Equipment needs - WAS: Why not supernetting?
It is, of course, unethical for me to name names, but I do know of at least one high school with 600 or so workstations, where the Cisco sales force sold a 6509! I am also currently working with a client ( large and profitable publicly held company ) that is deploying 6509s in a number of warehouses as the main machine for the computers used in that part of their operation. 150 or so in each warehouse, they tell me, and quote "not that much traffic" Actually, each warehouse will have a 6509 and a 2924, linked via fiber. The customer was adamant that they wanted the 100 megabit link because gigabit was too expensive. (!) I asked one of the engineers why they were going with such high end equipment. I said I could get them excellent performance with 3548's at a lot lower cost, since they seemed concerned with expenses. The guy kinda winked and told me the engineers pushed through the 6509 because they wanted to be able to play with the advanced features. Well, hey, I can relate to that. ;- Chuck -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Peter A van Oene Sent: Saturday, November 11, 2000 7:52 PM To: [EMAIL PROTECTED] Subject:Re: Why not supernetting?

RE: FXS and FXO?
In the VoIP world, just about all of the terminology comes from the telco/PBX world. The FXO interface connects to a PBX ( or PSTN ) and dial tone is obtained from there The FXS interface provides dial tone such that you can plug a phone directly into it and call another phone connected via an FXS port on another router. If you have a copy of Cisco Config Maker, you can put together scenarios and get an idea of how it works. I did a quick look through the new Cisco Press book Integrating Voice and Data Networks, but could not find an index entry for either FXO, FXS, or EM, the other PBX interface you need to know if you are planning on doing VoIP in conjunction with PBX's. A quick search of CCO came up with a number of links. http://www.cisco.com/univercd/cc/td/doc/product/access/acs_mod/cis2600/softw are/voice.htm watch the wrap looks good for informational/eductional purposes http://www.cisco.com/cpress/cc/td/doc/cisintwk/ita/itaf.htm a vocabulary sheet.

RE: OSPF Totally Stubby Areas and area default-cost
Can someone perhaps help educate me here. I have now seen this on a couple of posts, did a bit of reading, and have learned that stub and totally stubby areas are not necessarily limited to a single ingress/egress point. I.e. can have more than one ABR. Area0---Area1 area 1 is a stub area ( or totally stubby, depending upon the LSA, summarization, and default route handling ) Area0--Area1_ABR1 |--Area1_ABR2 still a stub area / totally stubby area What makes and area NOT a stub area? Is it only the summarization / LSA / default route handling? Yes I understand the NSSA, with its ABSR connecting to an outside AS and that information being passed into an OSPF domain in a particular manner. I guess the question is this: other than the NSSA, is EVERY OSPF area either stub or totally stubby? Area0-Area1---| |ABR? |-Area2| would the above layout make and area NOT stubby or totally stubby?

In a stub area, only LSA types 1 (router) 2 (network) and 3 summary) flow within the area. Hence, no routing information concerning prefixes outside of the OSPF domain is injected into the area. In a totally stubby area, the flow of normal type 3 LSA's is halted as well. This leaves the area with no information about any prefixes outside of the area. In order to allow traffic to exit the area, a single type 3 LSA is propagated by each ABR which advertises a default route. The default cost nob simply allows you to set a cost for the route instead of using the standard OSPF metric to the ABR itself.

From what I'm reading, one of the qualifications of a totally stubby area is that if multiple exits (ABRs) exist, routing to outside the area does not have to take an optimal path. Does this mean that each router within the area picks the closest ABR as the gateway to everything outside the area, and that there is no way to control the default route? If so, does that imply that the area default-cost is used for incoming routes? Would incoming routes even exits if the area was a totally stubby area?

Re: Question about eigrp
Hmmm- a couple things you have described don't seem EIGRP-like. The network @ the office is EIGRP stubs are usually set as passive or not set EIGRP @ all. In both cases they're alive can transmit thought the network, but only"a little help from their friend" (their directly connected neighbor). Now- the stub command may be needed when multiple connection run to a dead end or solo router (I have never had this issue). Witha default gateway, this surprises me... EIGRP would not be doing it's job of discoveringof a successor or feasible, with static commands. Changing path cost I have seen, but default- anything I don't recommend. If your network is small, this may not be issues. My job deals with over 1300 EIGRP routers we have to follow EIGRP to the letter or itthings go crazy (whichhappens anyway from time to time :-) If you ever get a chance, pick up EIGRP Network Design Solutions (Cisco Press). As for the 12.7T, what model of router ??? We have been sooo leery with the 12.0's, especially in the 7500 series (when it comes to EIGRP). I could check a few devices, but I can tell you DES, LANE, EIGRP do not exist well beyond 11.2 (22a)... Let me know, I actually get to talk from some experience here :-) Good Luck !!!

RE: OSPF Totally Stubby Areas and area default-cost
It actually has little to do with physical topology (noted exception of NSSA). They real differentiator is which LSA's flow within the area, and ultimately, what level of knowledge does the area have about the outside world. The stub concept involves the trade off of sub optimal routing for less LSA flooding. In a large OSPF domain, a huge number of Type 5 LSA's can be created which will flood area wide. Sometimes, this can overwhelm the processing of a smaller area and hence the stub concept makes sense. The trade off is, without the first hand knowledge via LSA type 4's about where each ASBR lives, these routers in stub areas may not always take the fastest path toward a external prefix.

In a stub area, only LSA types 1 (router) 2 (network) and 3 summary) flow within the area. Hence, no routing information concerning prefixes outside of the OSPF domain is injected into the area. In a totally stubby area, the flow of normal type 3 LSA's is halted as well. This leaves the area with no information about any prefixes outside of the area. In order to allow traffic to exit the area, a single type 3 LSA is propagated by each ABR which advertises a default route. The default cost nob simply allows you to set a cost for the route instead of using the standard OSPF metric to the ABR itself.

From what I'm reading, one of the qualifications of a totally stubby area is that if multiple exits (ABRs) exist, routing to outside the area does not have to take an optimal path. Does this mean that each router within the area picks the closest ABR as the gateway to everything outside the area, and that there is no way to control the default route? If so, does that imply that the area default-cost is used for incoming routes? Would incoming routes even exits if the area was a totally stubby area? I would very much appreciate it if someone would please set me straight. Thank you.

Re: Lot of talk about 3548; but is it a VLAN router like the 5000?
As a minimum you need a Supervisor III with a NFFC. The NFFC is a WS-F5521 as opposed to the more expensive NFFC2 WS-F5531/5531A daughtercard. You can use an external router to do the job that the RSM does different environments but you can learn enough to pass using a 2620 as the external RP. There are some differences with ethernet cards as well - WS-X5224 24 port 10/100 blade does not do inline rewrite, WS-X5225 does ... inline rewrite basically transfers the packet rewrite functions of the NFFC/NFFC2 to the level of ASICs in the card. Its not on the test but its a big issue if you're trying to use a 55xx box with its limited backplane. All the 65xx linecards support inline rewrite. I used to work for a reseller that is very active in the education market ... here is some design/pricing wisdom for you. As a base I'd buy a WS-C5505 chassis, a WS-X5530-E2 supervisor, and a WS-X5213A blade. Don't buy a WS-X5213 - won't work in a 55xx chassis even though they physically fit. The chasis is $1950 new in distribution, the 5213A is not more than $1k, and the engine should be not more than $5k. It costs $2100 to upgrade a WS-X5530-E1 to the latest/greatest and those cards can be had for $1500 if you dig ... but keep in mind I am digging, too, and I don't have an approval process to go through when I buy :-) For the RP I'd go with a 2620 if you want something you can put a voice card into later or if you've got an NP-1FE in one of those 4500s you're already set.

I have used The Catalyst 3548 uses the Cisco IOS command set, much like the Catalyst 2924XL. You might want to look into the Catalyst 2948G (not 2948G-L3) for the Catalyst OS command set. It works just like the Catalyst 5000 series without an RSM. Keep in mind that the 2948G does not support ISL trunking though; it only support 802.1Q trunking for your VLAN's).

Re: Lot of talk about 3548; but is it a VLAN router like the 5000?
I think the cheapest way to do the Cat5k stuff is: 2901(basically a 5002, supervisor 1, 5213A (12 port 10/100) blade) 2926T (basically a 5002, supervisor 2, 5224 (24 port 10/100) blade) cost on the 2901 is $1200 - $2000 cost on the 2926T is $1700 - $2500 I have also been quoted 5002's, supervisor 1, 5213 blade (essentially a 2901) for about $2200.

RE: OSPF Totally Stubby Areas and area default-cost
Correction to my own post. I meant to say that the LSA type 5's flood domain wide, not just area wide. *** REPLY SEPARATOR *** On 12/11/2000 at 12:12 PM Peter A van Oene wrote: It actually has little to do with physical topology (noted exception of NSSA). They real differentiator is which LSA's flow within the area, and ultimately, what level of knowledge does the area have about the outside world. The stub concept involves the trade off of sub optimal routing for less LSA flooding. In a large OSPF domain, a huge number of Type 5 LSA's can be created which will flood area wide. Sometimes, this can overwhelm the processing of a smaller area and hence the stub concept makes sense. The trade off is, without the first hand knowledge via LSA type 4's about where each ASBR lives, these routers in stub areas may not always take the fastest path toward a external prefix.

In a stub area, only LSA types 1 (router) 2 (network) and 3 summary) flow within the area. Hence, no routing information concerning prefixes outside of the OSPF domain is injected into the area. In a totally stubby area, the flow of normal type 3 LSA's is halted as well. This leaves the area with no information about any prefixes outside of the area. In order to allow traffic to exit the area, a single type 3 LSA is propagated by each ABR which advertises a default route.

From what I'm reading, one of the qualifications of a totally stubby area is that if multiple exits (ABRs) exist, routing to outside the area does not have to take an optimal path. Does this mean that each router within the area picks the closest ABR as the gateway to everything outside the area, and that there is no way to control the default route? If so, does that imply that the area default-cost is used for incoming routes? Would incoming routes even exits if the area was a totally stubby area?

CiscoPress + what??? (BCRAN)
Hey group, As some of you recall my last post, I just passed my BSCN. I am now moving onto the BCRAN. For the Switching and Routing 2.0 tests I have used CiscoPress + Exam Cram books to get the passing grade. I really like the exam cram's for touch ups on these tests but I have read in many places that the remote access exam cram does not make the grade. I'm wondering if anybody has used this book and whether or not it is a good tool to add to the CiscoPress BCRAN. If not, should I use the CiscoPress BCRAN alone, or are there other good b0oks/materials to go along with it. Any advice would be appreciated.

RE: routing protocols vs Tcp/ip model
Your instructor is one of the all-too-large group of people who try to coerce things into a simplistic OSI model. Priscilla calls this coercing protocols into OSI layers. It's really not the fault of OSI, because there are documents that supplement the original model, such as the Rout(e)ing Framework, Internal Organization of the Network Layer, Management Annex, etc. The OSI stack principally was drawn to show how standard communications service user applications, which run on top of the service interface to the application layer. Management was something of an afterthought, and what is called system management -- think SNMP, or the OSI rough equivalent, CMIP -- does indeed involve an application layer protocol and a management application above it. Routing, error notification, etc., are considered layer management. There is nothing "above" them; they are part of the infrastructure for a given layer. So,all of them are logically layer 3. To further cloud the discussion, I've heard folks argue that MPLS is a layer 2 1/2 protocol, and I've also heard folks argue that MPLS is a layer 3 1/2 protocol since it rides on top of IP (though how something could ride "on top" of IP yet control the data link layer baffles me). Would it be fair to say that MPLS is therefore a Layer 2/3 control protocol, and is therefore outside the typical OSI layers? Or, is it a Layer 3 protocol? _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Again, I must begin by referring to the full OSI specifications, not the reference model alone. The Internal Organization of the Network Layer divides it into three levels: Subnetwork Independent: IP, CLNP, IPX Subnetwork Convergence: ARP Subnetwork Dependent Access: X.25, LLC, etc. Subnetwork dependent access includes what often get called "layer 2.5" protocols. To answer your specific question, consider that a MPLS LSP can have IP endpoints. MPLS is not IP internally, so I would consider it a subnetwork dependent access protocol. The LSPs themselves are in the user plane.

Re: Some OSPF Questions
OK, first a big thanks to everyone who contributed to this one as well as those watching from the sidelines. I believe we're very close to having this one figured out and here's how I've come to this conclusion: I recreated Chuck's experiment with 3 routers on an ethernet segment. I also simultaneously ran a sniffer on the segment to determine what's going on for the 40 seconds or so while the DR is unavailable--that does seem like an awfully long time. So I ran "debug ip ospf events" on the BDR and ovserved the output. Things looked normal--regular send/receipt of Hellos--then I removed the cable connecting the DR from the hub and observed the output. Just what you'd expect...in 40 seconds an election took place..BDR became the DR and the only DROther was now the BDR. Well one odd thing ...the box made a note to "remember" the old DR as indicated by this event msg: 03:16:25: OSPF: Remember old DR 192.2.2.1 (id) I found this odd and I really have no explaination for it?? But the key point is that review of the sniffer capture showed that 5 packets after the DR stopped sending hellos the BDR began sending acks to the DROther on LSAs--as best I can tell, at this time it was still the BDR. CONCLUSION: The process of DR/BDR election after a DR is declared dead appears to be completely independent of the BDR "backing-up" the DR in performance of it's duties. It seems even though the BDR has assumed the "duties" of the DR it remains the BDR until the dead timer expires. While I still don't know the timeframe precisely I must admit the 0.5 second answer given earlier seems like a reasonable SWAG. Any comments are appreciated...Frank "Shaw, Winston Mr." wrote: Chuck, Thanks for testing. Now my curiosity is at an all time high. Is it possible for you to do the test with 4 routers ? My theory is that 2 or maybe even 3 routers are not enough. Here is why: 2 routers on a broadcast net will always have a DR and BDR. If the DR goes away, the DR will know it is alone on a broadcast net. It will become a DR in its own right. It will not be taking over any duties of the former DR. The time to realize that it is alone will be 40 secs(default). A 3 router net might have the same issue. The absence of the DR will trigger a promotion of the BDR. The remaining router will become the BDR. This seems to be consistent with the broadcast net rules. Although the code obviously selects BDRs and DRs very early, maybe the duties of DR flooding do not start until there is at least one other DRother on the net. I only have two routers available and my test produced essentially the same results as yours. Something I did notice is that the Network type 2 LSAs never aged. If a 4 router test produces the same results then it will be difficult to say whether LSAs or hello packets determine when the BDR takes over for the dead DR. I hope they never ask this question on any test.

Hello time is 10 seconds. Dead time 40 seconds ( 4xhello ) I determined which of the two routers was the DR, and which was the BDR I then plugged into and monitored from the BDR, using repeated "show ip ospf neighbor" commands I then unplugged the DR from the ethernet I then repeatedly reissued the show ip ospf neighbor commands I watched. The result of the show command was that the neighbor state FULL/DR remained in effect until the dead time was reached. After that, there was no neighbor. I also plugged it the first router back into the ethernet and repeatedly issued the commands. After a few seconds the first router showed up as a FULL/BDR Of some interest - the debug ip ospf hello and debug ip ospf events were silent immediately after unplugging the DR. It was only after the expiration of the dead time that debug ip ospf events indicated the election of a new DR, to whit, the router I was monitoring. Where this 0.5 second / half second thing comes from I cannot say. But using Cisco's defaults in a quick and dirty lab, it is safe to say that this is not what happens.

RE: Youngest CCNP
I am 21 also and will have mine before 22 (2left with 8 months). I also doubt very highly that this is the youngest. I think that I heard Global Knowledge is sponcering some 12 year old in getting his CCIE (no joke). So I would imagine he/she has their CCNP. Could be wrong though...

Re: System Error message
I found this on cisco's site by inputing %SYS-2-GETBUF, which is the start of the error and this is what I got: IP Routing Protocols CSCdk37681 When you use dynamic address translation, the same global inside address might be used by two or more different inside hosts. In this case, NAT will not work for these hosts. Workaround: Clear the translation table.

There were a couple more that were in this statement but I think these 2 are suited for your problem. Hope I helped...
