BGP Multihoming with 2 ISP with 1 router each site
Hi how do you configure BGP in the below scenario?
R1/R2 = Customer Router
R1 connected to ISP1 and ISP2, R2 to ISP1 and ISP2, R1 connected to R2. So far most design and configuration I have seen is R1 to ISP1, R2 to ISP2, R1 to R2.
How much redundancy do you want?
I implemented a similar situation, except I ran a layer two network with a couple of VLAN's between the two routers and VRRP on the ISP interface so that if one router failed the toher would take over and still maintain my BGP adjacency with both ISP's - I also ran an iBGP between the two routers, and had the link to the "inside" vias my firewall running VRRP as well.
If you don't need that kind of redundancy, then your way will work - just run iBGP between the two routers and let them sort out the best route between them.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
