Brocade FastIron Ethernet Switch Layer 3 Routing Configuration Guide - Manual (Page 220)

RIP routers, including the Brocade device, also can modify a route cost, generally by adding to it, to
bias the selection of a route for a given destination. In this case, the actual number of router hops may
be the same, but the route has an administratively higher cost and is thus less likely to be used than
other, lower-cost routes.
A RIP route can have a maximum cost of 15. Any destination with a higher cost is considered
unreachable. Although limiting to larger networks, the low maximum hop count prevents endless loops
in the network.
Brocade devices support the following RIP versions:
• Version 1 (v1)
• V1 compatible with v2
• Version 2 (v2, the default)
RIP parameters and defaults
You can configure global RIP parameters for the protocol and interface RIP parameters on those
interfaces that send and receive RIP information.
RIP global parameters
RIP global parameters TABLE 49
Parameter Description Default
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.
Disabled
Administrative distance The administrative distance is a
numeric value assigned to each
type of route on the device.
When the device is selecting from
among multiple routes (sometimes
of different origins) to the same
destination, the device 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.
