from CCO: Lab Exam Content and Equipment Changes CCIE candidates should note changes to the technical content and equipment in the lab exam. Effective October 1st, 2002, candidates will no longer be tested in the areas of IGRP, Token Ring, Token Ring Switching, or IPX. Note: DLSW+ will remain as a protocol that can be tested in the lab.

Re: Discussion of BGP related to a DR solution [7:26147]
Thanks for the reply- I'm following you. We need traffic to be down no longer than an hour.

Discussion of BGP related to a DR solution [7:26147]
Interested in feedback on using BGP as a Disaster Recovery and/or Load Balancing solution: BACKGROUND Currently, we have one production datacenter (COLO) (DC1) with 2 100MB feeds to redundant 7200s, 2 ip class C blocks (say 1.1.1.x and 2.2.2.x) one behind each 7200. this is a Cisco failover setup with all Cisco gear - mirrored 6509s., local directors, PIXs, etc). primary and secondary DNS are behind 7200 and a firewall on a DMZ. Third dns server is at separate corp site (CORP) on DMZ which is connected via backend T1 on another VLAN... way behind the 7200s. Anyway, to the fun part: OBJECTIVE: Goal is to bring up a disaster recovery data-center (DC2) (another location/provider) where by we could route traffic to this new site should production site go down (within an hour). It doesn't have to be utilized normally for complete loadbalancing, as it won't have all the hardware, redundancy, etc. that DC1 has. This site would have its own class C block (say 3.3.3.x) allocated from this new hosting center/ISP with backend T1 to corp and perhaps a backend T1 to product DC1 for incremental DB replication/administration, etc. Still trying to finish my CCNP, I'm a relative newbie with BGP, however based on my understanding we were thinking that BGP would help solve this problem by creating one AS comprised of the IP blocks at both locations (1&2 from DC1 and 3 from DC2). We could inject weighted static routes into each ISPs AS respectively and if the primary site failed traffic on the internet destined for both 1.1.1.x and 2.2.2.x would be routed over to DC2. I realize that there are many more details regarding the BGP setup but I'm trying to narrow down the functional - high level architecture to communicate internally for project approval. Is that a correct understanding? That is, can BGP function this way? I'm wondering if anyone else out there is doing this and can speak to whether (or not) BGP can help us out.

Re: 3660 router [7:11917]
Don't know what's going on with yours, but we had the same problem with a 3660 and it was the memory. Are you getting any sort of error message when it boots? Our's said that the Image checksum didn't match the expected value. TAC seemed to know the problem right away and sent us out new memory overnight. That fixed the problem right up. The only thing I can think of is that they may have sent you another bad set of mem when the swapped it for you. Sorry I couldn't be of more help. I'll see if the person here who called TAC got any more ideas out of Cisco and get back to you if there are any other known issues that cause this problem.
