6.21.3.3 Displaying Neighbor Information
The router 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
draft-ietf-idmr-dvmrp-v3-11.txt section 3.2.2 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.
