Configuring RIP

Configuring the RIP Interface Route Tag

Use the ip rip route-tag
face. This value is used to set priorities for RIP routing. Enter the command and the route tag value. For
example, to set a route tag value of 1 you would enter:
-> ip rip route-tag 1
The valid route tag value range is 1 to 2147483647. The default is 0.
Use the show ip rip command to display the current route tag value.

RIP Options

The following sections detail procedures for configuring RIP options. RIP must be loaded and enabled on
the switch before you can configure any of the RIP configuration options.

Configuring the RIP Forced Hold-Down Interval

The RIP forced hold-down timer value defines an amount of time, in seconds, during which routing infor-
mation regarding better paths is suppressed. A route enters into a forced hold-down state when an update
packet is received that indicates the route is unreachable and when this timer is set to a non-zero value.
After this timer has expired and if the value is less that 120 seconds, the route enters a hold-down state for
the rest of the period until the remainder of the 120 seconds has also expired. During this time the switch
will accept any advertisements for better paths that are received.
Note that the RIP forced hold-down timer is not the same as the RIP hold-down timer. The forced hold-
down timer defines a separate interval that overlaps the hold-down state. During the forced hold-down
timer interval, the switch will not accept better routes from other gateways. For more information on RIP
hold-down timer, see
Use the ip rip force-holddowntimer
remains in a forced hold-down state. Enter the command and the forced hold-down interval value, in
seconds. For example, to set a forced hold-down interval value of 10 seconds you would enter:
-> ip rip force-holddowntimer 10
The valid forced hold-down timer range is 0 to 120. The default is 0.
Use the show ip rip

Configuring the RIP Update Interval

The RIP update interval defines the time interval, in seconds, when routing updates are sent out. This
interval value must be less than or equal to one-third the value of the invalid timer.
Use the ip rip update-interval
update state. Enter the command and the update interval value, in seconds. For example, to set an update -
interval value of 45 seconds, you would enter:
-> ip rip update-interval 45
The valid update interval range is 1 to 120. The default is 30.
