Solved: Load balance

ntmanjunath · ‎04-23-2008

I need to configure load balance in Cisco router.

The single router WAN interface connected two ISP, one ISP connected serial0 and another ISP is serial1 both the ISPs provided 2MB bandwidth. The LAN side f0/0 and f0/1 connected firewall. I need to do load balance in the router end. Please let me know the sample configuration.

Hi Manju,

pls follow the links below for detail explaination on load balancing.

For IGRP & EIGRP

http://www.cisco.com/warp/public/103/19.html

For OSPF

http://www.cisco.com/warp/public/105/loadbal_cef.html

For BGP

http://www.cisco.com/warp/public/459/40.html

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

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.
