Displaying Rip Filters - Dell PowerConnect B-FCXs Configuration Manual

NOTE
By default, routes that do not match a route filter are learned or advertised. To prevent a route from
being learned or advertised, you must configure a filter to deny the route.
To configure RIP filters, enter commands such as the following.
PowerConnect(config-rip-router)#filter 1 permit 192.53.4.1 255.255.255.0
PowerConnect(config-rip-router)#filter 2 permit 192.53.5.1 255.255.255.0
PowerConnect(config-rip-router)#filter 3 permit 192.53.6.1 255.255.255.0
PowerConnect(config-rip-router)#filter 4 deny 192.53.7.1 255.255.255.0
These commands explicitly permit RIP routes to three networks, and deny the route to one network.
Because the default action is permit, all other routes (routes not explicitly permitted or denied by
the filters) can be learned or advertised.
Syntax: filter <filter-num> permit | deny <source-ip-address> | any <source-mask> | any [log]
Applying a RIP route filter to an interface
Once you define RIP route filters, you must assign them to individual interfaces. The filters do not
take effect until you apply them to interfaces. When you apply a RIP route filter, you also specify
whether the filter applies to learned routes or advertised routes:
•
•
To apply RIP route filters to an interface, enter commands such as the following.
PowerConnect(config)#interface ethernet 0/1/2
PowerConnect(config-if-0/1/2)#ip rip filter-group in 2 3 4
These commands apply RIP route filters 2, 3, and 4 to all routes learned from the RIP neighbor on
port 1/2.
Syntax: [no] ip rip filter-group in | out <filter-list>

Displaying RIP filters

To display the RIP filters configured on the router, enter the following command at any CLI level.

Out filters apply to routes the Layer 3 Switch advertises to its neighbor on the interface.
In filters apply to routes the Layer 3 Switch learns from its neighbor on the interface.
