Displaying Neighbor Information
You can display all the neighboring DVMRP routers.
Command Attributes
• Neighbor Address – The IP address of the network device immediately upstream
• 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.
• 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,
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.
