Foundry Networks FESX User Manual

Foundry Configuration Guide for the FESX, FSX, and FWSX
17 - 2 © Foundry Networks, Inc. December 2005
Foundry Layer 3 Switches support the following RIP versions:
• Version 1
• V1 compatible with V2
• Version 2 (the default)
ICMP Host Unreachable Message for Undeliverable ARPs
If the router receives an ARP request packet that it is unable to deliver to the final destination because of the ARP
timeout and no ARP response is received (router knows of no route to the destination address), the router sends
an ICMP Host Unreachable message to the source.
RIP Parameters and Defaults
The following tables list the RIP parameters, their default values, and where to find configuration information.
RIP Global Parameters
Table 17.2 lists the global RIP parameters and their default values, and indicates where you can find configuration
information.
Table 17.2: RIP Global Parameters
Parameter Description Default See page...
RIP state The global state of the protocol
Note: You also must enable the protocol on individual
interfaces. Globally enabling the protocol does not
allow interfaces to send and receive RIP information.
See Table 17.3 on page 17-3.

Administrative
distance
The administrative distance is a numeric value
assigned to each type of route on the router.
When the router is selecting from among multiple
routes (sometimes of different origins) to the same
destination, the router compares the administrative
distances of the routes and selects the route with the
lowest administrative distance.
This parameter applies to routes originated by RIP.
The administrative distance stays with a route when it
is redistributed into other routing protocols.

Redistribution RIP can redistribute routes from other routing
protocols such as OSPF and BGP4 into RIP. A
redistributed route is one that a router learns through
another protocol, then distributes into RIP.
Disabled 17-6
Redistribution
metric
RIP assigns a RIP metric (cost) to each external route
redistributed from another routing protocol into RIP.
An external route is a route with at least one hop
(packets must travel through at least one other router
to reach the destination).
This parameter applies to routes that are redistributed
from other protocols into RIP.
