Path Control: Configuration

Steps

1. Create an ACL to capture interesting traffic
   
   
   
   (config)# ip access-list extended CLIENT1
   
   (config-ext-nacl)# permit ip host 192.168.1.20 any log
   
   (config)# ip access-list extended CLIENT2
   
   (config-ext-nacl)# permit tcp host 192.168.1.21 any eq telnet
   
   (config-ext-nacl)# permit tcp host 192.168.1.21 any eq 443
   
   
   
2. Create a route-map utilising the ACL
   
   
   
   (config-route-map)# match ip address <acl>
   
   (config-route-map)# set ip next-hop <ip>
   
   
   
3. Enable policy-based routing on an interface
   
   
   (config-if)# ip policy route-map <name>
   
     
   OR
    
   
   Apply the route map to traffic sourced from the router itself
   
     
   (config)# ip local policy route-map <name>
