Switching and Routing

ServerIron(config-rip-router)#interface ve 1

ServerIron(config-vif-1)#ip rip v1-only

Syntax: [no] ip rip v1-only | v1-compatible-v2 | v2-only

RIP Timers

ServerIron Release 10.2.00 enhances the current functionality by providing support for RIP timers, such as

update, aging, and garbage collection.

To configure RIP timers, use commands such as the following:

ServerIron(config) router rip

ServerIron (config-rip)# timers-basic 5 15 15

Syntax: [no] timers-basic <update-timer> <aging-timeout-interval> <garbage-collection-timer>

• The <update-timer> specifies how often RIP update messages are sent. You can specify from 1 - 1,000

seconds. The default is 30 seconds.

• The <aging-timeout-interval> specifies how long the Brocade device waits for a route update before declaring

a route invalid. The value specified for the <aging-timeout-interval> should be at least three times the value

specified for the <update-timer>. The <aging-timeout-interval> can be from 3 - 3,000 seconds. The default is

180 seconds.

The <garbage-collection-timer> specifies how long the Brocade device waits for a route update before removing

the route from the RIP route table. The value specified for the <garbage-collection-timer> should be at least three

times the value specified for the <update-timer>. The <garbage-collection-timer> can be from 3 - 3,000 seconds.

The default is 120 seconds.

Redistributing IP Static Routes into RIP

By default, the software does not redistribute the IP static routes in the route table into RIP. To configure

redistribution, perform the following tasks:

• Configure redistribution filters (optional). You can configure filters to permit or deny redistribution for a route

based on the route’s metric. You also can configure a filter to change the metric. You can configure up to 64

redistribution filters. The software uses the filters in ascending numerical order and immediately takes the

action specified by the filter. Thus, if filter 1 denies redistribution of a given route, the software does not

redistribute the route, regardless of whether a filter with a higher ID permits redistribution of that route.

NOTE: The default redistribution action is permit, even after you configure and apply a permit or deny filter.

To deny redistribution of specific routes, you must configure a deny filter.

NOTE: The option to set the metric is not applicable to static routes.

• Enable redistribution.

NOTE: If you plan to configure redistribution filters, do not enable redistribution until you have configured the

filters.

When you enable redistribution, all IP static routes are redistributed by default. If you want to deny certain routes

from being redistributed into RIP, configure deny filters for those routes before you enable redistribution. You can

configure up to 64 RIP redistribution filters. They are applied in ascending numerical order.

NOTE: The default redistribution action is still permit, even after you configure and apply redistribution filters to

the virtual routing interface. If you want to tightly control redistribution, apply a filter to deny all routes as the last

filter (filter ID 64), then apply filters with lower filter IDs to allow specific routes.

To configure a redistribution filter, enter a command such as the following:

1 2 ... 40 41 42 43 44 45 46 47 48 49 50 ... 61 62
