Assigning a PPP Sub-Interface to Bridge Group 1
3. If you are bridging and do not wish to route IP, IP routing should be disabled. Enter no ip
routing at the global configuration mode prompt to disable IP routing for all interfaces on the
router. For simple bridging applications (IP traffic is routed and all other protocols are
bridged), IP routing is not disabled and the unit must be properly configured for routing ( the
remote ip address must be on a unique subnet). Also the command bridge 1 route ip must
be issued in global configuration mode to allow IP routing and bridging of other protocols.
Disabling IP Routing
