OSPF Corruption or Duplicate Router ID? [7:52670]
All, Recently I had a situation where I mistakenly loaded a configuration from a TFTP server onto a box but that very config was already on another router. Thus, I ran into a number of problems. One of which was duplicare router ID messages. Although I had changed the loopback and all the other interfaces on this router to what it should have been, it still saw the router ID as a duplicate (a "show ip ospf interface" proved this). I did two things and I am not sure which one corrected the problem... 1) I applied "router-id xxx.xxx.xxx.xxx" (with the correct loop0 address) to apply the correct router-id. 2) I performed a "clear ip ospf process 100" in an effort to bounce the ospf process. Which one actually fixed the problem? Bouncing OSPF or the router ID change?

Re: 2503 PPPoE/DHCP Client (DSL)/NAT [7:52568]
You are correct...the latest 2500 IOS version "c2500-js-l.122-10b.bin" does not support PPPoE. Thanks!

2503 PPPoE/DHCP Client (DSL)/NAT [7:52568]
Has anyone successfuly implemented a 2500 series router acting as a PPPoE DHCP Client in an DSL environment. I'd like to remove my Linksys entirely from my network since it provides too little functionality and control. If anyone has done so I would be interested in seeing how they configured this and under what IOS image. Thanks in advance. Robert D.

RE: EIGRP default route distribution. [7:52377]
oddly enough, they all did fall in the 172.26.128.0/24 network as follows: Eisenhower loop0 is 172.26.128.1 255.255.255.0 Nixon loop0 is 172.26.128.2 255.255.255.0 Kennedy loop0 is 172.26.128.3 255.255.255.0 Roosevelt loop0 is 172.26.128.4 255.255.255.0 Instead, I changed them all to 255.255.255.255 addresses so each host was advertised individually as it's own network and it worked fine. I know this would work in OSPF, but it seems that EIGRP handles it differently.

RE: EIGRP default route distribution. [7:52377]
Ah! "redistribute static", and removing the "default-network" worked! The other option would have forced EIGRP to run on the interface I was running RIP on, and thus would defeat the purpose of what I was trying to do. Only one problem...why cannot I not get to the loopback addresses I have placed on each router and included in the eigrp 1 process as network 172.26.128.0/24? Any ideas? Thanks guys!

EIGRP default route distribution. [7:52377]
I have the following network in my home lab: Internet RouterEisenhowerRooseveltNixonKennedy The Internet Router (192.168.1.1) runs RIP. Eisenhower (E0:192.168.1.100 and S0:172.26.1.9) runs RIP and EIGRP. Roosevelt, Nixon, and Kennedy run EIGRP for the 172.26.1.0,172.26.128.0,192.168.3.0, and 192.168.4.0 networks. I am peforming redistribution of EIGRP into RIP on the internet router which also hosts my LAN of 192.168.1.0). I am unable to propagate the default route out to the rest of the EIGRP routers being Roosevelt, Nixon and Kennedy. Any one have a clue on what I am missing?

Help with On-line LAB [7:52243]
All, I am looking for anyone interested in taking a trial in an on-line administered lab consisting of: (3) 2503's and (1) 2502. You will also be provided with a network map and access to the network TFTP and FTP servers. If you are interested in taking a 2 hour trial session please contact me at [EMAIL PROTECTED] for more information. Again, this is free and of no charge (and is not intended for any promotional purposes) in an effort to assist me in determining the overall integrity of this network. I assume this would be of help to any future CCNA/CCNP who needs to get a feel for the IOS and troubleshooting. Thank you. Robert D.

RE: Network size [7:49704]
Than answer has nothing to do with users, but to do with how much they will utilize the segment. No more than 30% utilization is the standard threshold on an ethernet segment. Utilization on a WAN link should be no higher than 70%.

RE: Proper network design? [7:49536]
I re-read your initial question... I would assume that 192.168.0.100 is also acting as a router...if this is true, then this would work... Is the cellular device also acting as a router?

RE: Proper network design? [7:49536]
I understand this configuration, but question how the 192.168.2.2 machine knows how to get back to the 192.168.0.20. I don't question that it will work, but if it is not a router interface with 2 addresses from each segment defined, then what default gateway does the 192.168.2.2 machine use? If this configuration is as you stated, and the static route is in place, then there must also be a route defined in the machine on the 192.168.2.2 that routes off it's subnet to the 192.168.0.1 interface of the router. In other words, your 192.168.2.2 machine also has a static route (default route) defined on it to know how to get to the other segment (ie, forwarded to the 192.168.0.1 router interface).

I assume you are using primary and secondary IP address on this one ethernet interface (which is creating the "router on a stick" effect)? Rob Frank H wrote: > > Yes, I am using a 2514.

Cisco Press - Building Scalable Cisco Networks [7:49562]
Awesome book. Probably the best I have read of all technical boooks to date. One question for those of you who have used or are using this book On page 126 it shows a configuration for a single area, with 2 routers having 2 different process ID's. I am confused as to why anyone would do this as multiple process ID's add overhead to the CPU. I was always under the impression that multiple OSPF instances should only need to be run in certain obscure situations. In reading this, it looks to me like this is an error. HELP?

OSPF Startup? [7:49493]
Can someone clarify this for me? During OSPF Start up when is the DR/BDR election done? The BSCN books states it is in this order: - Routing Table is Generated Down State Init State 2way State (bidirection communication established) - DR/BDR Election ExStart State (DR/BDR election done) Full State So the routing table is first populated for each router, then the DR and BDR are elected?

I am seeking my CCIE, to keep myself in the market. I have my CCNA, but know that I need to keep my hands on the stuff to learn it. What kind of lab environment do you suggest. Should I buy one that will fit the CCNP or just get one that includes a 5500 for the CCIE? What do you think?
