I have this routing problem and need some help please.
two 6509 switches as core switches in the datacenter runing 255 vlans. have hsrp between them. due to some L2 issues our L2 designer at the last momenet revert all on VLAN1 on one of the 2 6506 core routers. so, all traffic from the datacenter gets to vlan1 (L3) interface on core router 6506 1.
there are two core routers connected via two vertical links to two border routers (no cross links between the core routers and border routers due to lack of facility on the MUX connecting these core routers to border routers).
Now, trffic on core 1 router, always reaches border 1 router and out to the Internet using our first BGP border routers and to the provider. naturally EIGRP sees two hops and higher cost and wont send traffic to core router 2 which is connected via a vertical connection to my border 2 router and no traffic flows out my second border router using BGP to our second provider?
Traffic comes in though but nothing flows out!?
I was thinking to split my IP block on core 1 router and put static route pointing to core 2 router and while there it knows how to get to border 2 and out our second border oruter out.
is this idea something that might work?
is there any other ways to do this, say by varying the EIGRP parameters and force traffic the other way, some of the traffic at least?
One more qquestion which might sound sily?: do I need to define all the IP blocks (networks) that I hav edefined for BGP on my border routers for EIGRP between the core routers (s of them) and the border routers (2 of them)?
