Cisco Cisco IOS Software Release 12.4(2)T

The following configuration example configures an interim border router on a master controller:

Router(config)# key chain OER 

Router(config-keychain)# key 1 

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

Router(config-keychain-key)# exit 

Router(config-keychain)# exit 

Router(config)# oer master 

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

Router(config-oer-mc-br)# interface Ethernet 0/1 internal 

Router(config-oer-mc-br)# end 

This section provides the following example for the OER Application-Aware Routing: PBR feature: 

Telnet traffic is delay sensitive. Long TCP delays can make Telnet sessions difficult to use. The 
following example matches Telnet traffic sourced from the 192.168.1.0/24 network and applies a policy 
to ensure it is sent out through exit links with that have a response time that is equal to or less than 30 
milliseconds: 

Router(config)# ip access-list extended TELNET 

Router(config-ext-nacl)# permit tcp 192.168.1.0 0.0.0.255 any eq telnet 

Router(config-ext-nacl)# exit 

Router(config)# oer-map BLUE 

Router(config-route-map)# match ip address access-list TELNET 

Router(config-route-map)# set delay threshold 30 

Router(config-route-map)# set resolve delay priority 1 variance 20 

Router(config-route-map)# end 

The following example shows TCP application traffic filtered based on port 23 (Telnet):

Router# show oer master appl tcp 23 23 dst policy
