• XNS
Enable use of the RIF only on Token Ring interfaces on the router.
To configure the Cisco IOS software to append RIF information, use the following command in
interface configuration mode:
For an example of how to configure the software to bridge routed protocols, see the “SRB and
Routing Certain Protocols Example” section later in this chapter.
Configure a Static RIF Entry
If a Token Ring host does not support the use of IEEE 802.2 TEST or XID datagrams as explorer
packets, you might need to add static information to the RIF cache of the router.
To configure a static RIF entry, use the following command in global configuration mode:
Configure the RIF Timeout Interval
RIF information that can be used to bridge routed protocols is maintained in a cache whose entries
are aged.
Note The rif validate enable commands have no effect on remote entries learned over RSRB.
To configure the number of minutes an inactive RIF entry is kept in the cache, use the following
commands in global configuration mode:
Command Purpose
multiring {protocol-keyword [all-routes | spanning] | all |
other}
Enable collection and use of RIF
information.
Command Purpose
rif mac-address rif-string
{interface-name | ring-group
ring}
Enter static source-route information
into the RIF cache.
Step Command Purpose
1 rif timeout minutes Specify the number of minutes an inactive
RIF entry is kept.
2 rif validate-enable Enable RIF validation for entries learned on
an interface (Token Ring or FDDI).
3 rif validate-enable-age Enable RIF validation on an SRB that is
malfunctioning.
4 rif validate-enable-route-cache Enable synchronization of the RIF cache with
the protocol route cache.
