Re: Extended Ping and data pattern
I would like to know whether somebody really found a problem in the CSU/DSU or the cables by varying the pattern in the extened ping? What is the relation between the patterns and problems? Say if I got CRCs when using 0x, what does this mean? CSU/DSU or cable?

DLSW MAC for ethernet address
Hi all, I think this has been talked about for a while at least the related questions. I just want to make sure that I understand it correct: if I use " dlsw remote-peer 0 tcp x.x.x.x dest-mac" here, the mac address will be one in the remote ethernet lan, so I should use non-cannonical format, right?

Re: Juniper
So why is Juniper better than cisco 12000? I think because it is faster, but anybody knows why? I think the basic technology Juniper is using should not have too many difference compared with Cisco, MPLS, ASIC, etc.., so why they can be faster and better? does it because their software is better or something else? if anybody knows some comparision reports that will be great.

Re: Juniper
I could not figured out why Juniper does not allow us to get access to the documentation of their OS, we can only read the old version, but no way to get the documnetation of the new version, do they want to people to learn it and use it or what? Unless there is some other reasons, this is so stupid. While Cisco just started, the internet was just started for commerical use, it was that crusial back then so cisco was lucky to be one of the poineers, nowdays I do not think many will risk their stability and waste the experience of engineers just for a little faster speed, perhaps not little, but still I do not think it outweighs the risk. Espcially, Juniper does not look like very inerested in technical support, at least to me.

The largest OSPF area 0
Group, We are trying to design an OSPF network for one of our clients who has about 300 routers. About 60 of them are in the Centeral Office, the rest of them are all remotes. We are thinking of put the 60 routers in the centeral into Area 0 and also put some of the remote ABRs into Area 0 too. The question for your experts out there is: in the largest OSPF network you have seen, how many routers are in Area 0? What is the maximun number of the routers in a non-backbone area? I know there are some deisign guides out there, but I just want to get an idea what you guys seeing in the real world. Any inputs will be helpful.

Re: The largest OSPF area 0
Brian, I am pretty sure there is no easy answer for my question. That is why I am more interested in you guys experience, if somebody says an OSPF area should not be larger than 50 routers(I read this from some books) and one of us jumps up and say I have designed one with 1000 routers in one area ans it is working fine. Then I would like to ask that guy what kind of routers he used at hub sites and remotes, and etc.. Of course, if you have a general rule between the RAM/CPU and the number of the routers in the area, please let us know. I believe many of us want to learn that. Because reading books and caculating on the paper is some thing different than implementing something, at least it happens to me all the time. When say we are designing a network, it normally means our clients are ready to take whatever suggestions we give to them to improve their network. It makes sense that we will use total-stub area and nssa-area whereever possible and it we believe a router in an area of 2000 routers needs to have 128M, we just suggest them to buy it or just reduce the number of routers in the area. Please understand that I am not asking a detailed design for me, again, I am really interested in exchanging some of you guys experience on the scaling of OSPF. As Priscilla said 50 is the number Cisoc suggested, I read this from some books too, but there are many areas larger than this, but I want to know how far can I go? Not only one area also the whole OSPF network, Bill mentioned that 1million routers in one OSPF network, has anybody seen one network OSPF AS of 100 million routers?

Re: Token Ring and the CCIE Lab
Don, Do not think you need to have token-ring, I do not have them and do not have Cat too, I just rent some rack time when I needed to get familiar with basic configuration, I heard DLSW stuffs are there. But you do not need token-ring to practice DLSW. As far as you can configure the it, it should be fine. Even if you have a token-ring interface, what can you do with it execpet the basic 'ring-speed, soure-route 1 1 10, soure-route spanning", that is pretty much it is. I know many people just read book, get 3 or 4 router setup frame-relay and rent rack time if needed, and get CCIE. I personelly, really do not believe buying 6-7 routers and Cat for home lab, not necessary at all, again, my opnion.

Strange Encryption Problem
All, We have a PRI line running CET encryption between two 7206s both have 11.2 version. The strange thing we found out is that we put the 'crypto map xxx" under the pri interface, we started a extended ping, everything was okay, after 3 or 4 mins, the it started loosing pakets, then the ping could not make at all.(but sometimes, we could get one pakets out of 100 pings) Without encryption, everyting is okay. When this happens, the CPU utilization of both the routers are just about 2%. The production crypto access-list is a huge one, I created a testing one just has one access-list, and put it under the pri, everyting was okay with this one, but as soon as we put the production encryption on, the strange thing happens. I was told that this configuration was working for a while and then all a sudden it just has this problem. We opened a case with TAC, have not got any response yet. Any suggestion will be appreciated. Jack _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Re: Possible phony CCIE
Please give us a break. There are 4 CCIE certifications, why? I would assume a R/S CCIE does not know anyting about 8600 is acceptable, right? So you ask him a bug about Checkpoint, why not Windows 98, Linux or tons of those bugs in IE or Outlook? Even if it is something relates to R/S, but the guy may spend 12 project on an VoIP project, and did not know anything about a new PIX, so what? You do not expect people work 10 hours in the office and read the news, releases and bugs on CCO everynight, do you? You should ask John Chambers and see if he knows a bug in checkpoint, it is really amasing.

Re: NAT again --- tough
Jim, My experience with NAT between DCs is you can not use PAT, you have to map the address of the DCs statically. If this is internet connection related, why not nat at the internet router? if this is private address overlapping, you have to give the BDC an address sperated from other traffic, means, DCs use NAT and others use PAT.

I see what you want to do. I guess you could create a tunnel with soure and destination as the public address, put your private address on the tunnel, eable routing throught the tunnel or just use static route. it should work.

How to verify the CIR from my router?
All, Just want to ask how I could verfify/display the CIR of my PVC? I know we could throw traffic to verify this, but I just got a new PVC on a production router(we just add a new PVC on our production T1), so I can not push traffic to the production router just to verify the PVC. Is there any other ways to verify the CIR?

Re: IS-IS use??
Guys, Sorry for jumping into this. I think I agree with Bob that IS-IS is more like something a service provider should consider. OSPF is sufficient for enterprise network, at least I think so, just imagine a network with 3000 or more routers, how could we design a OSPF network like this? how many routers do we want to put into area 0, I never had a chance to work with a network at this level, but would like to know how it works. IS-IS definitely has the ability to handle a network at this scale, it is more robust than OSPF. I think the reason that not too many people like IS-IS is that enterprise or small service providers really do not need IS-IS, OSPF is sufficient. If you do not work with it, you do not know it well, and you do not like a thing that you do not know well.

Re: IS-IS use??
I am not familiar with the ISP enviroment at all. When we say UUNet uses IS-IS on their core, do we mean that they redistribute their BGP routes from their edge routers into IS-IS and redistribute back into BGP and the far end edge routers? Which means the edge routers are running BGP to learn customers' routes and redistribute these routes into IS-IS to router across the UUNet core? Just want to verify that I understand this correctly.
