Re: ethernet is up, line protocol is down
NO you will not be able to ping it. You will not see it in the show ip route command. If you want to bring it up just for testing then you can enter the command "no keepalive" in the interface configuration mode to bring it up but do that for testing only and once its up you can ping it and also see it in the routing table.

According to CIT - this means layer 1 is up, but layer 2 is down (paraphrase) - what I need to know is the reprecussions of this - In other words, can I ping this interface ip address from within the router? Could I do a sh ip route on this ip address and at least try to see it? Obviously, I can't do it from another router across the interface, but I thought I'd be able to assign an ip address, ping it internally, and have it ready to go when we get something to plug into it.

Re: CIR and routing metric
RIP is totally out of the question because its metric is independent of the link bandwidth. OSPF, IGRP and EIGRP do use the link bandwidth while computing the routing metrics but then they use the bandwidth specified with the "bandwidth" command. You can say that CIR is not directly related to any routing protocol's metric. But it is advisable to configure the bandwidth to reflect the CIR of your link in order to enable the routing protocols to calculate metrics that correctly reflect the link cost.

Re: what does becn and fecn high value indicate?
the bandwidth command is just for informational purposes. Routing protocols that rely on link bandwidth for metric calculation ( like OSPF, IGRP, EIGRP ) use this parameter.

Of course you cannot control the FECN and BECN bits. What you can do though is adjust the manner in which your IP traffic negotiates moving from fast links to slower links (LAN to WAN etc). This is where the bandwidth command amongst others can be useful. For example, routing off a fast ethernet port across the router into one of its serial ports requires a slowing of traffic. Serial ports cannot handle anywhere near 100mb of traffic. There are a number of ways one can handle this; prioritizing, queueing and using the bandwidth parameter are a few that spring to mind.

Re: Obscure (?) questions
1) It depends. If you have RSRB configured then the virtual ring number must be the same on both the bridges whereas this virtual ring number can be different if you are using DLSW. 2) Yes you are right about the ARP requests. When a LEC receives an ARP request it forwards the request to the BUS using the multicast send VCC. The BUS then forwards the request to all the LECs through the multicast forward VCC. The LEC with the destination device attached will also receive this ARP request and will forward the request to all ports in the corresponding VLAN. The destination device will service the request and then the LEC will have to uni cast this reply back to the oriiginator. Here is where the LE_ARP_REQUEST is generated in order to map the MAC address of the source to a NSAP address. In short the IP ARP request is serviced by the BUS while the LE_ARP_REQUEST is serviced by the LES. Eventually a Data Direct VCC will be established between the two LECs. There are some other issues before the successfull establishment of a data direct vcc but i should rather not go into the details :) My recommendation is that if you need more insight into ATM LANE and other advanced switching concepts get a hold of Cisco LAN Switching by Kenedy Clark.

However, the question got me thinking, what about the RIF from PC-a to PC-b which is on a seperate token ring. The disparraging part is that the virtual ring on bridge 1 is 10 and the virtual ring on bridge 2 is 0x10 (or 16). My question is this -- doesn't the virutal ring number need to be the same among all bridges? Also, while going over ATM LANE, I began to wonder exactly how broadcasts are handled. I understand that the BUS is supposed to handle all broadcasts, and also that an LE_ARP request is maps MAC address to ATM addresses. That got me wondering how an IP ARP request is handled. Does the client send the ARP to the BUS, which then forwards it via its point-to-Multicast Forward vcc, or does the BUS just handle it on its own? Thanks, K - Kristopher B.

RE: BCRAN Loopback int
You define a loopback interface using the global configuration mode command: int loopback 0 It immediately creates a virtual interface which is by default in the up/up state. This interface does not depend on other things ( like keepalives, clocking, physical cable connectivity ) to remain in the up/up state and remains up as long as the router is up and running. Take OSPF for example. In order for OSPF to function properly it requires a Router ID which is the highest IP address of an active interface on the router. In case you have loopback interfaces configured then the highest ip address amongst those of the loopback interfaces will be chosen as the router ID. The advantage you get is that if the Router ID is the ip address of a physical interface and the interface goes down then the OSPF operation is interrupted. However, if the Router ID is that of a loopback interface then the OSPF operation will never get interrupted as long as the router itself does not go down and a router going down is very uncommon as compared to an interface going down. BGP is another routing protocol that makes use of this advantage of the loopback interface. I hope this clears up things a bit.

If the links are from different providers then you will have to go for BGP.

RE: Two WAN conn.
Running BGP if you have onlyone provider is not a big ask so the provider can be asked to do it. About advertising default routes, i was not referring to BGP. You see here in pakistan you can make the provdier do anything :) so i dont blame you for not seeing a provider advertise default routes. Come to pakistan and i will show u ;) About the router load balancing between two default routes; well i read it on CCO. I will confirm it after testing it too.

RE: ip route
Jason these statements will load balance and we are doing static routing here so other routing protocols running on the router will not effect the load balancing. Regarding the second point, the router will stop sending the traffic through 2.2.2.1 only if this static route is removed from the router's routing table.

RE: BGP/OSPF issue
I think you can use the BGP backdoor option to achieve this. -Original Message-From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Gabriel NickelSent: Wednesday, August 30, 2000 12:02 PMTo: [EMAIL PROTECTED]Subject: BGP/OSPF issue Hi folks, we got a problem involving BGP and OSPF here. Lets say we are an ISP (AS 1) with two routers (Router1, Router2)in different cities. They are both running OSPF (and IBGP) to exchange intra-AS routing information. Router2 is connected via BGP to an upstream provider (AS 2). Router1 has static entries for a large customer network (downstream). All operations are running well but if we traceroute from our Router 2 to the customer network the packets dont take the path via Router 1 but via our upstream provider (AS 2) which is suboptimal and not desirable. From my understanding the packets chose this path because of the eBGP administrative distance (20). Do we have to decrease the OSPF distance to 20? In addition static routing is not desirable (there would be too many networks to announce). Any input would be much appreciated, Gabriel
RE: UDP and Fragmentation
Actually fragmentation is a layer 3 issue. IP packets encapsulate both UDP and TCP and it is the IP datagram that can get fragmented. Thats why they have the fragmentation offset and identification fields in the IP header; to take care of the fragmented packets. TCP sequence numbers add a touch of reiliability to the TCP protocol by ensuring that the TCP segments are arrived in order. However, UDP is not reliable as it does not have any sequence numbers so if UDP segments do come out of order it is the responsibility of a higher layer to point that out. In short i think you are getting confused between segmentation and fragmentation. Segmentation occurs at layer 4 while fragmentation occurs at layer 3. IP handles all the fragmentation issues so be it TCP or UDP encapsulated in IP fragmentation doesnt care for that matter. Hope this clears things up.

Re: load balancing on Rip
you do not need any commands to setup load balancing. The router will automatically load balance between equal cost routes. However, by default the router will load balance upto four equal cost routes and if you need to load balance between paths that are greater in number than four then you need to configure the router to do so. You can confirm that the router is load balancing when you take a look at the routing table and you see multiple next hops for a particular destination. Or a more entertaining way might be to turn on debug ip packet for packets to that destination ( do not use this command unless you know what you are doing ) and then issue a ping to that destination. You should see the next hop changing for every echo request ( provided the router is configured for process switching ) -Original Message- From: Donald B Johnson Jr [EMAIL PROTECTED] To: Atif Awan [EMAIL PROTECTED]; Agnelo D'souza [EMAIL PROTECTED]; [EMAIL PROTECTED] [EMAIL PROTECTED] Date: Monday, August 28, 2000 7:24 PM Subject: Re: load balancing on Rip Could You show me the commands to load balance RIP please.

Re: what criteria does a access-list use when a there is a contradiction?
more specifically with the following: ip access-list 10 deny host 192.168.1.19 ip access-list 10 permit any ip access-group 10 in this will deny packets sourced from the host 192.168.1.19 and will allow the rest to pass through ... I was recently told that the last line overrides any previous command. According to the Transcender info, the most restrictive security would be taken. the last line is for applying the access-list to an interface and if you are talking about the line before this access group then that does permit everything but keep this thing in mind that access lists are always checked sequentially. If a match occurs at any line then the appropriate action is taken and the list is no longer traversed. So in this case packets with the source ip address of 192.168.1.19 will match the first line and get denied immediately. Others will not match the first line and will definitely match the second as it is meant to match every packet so will be permitted. How bout something as obvious as this: ip access-list 10 deny host 192.168.1.19 ip access-list 10 permit host 192.168.1.19 ip access-group 10 in this will disallow everything because there is an implicit deny all at the end of an access list. Although you are permitting host 192.168.1.19 in the second line but here also the sequential nature of the access list prevails; as a consequence the packets sourced by this host will be denied. hope this helps Regards Atif ___ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Re: accesslists outbounds?
they say that outbound access lists are less processor intensive because the router has only to process those packets destined for the destination you are trying to affect. When you apply it inbound then the router has to match each packet coming into that interface even though that packet might not be relevant to the access list. The scenario presented is just a simple one and in this case it does not matter where you place the access list but think of two more serial interfaces in addition to S3. if you apply the access list inbound then packets destined for S4 and S5 will also have to be processed through the list even though they have nothing to do with the S3 interface. So the conclusion is that "Outbound access lists are IN GENERAL less processor intensive than in bound access lists" ... remember IN GENERAL ... there can be exceptions Regards Atif -Original Message- From: Dale Holmes [EMAIL PROTECTED] To: [EMAIL PROTECTED] [EMAIL PROTECTED]; [EMAIL PROTECTED] [EMAIL PROTECTED] Date: Wednesday, August 23, 2000 8:04 PM Subject: Re: accesslists outbounds?

You have run a debug command on a customer router while investigating a performance problem, or perhaps a security issue, and you have caused the CPU to exceed 100% and the router has hung/crashed. 2. You have edited an ACL remotely and reapplied it only to find you have blocked all traffic including telnet from your desk and you are now locked out. 3. In both of the above scenarios you have made up some story for the Help Desk/1st Line Support and asked them to get the customer to reboot the router, claiming that "a reboot may help the performance problem . . blah . . blah" 4. In each of points 1 2 the customer in question is a major account that has threatened legal action against your company for failing to maintain SLAs, or to close the account altogether.

Re: 802.3 frame and full-duplex
In fact SD stands for start of frame delimiter. It is an essential component of the synchronization process alongwith the preamble. Regards Atif To: Stephen Ede [EMAIL PROTECTED]; [EMAIL PROTECTED] [EMAIL PROTECTED] Date: Sunday, July 30, 2000 9:30 AM Subject: Re: 802.3 frame and full-duplex Stephen, First, SD is the last octet of the preamble. You get 7 octets of 0x55 and the final octet is 0xD5 which is signaling the start of the Data Link frame, hence SD. On the switch question, if port A,B, and C are sending packets to port D I think that the output queue on D would accumulate the packets if the offered load is greater than the link's capacity. However, the queue is not infinite and eventually you will have to start dropping packets.

But what happens when 2 or 3 of these stations want to transmit to one particular station concurrently? Is the traffic buffered in the switch? Or is CSMA/CD still in effect, even in full duplex mode, where they will sense the wire and wait if busy? 2) In the diagram below of an 802.3 frame, what does the "SD" potion signify? | Preamble | SD | Dest.

ip header question
I was thinking that wouldnt it be better if the ip header had the destination ip address field before the source ip header field and the TCP header had the destination port field before the source port field. I am not sure what kinda performance effect willl it have but since at the Data link layer you have the destination address first ( because of obvious reasons ) shudnt u have the destination ip address before the source ip address for these obvious reasons too. its just a thought but i will definitely like some insight on it.

Re: interesting part 2
Yeah enabling directed-broadcast solved the problem for the Netbios forwarding but a day later when the DHCP lease time for some of the clients expired there were probs again ... No i am not running frame-relay .. i will try to get the configs but i can assure u that there is nothing too complex in those and on top of that i know some of the basics too :) .. rest assured there is no config mistake.. either this is an IOS issue or something else :) The thing is that i need to go to the client site myself to get a look at the debug traces .. till now iall i have said is after hearing it from a friend but iwill let u all know if there is some progress towards the solution.

With enabling directed broadcasts depending on your addressing range will work - only cuz you are not using WINS. If using WINS then all should have been fine -- *I think*. The MS stuff is starting to fade away... For the second problem - DHCP not working...I assume you are using Frame really. 1st off why in the world would you want to do DHCP across a wan? Might as well bridge everything. Second - are you using inverse arp or frame map statements? If frame map statements do you have the broadcast keyword? What do your helper addresses look like? You can make helper addresses the real IP of the DHCP server ya know. It doesn't have to be a broadcast - unless you need broadcasts for other protocols. Sanitize your configs and send them to the list or directly to me. It will help us all.

You have a Catalyst 5000 with several servers connected and you've decided to rearrange the port assignments. You disconnect one server in particular and move it to another port, then quickly discover that it now has no network connectivity. You attempt to access the network for a couple of minutes to no avail. In supreme frustration, you head to the break room for coffee and donuts. When you come back several minutes later you find that the server now has network connectivity and all is well, no problems.

I'm not exactly sure how this is done, but by your model I'm imagining that you have the subnet mask as 0.0.0.24 so that you can get all of the required numbers to be excepted. Actually I think the subnet mask should be 0.0.0.25. Because it lays out like this: (yours): 0.0.0.00011000, if you do it like this than the addresses bit places would not match up with the net mask. (with mine): 0.0.0.00011001, all of the addresses specified (.1, .9, .17, and .25) all will match up with the mask and be allowed through...I think ;) Don't get me wrong, you may be right and I could just be rambling without a cause here ;) After all, I'm just a rookie ;) Let me know if I'm wrong and I'm gonna stay tuned to find out the answer.

Re: OSPF !!!
Priority does not affect route selection; it is only for the DR election process in OSPF. Cost does affect route selection. OSPF determines the best route to a destination based upon the metric called cost. By default cost is calculated using the formula : Cost = 10exp8/ bandwidth of the interface ( i think so :) ) You need to set the correct bandwidth for serial links using the bandwidth command. Make sure you understand that the bandwidth command is just an informational command that tells the different routing protocols about the actual bandwidth of an interface. This command has nothing to do with the data transmission rate.

In other words: If you have a strict hub and spoke topology then you can leave split horizon turned on and the sites will know about each other through the hub. But if you have a fully meshed FR network with a hub and spoke topology then you must turn off split horizon so that each spoke can talk to other spokes without going through the hub.

David, We are currently running a small F.R. network over here and something you wrote contradicted what we currently have in operation.. Currently we have a hub and spoke topology, 3 spokes to be exact... we are an IP, partial meshed network running subinterfaces and EIGRP.. You mentioned in your paper that you need to turn off ip split-horizon on the subinterfaces if the spokes are to know about the other spokes networks.. Well in our case we don't have ip split horizons turned off and the spokes know about all other spokes... How could this be? I had my lead engineer look @ this and we both cant figure out this discrepancy between what you published and what we are currently running over here...

Re: Sniffer in switch
Go to the fastethernet interface configuration mode for the interface on which you have the sniffer. In this configuration mode use the command : port monitor [interface | vlan vlan-id] here are a few usage guidelines :) ( from cisco ) Enabling port monitoring without specifying a port causes all other ports in the same VLAN to be monitored. Entering the port monitor vlan 1 command causes monitoring of all traffic to and from the IP address configured on VLAN 1. ATM ports are the only ports that cannot be monitor ports. However, you can monitor ATM ports. The following restrictions apply for ports that have port-monitoring capability: A monitor port cannot be in a Fast EtherChannel or Gigabit EtherChannel port group. A monitor port cannot be enabled for port security. A monitor port cannot be a multi-VLAN port. A monitor port must be a member of the same VLAN as the port monitored. VLAN membership changes are disallowed on monitor ports and ports being monitored. A monitor port cannot be a dynamic-access port or a trunk port. However, a static-access port can monitor a VLAN on a trunk, a multi-VLAN, or a dynamic-access port. The VLAN monitored is the one associated with the static-access port. Port monitoring does not work if both the monitor and monitored ports are protected ports. - Original Message - From: Choy, Wai Yew [EMAIL PROTECTED] To: 'Atif Awan' [EMAIL PROTECTED]; Choy, Wai Yew [EMAIL PROTECTED]; 'Cisco Groupstudy' [EMAIL PROTECTED] Sent: Thursday, June 01, 2000 3:01 PM Subject: RE: Sniffer in switch Hi Atif, Thanx for the prompt responseErr...What's the command to do that on the 2924 switch.:( Choy Wai Yew -Original Message- From: Atif Awan [mailto:[EMAIL PROTECTED]] Sent: Thursday, June 01, 2000 5:58 PM To: Choy, Wai Yew; 'Cisco Groupstudy' Subject: Re: Sniffer in switch Configure the SPAN ( Switched Port Analyzer ) feature on the switch.

Re: design question (long post)
I am not very good at designing but here goes my try .. 1. Well, OC-x does not necessarily run ATM. There is a technology called POS ( Packet over SONET) and i have heard that MCI will be shifting over to POS soon. And who said oyu would have to run LANE ? 2. I will go for OSPF too and since it is a hub and spoke topology why dont you look into ODR ( On Demand Routing ). Whats bothering me is that how will you terminate all the WAN connections to a single Cat 6000. You do not need your own AS unless you plan to have a redundant ISP connection from another carrier. In that case you will need to do some extensive BGP policy making. If, however, you have no such plans then a static default route will do -- tell me guys if i am missing something here.. 3. the firewall needs to be in between the router that connects to the outside world ( the internet ) and your internal network. 4. Not sure about that to be honest but i dont think a cat 6000 can terminate all the T1s u r looking at but if it can then its the best choice. Regards Atif -Original Message- From: Jeff DeLoach [EMAIL PROTECTED] To: '[EMAIL PROTECTED]' [EMAIL PROTECTED] Date: Tuesday, May 30, 2000 8:55 PM Subject: design question (long post) Hello all, I've recently been given the task of building my company's WAN from the ground up, and have been going over design after design, and finally think I've found a solution. I would be interested in some input from people on this list, though, who have more experience w/ this sort of thing than I do--I've been doing WAN stuff for nearly 2 years now, but nothing on this scale...Here's the scenario: We have nearly 200 sites that need to connect back to the central office, a number that is constantly growing. These sites are scattered all over the US--10 different states right now, with more to come as the year rolls on. I need to provide all the sites with internet access, as well as allow the staff here in the main office to communicate, both via email (and, eventually, w/ video via Netmeeting or ICQ), and with Reachout to remotely troubleshoot sites. Each site has a database that is between 10-50 Mb that needs to be backed up at the home office once a week ; additionally, each site also runs our proprietary software that we seem to constantly upgrade, so we need to be able to send updates across the wire as well. Down the road, the development team is looking at moving to an ASP-based model, which would remove the need for each site to have an individual database or software upgrade, but would really increase the amount of traffic on the WAN links. Additionally, the designers are also looking at employing streaming video to the desktop for the remote sites as well, so the bandwidth requirements are rather large, and multicast needs to be taken into consideration as well. Here's the scenario I proposed: We would get an OC-3 pipe from MCI-WorldCom here at our main site, which would then in turn connect to a Cisco 6000-series switch w/ a router module in it. The main OC pipe would then be broken into T1 links and sent out to each site via MCI's frame cloud. Each site will have a Cisco 2610 router that will connect to a lower-end switch, probably a Catalyst 1900, to allow all users at each site (usually between 30-60 people) to connect to the internet and be in touch w/ the home office. I want to set up queuing on the router to allow video traffic to have the highest priority. In effect, I'm setting up the main office as sort of an ISP--this is the way it has to be, for political and financial reasons. All the satellite sites must connect back to us, and then go out to the internet. All sites run only TCP/IP. Now, here are my questions. 1. From what MCI tells me, OC-x links are ATM. I want to use frame relay to connect the remote sites, rather than have the 2610's at each site have to perform LANE--I don't even know if they do LANE or not. The 6000-series switch is a pretty powerful piece of equipment, but am I asking too much of it to handle all the work here? I've scoured Cisco's website, and I can't find out if the 6000 will do LANE either. How would I go about translating ATM cells to Frame Relay frames? 2. What sort of routing protocol should I use? I was thinking of OSPF, simply because I don't want to clog up the links w/ routing table advertisements. The remote sites won't be talking to each other all that much--I'm envisioning more of a "hub-and-spoke" kind of arrangement. Also, will I need to use BGP at the main site, and make one big AS out of my home site and all my remote sites? 3. Where would you put a firewall in this design? 4. Is the 6000 switch/router idea the best way to go here, or should I have a pure router, like a 7000-series? OK, that's all. Thanks for reading this far. All comments welcome, feel free to pick this design apart if you wish. Like I said, I've been doing this for nearly 2 years, but nothing on this sort of scale, and
