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. Appreciate anyone's ideas or feedback- Byron _________________________________________________________ Do You Yahoo!?
