R3303-HP HSR6800 Routers Layer 3 - IP Routing Command Reference

119
unicast: Specifies the P2MP interface to unicast OSPF packets. By default, a P2MP interface multicasts
OSPF packets.
p2p: Specifies the network type as P2P.
Usage guidelines
• For Ethernet, and FDDI, the default network type is broadcast.
• For ATM, FR, and X.25, the default network type is NBMA.
• For PPP, LAPB, HDLC, and POS, the default network type is P2P.
If a router on a broadcast network does not support multicast, configure the network type for the
connected interfaces as NBMA.
If any two routers on an NBMA network are directly connected through a virtual link—the network is fully
meshed, you can configure the network type for the connected interfaces as NBMA. If two routers are not
directly connected, you must configure the P2MP network type so that the two routers can exchange
routing information through another router.
When the network type of an interface is NBMA or P2MP unicast, you must use the peer command to
specify the neighbor.
If only two routers run OSPF on a network, you can configure the network type for the connected
interfaces as P2P.
When the network type of an interface is P2MP unicast, all OSPF packets are unicast by the interface.
Examples
