HP MSR2000/3000/4000 Router Series Layer 3 - IP Routing Command Reference

162
Usage guidelines
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, and you can configure the network type for the connected interfaces as NBMA. If two routers
are not directly connected, 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
# Configure the OSPF network type for Ethernet 1/1 as NBMA.
<Sysname> system-view
[Sysname] interface ethernet 1/1
[Sysname-Ethernet1/1] ospf network-type nbma

ospf dr-priority
ospf prefix-suppression
Use ospf prefix-suppression to disable an OSPF interface from advertising all its IP prefixes, except for
the prefixes of secondary IP addresses.
Use undo ospf prefix-suppression to restore the default.
Syntax
ospf prefix-suppression [ disable ]
undo ospf prefix-suppression
Default
Prefix suppression is disabled.
Views

Parameters
disable: Disables prefix suppression on an interface.
Usage guidelines
To disable prefix suppression on an interface associated with an OSPF process that has been enabled
with prefix suppression, execute the ospf prefix-suppression disable command on that interface.
