Preference - HP FlexNetwork 3600 v2 Series Command Reference Manual

View
OSPF view
Default level
2: System level
Parameters
ip-address: Neighbor IP address.
cost value: Specifies the cost to reach the neighbor, in the range of 1 to 65535.
dr-priority dr-priority: Specifies the neighbor DR priority, in the range of 0 to 255. The default
neighbor DR priority is 1.
Description
Use peer to specify a neighbor, and the DR priority of the neighbor.
Use undo peer to remove the configuration.
On an X.25 or Frame Relay network, you can configure mappings to make the network fully meshed
(any two routers have a direct link in between), so OSPF can handle DR/BDR election as it does on
a broadcast network. However, since routers on the network cannot find neighbors via broadcasting
hello packets, you need to specify neighbors and neighbor DR priorities on the routers.
After startup, a router sends a hello packet to neighbors with DR priorities higher than 0. When the
DR and BDR are elected, the DR will send hello packets to all neighbors for adjacency
establishment.
The cost set with the peer command is the cost to the specified neighbor on the P2MP link. If no cost
is specified, the cost to the neighbor equals the local interface's cost.
A router uses the priority set with the peer command to determine whether to send a hello packet to
the neighbor rather than for DR election. The DR priority set with the ospf dr-priority command is
used for DR election.
Related commands: ospf dr-priority.
