Currently, I have a 7609 that is multihomed to two different ISP's doing BGP load sharing. My 7609 is also running EIGRP for internal routing in an EIGRP AS comprised of about 30 EIGRP enabled layer3 switch's. All layer3 switch's use my 7609's EIGRP interface as the default route ip for internet access.
My question is, I am fixing to purchase another 7609, and split my BGP peers, each 7609 peering with one ISP. I need to load balance internally, where by the default-route IP will be asscotiated with each 7609 and my outbound traffic load will be split between the two.
I have looked into GLBP, but don't know how it will work with EIGRP? Also, my path needs to be able to failover incase one of my BGP peers goes down.
Any suggestions would be appreciated!
