Diverse BGP on Campus - Issues

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

network 10.48.x.x 0.0.0.3

default-metric 10000000 100 255 1 1500

no auto-summary

!

router bgp 1234

no synchronization

bgp log-neighbor-changes

network 0.0.0.0

network 10.48.0.0 mask 255.255.224.0

network 10.48.x.0 mask 255.255.255.0

network 10.48.x.0 mask 255.255.255.0

network 10.50.0.0 mask 255.255.0.0

aggregate-address 10.48.0.0 255.255.224.0 summary-only

aggregate-address 10.50.0.0 255.255.0.0 summary-only

redistribute eigrp x route-map bgp_all

neighbor x.x.x.x remote-as 4321

neighbor x.x.x.x soft-reconfiguration inbound

no auto-summary

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.

Re: Diverse BGP on Campus - Issues

why do you, in your bgp have a network 0.0.0.0 ? + please paste the route-map used in your bgp and eigrp

Re: Diverse BGP on Campus - Issues

The 'network 0.0.0.0' was recommended by our ISP. The 'default-information originate' command should accomplish the same thing.

As far as the route-map, this is just used for our load balancer along with WCCP.
