Hello guys:- Senario:- I have a Cisco 4000 router. Ser 0 is direct connect to ISP through 64 K leased line. Now I installed another 128 K leased line which connect to my HQ. From there connect to another ISP. How can I ? 1. configure the router to do load balancing or in case ser 0 is down then it will route to my HQ. 2. which routing protocol I should use? (OSPF/IGRP...) 3. example of the routing table... Thanks in advance.
