seconds (6 minutes), the router removes the entry for that neighbor
from the neighbor table and, if the neighbor is a service node, from
the routing table.

H/W Addr

The node’s LAN address if the neighbor is connected to a LAN. If
the frame relay protocol is running, the H/W Addr is the Data Link
Connection Identifier (DLCI). For X.25 interfaces, the H/W Addr is
the X.25 address of the neighbor.

RIF

Routing Information Field. A sequence of segment and bridge
numbers, in hexadecimal, which indicate a path through the
network between two stations. RIF is required for source routing.

routing-tables

Displays information about each service node known by the router.

Example:

Net Address

The Net Address is a unique, configurable 32-bit hexadecimal value
from 30900000 to 3097FFFF. This range of numbers is assigned to
IBM by Banyan. It is very important that no two routers on a
network are assigned the same Net Address. The Net Address for a
Banyan service node is the 32-bit hexadecimal serial number of the
service node. An S, H, or P preceding the Net Address field
indicates the following:

S:

The service node is in suspended state and is advertised,
for 90 seconds, as being down. After 90 seconds, the router
removes the entry for this service node from the routing
table.

H:

The service node is in hold-down state and is advertised,
for 2 minutes, as being down. After 2 minutes, the router
advertises the service node as operational. If a service
node is in suspended state and it receives an RTP packet,
the service node enters the hold-down state.

P:

After initialization, the X.25 interface enters permanent state
for 4 and 1/2 minutes. After 4 and 1/2 minutes, the neighbor
enters the permanent state and its age stays at 0 while in
this state. If the X.25 interface goes down, the entry is
removed from the routing table.

Next Hop Nbr Addr

The address of the neighbor service node that is the next hop on
the least-cost path to the network.

Nbr Intf

The medium to which the next hop neighbor service node is
attached.

Metric An estimated cost, in 200-milliseconds, to route the VINES packet

to the destination service node.
