21 from ARIN it would make much more sense to me. Then, instead of announcing 8 different routes it'd be one single route. I haven't even begin to look into IPv6 yet, but this is one way IP allocation could be greatly enhanced: Right now netblocks are assigned to ISPs/customers in direct sequence (or even ISPs that sub-delegate them to customers in sequence). So if you only need one /24, you get only one, and in 6 mos. if you need more, you're going to get one that isn't anywhere near the other. But instead, if they kept large gaps between allocation for future growth, when an end customer needs more IP space, they're just assigned the next blocks and the bits in the mask grow (and from a global point of you, that'd be all you see, no extra blocks announced with an existing AS's growth, just a change in bit mask). Of course this isn't practical with IPv4, but I'm hoping that's how IPv6 is being allocated. Of course, you might say Why not just assign really big netblocks to everyone that wants them since the IP space is so big?. In short sight it might not be a bad idea, but that's the same sort of thinking that go us in trouble with classful assignments and entire class A blocks going to companies. Oh, I'm probably just rambling. Well, I'm sure of it, but perhaps I'm making some sense. Of course when you consider the lack of support for IPv6 thus far... I mean Cisco IOS doesn't even support it (yet). http://www.cisco.com/warp/public/732/Tech/ipv6/ http://www.totaltele.com/view.asp?articleID=39924Pub=TTcategoryid=626kw=c isco Looks like 12.2(1)T will, but many won't use non-General Release versions, so that puts it another quarter away in 12.3. -- Jason Roysdon, CCNP+Security/CCDP, MCSE, CNA, Network+, A+ List email: [EMAIL PROTECTED] Homepage: http://jason.artoo.net/ Howard C.

Priscilla wrote, in response to John Hardman, Well, you're preaching to the choir, but I have a couple comments in line nonetheless. A really technical discussion would require more knowledge of statistics, queuing theory, etc., than I have. But it can't hurt to discuss the issues at a high level also. In the phone industry, we can use Erlang and other obscure methods for calculating the amount of bandwidth needed based on an acceptable frequency of someone picking up the phone and not getting dial tone. Why can't we do something similar with networking? I suspect it's because network traffic is so different from phone traffic. We claim that network traffic is bursty, but it's not nearly as bursty as phone traffic. There's very little quiet time. Even if the user isn't doing something there's still overhead traffic, keepalives, routing table updates, etc. The consequences of not being able to send this overhead traffic can result in serious performance degradation. While Erlang C distributions can be of some use in estimating buffered data network device capacity, the statistical aspects get complex. The conventional wisdom was that packet interarrivals were exponential, but more recent research (e.g., by Will Leland at Telecordia) showed that fractal distributions were much more accurate. There's also the aspect that traffic in a routed system is actively affected by congestion and other feedback. A surprisingly large number of Internet packets are 40 to 48 bytes. These turn out to be TCP, and primarily HTTP, acknowledgements, possibly with some buffer padding beyond the essential 20 bytes of IP and 20 bytes of TCP. HTTP is _not_ bandwidth efficient, or address space efficient, but there's a lot of inertia in upgrading it. Now this begs the next question... do people need 99.999% uptime on the phone system or on their network? Keep in mind that 99.999% uptime equals to apx 1 minute of downtime per 30 days. And adding each additional nine adds a lot of cost. Also, adding redundancy in particular parts of the overall system doesn't necessarily make things better. Perhaps going

VoIP redudancy [7:5621]
VoIP requires a lot of redundancy, from my experience so far. Granted, each site has all it's voice and data trunks going to the same CO. For instance in a current install: 12 Small offices (10-20 phones): 4 voice trunks 2 backup BRIs (for extra voice trunks and/or backup data) Full/Fractional T1 to frame relay cloud Main site (80 phones): T1 PRI for voice w/DID T1 PRI for data (analog dialup users mainly, backup lines for remote BRIs) Multiple T1s to frame clouds If all local trunks at a branch are in use, the last line forwards to a DID on the PRI and forwards back internally to that site. If the frame goes down, we've got enough BRIs to still function (in a much more limited capacity, but the VoIP network has priority and won't go down, data will suffer but still work and is primarilly terminal/text based or Citrix clients). We purposely have a small number of trunks at each site (most sites originally had 6-10 trunks), but part of the goal here is to save money with less trunks and also do toll-bypass (this customer has suppliers/customers/sites all over California, Neveda and Oregon). Also there is the advantage of faster data paths when the dynamically allocated VoIP isn't in use. So far, it seems to work good (only 2 remote sites up so far, working out kinks with other items like Unity voicemail/faxing and just waiting on frame circuits to be upgraded). 3 remote sites will probably be brought up in the next month, so we'll see how well it all scales (shouldn't matter, the hardest was just getting it all working right with the first 2 remote sites). Even though it's not dynamic, if for instance one sites local telco was having analog trunk problems, we could block all calls from being routed out those trunks (which I guess you can do in a traditional PBX system, but you probably wouldn't be doing with key systems which would be going in these small offices). We're actually doing that for the second of two sites to keep the local trunks open for incoming calls as the local telco goofed on a date to have the trunks forward long distance, so if all 4 local trunks are in use the 5th+ caller get forwarded to the other 4 trunks no longer in use and get a disconnect message. -- Jason Roysdon, CCNP+Security/CCDP, MCSE, CNA, Network+, A+ List email: [EMAIL PROTECTED] Homepage: http://jason.artoo.net/ John Neiberger wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...

[Warning: Slightly OT] Actually, here at our corporate headquarters we have redundant fiber connections to separate telco central offices. The fiber links exit on opposite sides of the building to frustrate Backhoe Bob in case he tries to cut through them. These links carry two separate channelized DS-3s that carry our voice and data circuits. Theoretically, you could bomb one of the CO and we'd be just fine; both DS-3s would stay up and running without a hiccup. I hope we never have occasion to test this.

Re: Pix with 2 different ISPs [7:5349]
I believe you need a router on the outside to determine where the packets go. I can't think of how you could get the PIX to route based on source (there are not route-maps). All you can do is permit/deny based on source... A sort of load balancing that you could do for a server would be to bind two private IPs (each pointing to public IPs from the two different ISPs) and have DNS point to both public addresses. That would tend to load balance the incoming traffic without getting into BGP. On the external router, you would just use a route-map to determine based on source address which ISP to route back through. Mind you there is no redundancy here. You'll need BGP for that, and even then you might not get global redundancy. -- Jason Roysdon, CCNP+Security/CCDP, MCSE, CNA, Network+, A+ List email: [EMAIL PROTECTED] Homepage: http://jason.artoo.net/ Tai Ngo wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...

We have 2 Pix firewalls, one which is configured for active with both outside interfaces. The other pix is configured as standby. Will the Pix firewall be smart enough to know how to route traffic back out the network it came from? For example, if a user came into our website from 204.23.23.x , will the Pix know how to route the info back out that interface instead of through the 205.23.23.x network? My guess is it's not possible because when you look at the configuration on the Pix, to route info outside, you would use route 0.0.0.0 204.23.23.x 1 . Thanks!
