Neighbor tab

The Neighbor tab displays the DVMRP neighbors, which are the multicast routers that have an interface on the same network.

The table below describes the fields in the Neighbor tab.


Field Description
Interface
The DVMRP slot/port number or the virtual interface (VLAN) used to reach this DVMRP neighbor.
Address
IP address of the DVMRP neighbor for which this entry contains information.
ExpiryTime
Time remaining before this DVMRP neighbor is aged out.
GenerationId
Neighboring router's generation ID number.
MajorVersion
Neighboring router's major DVMRP version number.
MinorVersion
Neighboring router's minor DVMRP version number.
Capabilities
Neighboring router's capabilities. The probe flag is 1 byte long with the lower 4 bits containing the following information:
  • The leaf bit (0) indicates that the neighbor has only one interface with neighbors.
  • The prune bit (1) indicates that the neighbor supports pruning.
  • The generationID bit (2) indicates that the neighbor sends its generation ID in probe messages.
  • The mtrace bit (3) indicates that the neighbor can handle mtrace requests.
State
State of neighbor adjacency:
  • oneway--The switch sees a packet from the neighbor but no adjacency has been established.
  • active--Adjacency exists in both directions.
  • ignoring--The switch ignores neighbor packets.
  • down--The interface is not enabled.
