1148 CHAPTER 76: OSPF CONFIGURATION COMMANDS

p2mp: Specifies the network type as P2MP.

p2p: Specifies the network type as P2P.

Description Use the ospf network-typecommand to set the network type for an OSPF interface.

Use the undo ospf network-typecommand to restore the default network type for an OSPF interface.

By default, the network type of an interface depends on its link layer protocol.

■For Ethernet and FDDI, the default network type is broadcast.

■For ATM, FR, HDLC and X.25, the default network type is NBMA.

■For PPP, LAPB and POS, the default network type is P2P.

Note that:

■If a router on a broadcast network does not support multicast, you can configure the interface’s network type as NBMA.

■If an NBMA network is fully meshed, you can configure the network type for interfaces as NBMA. If not, you need to configure the network type as P2MP for two routers having no direct link to exchange routing information through another router.

■When the network type of an interface is NBMA, you need to use the peer command to specify a neighbor.

■If only two routers run OSPF on a network segment, you can configure associated interfaces’ network type as P2P.

Related commands: ospf dr-priority.

n This command is not supported on the NULL interface.

Examples # Configure the current interface’s network type as NBMA.
