Question : Unix networking issue

I have two seperate networks that are seperated by a T1 connection. The T1 is working as it should, the two networks are controlled by layer 2 cisco switches, there two solaris servers server1 & server2. Server1 is on one end of the T1 and server2 is on the opposite end of the T1. Neither server can ping each other but all switches on both sides of the T1 can ping both servers. The servers are on different vlans but they can ping the local switches at there respective site. Please let me if any one can help, thanks.

Answer : Unix networking issue

Could you provide us the output for the commands "route -n" and "ifconfig -a" in both servers ?
Do you have any other computers in the VLAN 1 that actually communicates with a computer in VLAN 2 (or vice-versa) ? If not, is your switch routing properly ?
