Ip ospf network
WebNBMA (non-broadcast multiple access) is one of four network types in the OSPF (Open Shortest Path First) communications protocol. NBMA is used to accurately model X.25 and frame relay environments in multiple-access networks where there are no intrinsic broadcast and multicast capabilities. The other OSPF network types are: broadcast , ...

The syntax is as follows: Router (config-if)# ip ospf process-id area area-id For R1, remove the network commandsby using the no form of the network commands.
WebBy default OSPF will try to discover neighbors on the same segment. Since frame-relay is NBMA this is impossible so we have to tell OSPF that it can’t use multicast (if you can’t use broadcast, multicast also doesn’t work). If you use “ip ospf network broadcast” then OSPF will use multicast packets and tries to discover neighbors on its own.
