OK Cisco Guru's..Moderatly difficult config help is needed. Scenario: I have a rather large frame-relay network. 35 sites connecting back to a central Datacenter. Branch sites connect via 2 T1 circuits each (1 ATT, 1 MCI and a single Cisco 2651xm) to T3 ports from each (MCI and ATT) on a single Cisco 7206 at the datacenter. We have now added a DR site with another DS3 and 4k ports at each remote site. Each site has to connect through the central datacenter to connect to each other and to the internet. Currently I am doing equal cost load balancing with EIGRP and I wish to keep EIGRP. I do not want any traffic over the DR network unless all other T1 paths are down. I beleive I can accomplish this by working with the bandwidth and delay statements. Any help would be appreciated.
