To apply a prefix list at the global level of RIP, enter commands such as the following.
device(config-rip-router)# prefix-list list1 in
Syntax: no prefix-list name {in | out}
To apply prefix lists to a RIP interface, enter commands such as the following.
device(config-if-e1000-1/1/2)# ip rip prefix-list list2 in
device(config-if-e1000-1/1/2)# ip rip prefix-list list3 out
Syntax: no ip rip prefix-list name {in | out}
In is for Inbound filtering. It applies the prefix list to routes the Brocade device learns from its neighbor
on the interface.
Out is for Outbound filtering. It applies the prefix list to routes the Brocade device advertises to its
neighbor on the interface.
The commands apply RIP list2 route filters to all routes learned from the RIP neighbor on the port and
applies the lists to all routes advertised on the port.
To configure a route-map, enter commands such as the following.
device(config)#access-list 21 deny 160.1.0.0 0.0.255.255
device(config)#access-list 21 permit any
device(config)# route-map routemap1 permit 21
device(config-routemap routemap1)# match ip address 21
device(config)# route-map routemap2 permit 22
The route-map permit routes to two networks, and denies the route to one network.
Syntax: [no] route-map map-name {permit | deny} num
To apply a route map to a RIP interface, enter commands such as the following.
device(config-if-e1000-1/1/2)# ip rip route-map map1 in
Syntax: [no] ip rip route-map name {in | out}
The route-map can be a prefix list or an ACL. Setting this command can change the metric.
In applies the route map to routes the Brocade device learns from its neighbor on the interface.
Out applies the route map to routes the Brocade device advertises to its neighbor on the interface.
The commands apply route map map1 as route filters to routes learned from the RIP neighbor on the
port.
Setting RIP timers
You can set basic update timers for the RIP protocol. The protocol must be enabled in order to set the
timers. The timers command specifies how often RIP update messages are sent.
To set the timers, enter the following commands.
device(config) router rip
device(config-rip-router)# timer 30 180 180 120
Syntax: [no] timers update-timer timeout-timer hold-down-timer garbage-collection-timer
The update-timer parameter sets the amount of time between RIP routing updates. The possible value
ranges from 3 - 21845. The default is 30 seconds.
