Subnet Mask Subnet mask that is used for the source address. This mask
identifies the host address bits used for routing to specific subnets.
Upstream
Neighbor
The IP address of the network device immediately upstream for this
multicast delivery tree.
Interface The IP interface on this switch that connects to the upstream
neighbor. (See chapter 3 “Displaying Subnet Information”.)
Metric The metric for this interface used to calculate distance vectors.
Up Time The time elapsed since this entry was created.
Displaying the DVMRP Neighbor Table
The DVMRP Neighbor Table contains the switch’s DVMRP neighbors, as discovered by
receiving DVMRP protocol messages.
Parameter Description
Interface The IP interface on this switch t hat connects to the upstream neighbor.
(See chapter 3 “Displaying Subnet Information”.)
Neighbor
Address
The IP address of the network device immediately upstream for this
multicast delivery tree.
UpTime The t ime since this device last became a DVMRP neighbor to this
switch.
ExpireTime The time remaining before t his entry will be aged out.
Version The neighboring router’s DVMRP version number.
Rcv Route The total number of routes received in valid DVMRP packets from this
neighbor. This can be used to diagnose problems such as unicast
route injection, as well as giving an indication of the level of DVMRP
route exchange activity.
3.7.6.5.OSPF Table You can use this menu to display the OSPF router linkages for the autonomous system
based on the Link State Table, Neighbor Table, and Virtual Neighbor Table.
Parameter Description
Interface Table
Link State Table Displays a summary link state advertisements.
Neighbor Table Displays current neighbor routers.
Virtual Neighbor Table Displays current virtual neighbors.
Displaying the Interface Table
The OSPF Interface Table contains the parameters of OSPF interfaces configured on
this router.
