We have two BGP handoffs within the Data Center that is load-balancing and working fine. We have a MAN with 10 gig ethernet between the Campus and a remote office. We just installed a new BGP router and handoff at the Campus and running into obvious routing issues. We are experiencing routing loops and asymetrical routes. Here is an excerpt from our DC MPLS router:
router eigrp x
redistribute static
redistribute bgp 1234 route-map bgp_all
network 10.48.x.10 0.0.0.0
network 10.48.x.x 0.0.0.3

Here is the configuration for the Campus router:
router eigrp x
network 10.48.x.x 0.0.0.0
network 10.50.x.x 0.0.0.7
network 10.50.x.x 0.0.0.3
no auto-summary
!
router bgp 12345
no synchronization
bgp log-neighbor-changes
network x.x.x.x mask 255.255.255.252
neighbor x.x.x.x remote-as 43210
neighbor x.x.x.x soft-reconfiguration inbound
no auto-summary
If we are at the campus, we to locally go out the WAN for MPLS sites. If at the DC, we would locally go out the local MPLS routers. The remote sites would need to come back to the same router as they went out on. The complicating factor is the EIGRP between the two routers and the speed/delay preference.
