Routing Over ATM

Cisco, cam

R7(config)# interface atm 1/0

R7(config-if)# pvc CCIE

R7(config)# interface atm 1/0

R7(config-if)# pvc CCIE

In order for a PVC or SVC to pass routing updates, you must configure the PVC or SVC to pass broadcast traffic. You can do this either per destination on the PVC or SVC by using the broadcast keyword at the end of an ATM mapping statement, or globally for the entire PVC or SVC using the broadcast command.

Routing protocols such as Open Shortest Path First (OSPF) and Enhanced Interior Gateway Routing Protocol (EIGRP) will require you to statically define neighbors in a non-broadcast environment. OSPF will consider ATM a non-broadcast environment by default. You can override this with the use of the ip ospf network command. You can statically define neighbors using the neighbor command within (config-router) mode for the respective routing protocol.
