I haveing two router at same location 3640 & 2610xm with the configuration given below, in 3640 s1/3 (64kbps) and 2610xm s0/3:0(2048kbps) configured for remote location. at remote location both interface are connected at same router. when I do 'no shut' interface 2610xm s0/3:0, interface in 3640 s1/3 become line protocole down, same time remote router get hangs, when i do no shut inter s0/3:0 shut in router 2610xm ,the inter in 3640 s1/3 got up and remote router got normal while interface used in remote is s1/0 and s0/0.
