When the two links are terminated to this router,how do route the traffic? which route protocol to use? Like: e0 default to s0/0 and e1 to s0/1
Using Cisco2600 Rtr with 2WAN and 2LAN Port.
Please provide me example config.
Thanks in Advance, BS

To what extent is the routing static, and to what extent do you need routing to be redundant? For example, if one of those two WAN connections fail, then do you need the other to take over automatically?
Your example implies that the links are distinct, that at a logical level (E0 S0/0) forms one link and that (E1 S0/1) forms the other link, and that traffic for the two should not mix together. Is that correct? Or should data from (say) E0 sometimes go to S0/0 and sometimes go to S0/1 depending on the destination? If so then how easy is it to express the rules about which destination should be which? And if the other end of S0/0 snuck in a packet addressed to something on the E1 side instead of the E0 side, then what is the importance that that packet be blocked? How about if S0/0 puts in something addressed to what is at the other end of S0/1 ?
In the simple case where the packets can cross over freely, then all you would need is a single 'ip route' statement to send traffic to the default network over the proper link. The more you need the links to be distinct, the more security you need, and the more you need the routing to be dynamic, the more complicated your configuration will get.
