Configuring RIP parameters
Configuring RIP parameters
Use the following procedures to configure RIP parameters on a system-wide and individual
interface basis.
Enabling RIP
RIP is disabled by default. To enable RIP, you must enable it globally and also on individual
interfaces on which you want to advertise RIP. Globally enabling the protocol does not enable it on
individual interfaces. You can enable the protocol on physical interfaces as well as virtual routing
interfaces. When you enable RIP on a port, you also must specify the version (version 1 only,
version 2 only, or version 1 compatible with version 2).
To enable RIP globally, enter the following command.
Brocade(config)# router rip
Syntax: [no] router rip
After globally enabling the protocol, you must enable it on individual interfaces. To enable RIP on an
interface, enter commands such as the following.
Brocade(config)# interface ethernet 1/1
Brocade(config-if-e1000-1/1)# ip rip v1-only
Syntax: [no] ip rip v1-only | v1-compatible-v2 | v2-only
Configuring metric parameters
By default, a Brocade device port increases the cost of a RIP route that is learned or advertised on
the port by one. You can configure individual ports to add more than one to a learned or advertised
route’s cost.
Loop prevention The method a Brocade device uses to prevent routing
loops caused by advertising a route on the same
interface as the one on which the Brocade device
learned the route.
•
Split horizon – The Brocade device does not
advertise a route on the same interface as the
one on which the Brocade device learned the
route.
•
Poison reverse – The Brocade device assigns a
cost of 16 (“infinite” or “unreachable”) to a route
before advertising it on the same interface as
the one on which the Brocade device learned the
route.
Split Horizon
NOTE: Disabling
poison reverse
enables split
horizon on the
interface.

Advertising and
learning specific
routes You can control the routes that a Brocade device
learns or advertises. The Brocade device
learns and advertises
all RIP routes on all
interfaces. page 323
