For IGRP & EIGRP

For OSPF

After understanding your need, BGP should be the best choice for your network.

Re: Load balance

Hi Manjunath,

Routing protocols are capable of load-balancing.

AFAIK, you have two equal paths, so u can do it with OSPF. just configure the OSPF protocol and give following commands.

Router(config)#router ospf

Router(config-router)#maximum-paths ?

<1-6> Number of paths

Router(config-router)#maximum-paths

where x is the number of available paths.

To verify the config, give

Router#show ip cef

OR

Router#show ip route

remember, this will work only for equal cost. For unequal cost, you can do load-balancing by IGRP or EIGRP protocols.

Hope this helps you, if i have misunderstood you then you can explain your need in detail.
