Configure Bridging of Routed Protocols

VINES

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:

Command

Purpose

multiring {protocol-keyword[all-routes spanning] all

Enable collection and use of RIF

other}

information.

 

 

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:

Command

Purpose

rif mac-address rif-string {interface-name ring-group

Enter static source-route information

ring}

into the RIF cache.

 

 

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:

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.
