Routing Issues

We've got a site to site leased line between a 10.44.5.xx network and

10.44.1.xxx network we've now added another 10.4.0.0 network which is run through a seperate router on the the 10.44.1.xx network

so 10.44.5.251 (cisco 1841) leased line

10.44.1.251 (cisco 1841) 10.44.1.250 (cisco 2600 series) leased line 10.4.0.0 network

Configs for both the 10.44.5.251 and 10.44.1.251 router are shown below, EIGRP has been set on both but i believe this can be removed (however we have tried this but found the connection dropped)

Any advice would be appreciated:

I have not looked too closely, but my initial reaction is it looks like you are wasting CPU cycles running EIGRP. Your statement that "you need EIGRP enabled to keep the connection up" is ambiguous. Do you mean the carrier drops the link or that the link stays up but traffic ceases to flow? The only thing EIGRP appears to be doing in this config is exchanging hello packets so there is always traffic on the link when EIGRP is running, and possibly complete silence when it is not.

Good luck and good hunting!
