enable cef

ip cef

then go to the outside interfaces and do one of the following

ip loadshaer per-pack OR per-flow

per-pecket will give 50% 50% loadbalncing but it is CPU intensive

now make tow defua;lt routes withthe same AD each one point to to of your internet connection

ip route 0.0.0.0 0.0.0.0 [int1]

ip route 0.0.0.0 0.0.0.0 [int]

i assumed you already configured NAT on the router interfaces

good luck

Master Controller and Border Router Configuration on a Single Router

The following example, starting in global configuration mode, shows an OER master controller and border router process deployed on a single router:

Router(config)# key chain OER

Router(config-keychain)# key 1

Router(config-keychain-key)# key-string KEYSTRING2

Router(config-keychain-key)# exit

Router(config-keychain)# exit

Router(config)# oer border

Router(config)# logging

Router(config-oer-br)# master 10.100.1.1 key-chain OER

Router(config-oer-br)# local Loopback 0

Router(config-oer-br)# exit

Router(config)# oer master

Router(config-oer-mc)# logging

Router(config-oer-mc)# border 10.100.1.1 key-chain OER

Router(config-oer-mc-br)# interface Ethernet 0/0 external

Router(config-oer-mc-br-if)# exit

Router(config-oer-mc-br)# interface Ethernet 1/1 external

Router(config-oer-mc-br-if)# exit

Router(config-oer-mc-br)# interface Ethernet 2/2 internal

Router(config-oer-mc-br-if)# exit

Router(config-oer-mc-br)# exit

Router(config-oer-mc)# exit

Router(config)# ip route 0.0.0.0 0.0.0.0 Ethernet 0/0

Router(config)# ip route 0.0.0.0 0.0.0.0 Ethernet 1/1

Router(config)# end

pls check the above example, i think it is using as performance routing.

ur cef command is working.

could u help me whether above mentioned configuration is also using in load balancing?
