Table 67. DVMRP Neighbor table fields
Field Description
Index Identifies the value of the virtual interface index used to reach
the neighbor.
Address Identifies the IP address of the neighbor.
Up Time Indicates how long ago the DVMRP neighbor last became a
neighbor to the SSR.
Expiry Time Indicates the minimum amount of time remaining before the
neighbor's entry will be deleted from the DVMRP Neighbor
table.
Generation ID Identifies the neighboring router's generation identifier.
Major Version Indicates the neighboring router's major DVMRP version
number. The SSR's major version number is 3.
Minor Version Indicates the neighboring router's minor DVMRP version
number. The SSR's minor version number is 255.
Capabilities Describes the neighboring router's capabilities. These
capabilities are:
• Leaf – signifies that the router has only one interface with
neighbors.
• Prune – signifies that the router supports pruning.
• GenerationID – signifies that the neighbor recognizes
generation identifiers and sends that information in Probe
messages.
• mtrace – signifies that the neighbor can handle mtrace
requests. The mtrace command tracks the multicast path
from a source to a receiver.
Rx Routes Indicates how many routes the SSR received in valid DVMRP
packets received from the neighbor.
This figure is useful in diagnosing problems as well as
indicating the level of DVMRP traffic.
Rx Bad Packets Indicates how many invalid packets the SSR received from the
neighbor.
Rx Bad Routes Indicates how many of the neighbor's routes the SSR ignored.
The SSR ignores invalid route entries.
