Displaying Rip Filters - Foundry Networks FESX Manual

Foundry Configuration Guide for the FESX, FSX, and FWSX
• In filters apply to routes the Layer 3 Switch learns from its neighbor on the interface.
To apply RIP route filters to an interface, enter commands such as the following:
FastIron SuperX Router(config)# interface ethernet 1/2
FastIron SuperX Router(config-if-1/2)# ip rip filter-group in 2 3 4
Syntax: [no] ip rip filter-group in | out <filter-list>
These commands apply RIP route filters 2, 3, and 4 to all routes learned from the RIP neighbor on port 1/2.

Displaying RIP Filters

To display the RIP filters configured on the router, enter the following command at any CLI level:
FESX424 Router> show ip rip

Displays...
The filter number. You assign this number when you configure the
filter.
The action the router takes if a RIP route packet matches the IP
address and sub-net mask of the filter. The action can be one of the
following:
• deny – RIP route packets that match the address and network
mask information in the filter are dropped. If applied to an
interface's outbound filter group, the filter prevents the router from
advertising the route on that interface. If applied to an interface's
inbound filter group, the filter prevents the router from adding the
route to its IP route table.
• permit – RIP route packets that match the address and network
mask information are accepted. If applied to an interface's
outbound filter group, the filter allows the router to advertise the
route on that interface. If applied to an interface's inbound filter
group, the filter allows the router to add the route to its IP route
table.
The IP address of the route's destination network or host.
