MULTICAST ROUTING

Displaying Neighbor Information

You can display all the neighboring DVMRP routers.

Command Attributes

•Neighbor Address – The IP address of the network device immediately upstream for this multicast delivery tree.

•Interface – The IP interface on this router that connects to the upstream neighbor.

•Up time – The time since this device last became a DVMRP neighbor to this router.

•Expire – The time remaining before this entry will be aged out.

•Capabilities – A hexadecimal value that indicates the neighbor’s capabilities. Each time a probe message is received from a neighbor, the router compares the capabilities bits with the previous version for that neighbor to check for changes in neighbor capabilities. (Refer to DVMRP IETF Draft v3-10 section 3.2.1 for a detailed description of these bits). These bits are described below:

-Leaf (bit 0) - Neighbor has only one interface with neighbors.

-Prune (bit 1) - Neighbor supports pruning.

-Generation ID (bit 2) - Neighbor sends its Generation ID in probe messages.

-Mtrace (bit 3) - Neighbor can handle multicast trace requests.

-SNMP (bit 4) - Neighbor is SNMP capable.

-Netmask - (bit 5) - Neighbor will accept network masks appended to the prune, graft, and graft acknowledgement messages.

-Reserved (bit 6 and 7) - Reserved for future use.
