Parameters

ip-address: Specifies a neighbor by its IP address.

cost cost-value: Specifies the cost to reach the neighbor, in the range of 1 to 65535.

dr-priority priority: Specifies the DR priority for the neighbor, in the range of 0 to 255. The default neighbor DR priority is 1.

Usage guidelines

In an NBMA or P2MP network, OSPF packets are sent in unicast, so you must use this command to specify neighbors.

The cost set with the peer command applies only to P2MP neighbors. 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.

Examples

# Specify the neighbor 1.1.1.1.

<Sysname> system-view
[Sysname] ospf 100
[Sysname-ospf-100] peer 1.1.1.1
