3.1.44 ospf network-type

Syntax
ospf network-type { broadcast | nbma | p2mp | p2p }
undo ospf network-type
View

Parameters
broadcast: Specifies the network type as Broadcast.
nbma: Specifies the network type as NBMA.
p2mp: Specifies the network type as P2MP.
p2p: Specifies the network type as P2P.
Description
Use the ospf network-type command to set the network type for an interface.
Use the undo ospf network-type command to restore the default network type for an
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 any two routers on an NBMA network are directly connected via a virtual link,
that is, the network is fully meshed, you can configure the network type as NBMA;
otherwise you need to configure it as P2MP for two routers having no direct link to
exchange routing information via 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.
