For a P2MP interface,
z
If the
unicast
keyword is not specified, the interface sends packets to multicast addresses.
z
If the
unicast
keyword is specified, the interface sends packets to unicast addresses. In this case,
you must use the
peer
command to specify the neighbor.
Note that you must use the
peer
command to configure the peer if the network type of the interface is
NBMA or manually changed to NBMA with the
ospf network-type
command.

Examples
# Set the network type of the interface VLAN-interface 10 to NBMA.

View

Parameters
seconds:
Dead interval of the OSPF neighbor. It is in seconds and ranges from 1 to 65535.
Description
Use the
ospf timer dead
command to configure the dead interval of the OSPF neighbor.
Use the
undo ospf timer dead
command to restore the default.
By default, the dead interval is
z
40 seconds for the OSPF peers of
p2p
and
broadcast
interfaces
z
120 seconds for those of
p2mp
and
nbma
interfaces
The dead interval of OSPF peers means that, within this interval, if no Hello message is received from
the peer, the peer will be considered to be invalid. The value of
dead seconds
should be at least four
times of that of the
Hello seconds
. The
dead seconds
for the interfaces on the same network segment
must be identical.
