Controlling distribution of routes through RIPng
Brocade(config)# ipv6 router rip
Brocade(config-ripng-router)# redistribute ospf
Syntax: redistribute bgp | connected | isis | ospf | static [metric number]
For the metric, specify a numerical value that is consistent with RIPng.
Controlling distribution of routes through RIPng
You can create a prefix list and then apply it to RIPng routing updates that are received or sent on a
router interface. Performing this task allows you to control the distribution of routes through RIPng.
For example, to permit the inclusion of routes with the prefix 2001:DB8::/16 in RIPng routing
updates sent from Ethernet interface 1/1/4, enter the following commands.
Brocade(config)# ipv6 prefix-list routesfor2001 permit 2001:db8::/16
Brocade(config)# ipv6 router rip
Brocade(config-ripng-router)# distribute-list prefix-list routesfor2001 out
ethernet 1/1/4
To deny prefix lengths greater than 64 bits in routes that have the prefix 2001:DB8::/64 and allow
all other routes received on tunnel interface 1, enter the following commands.
Brocade(config)# ipv6 prefix-list 3ee0routes deny 2001:db8::/64 le 128
Brocade(config)# ipv6 prefix-list 3ee0routes permit ::/0 ge 1 le 128
Brocade(config)# ipv6 router rip
Brocade(config-ripng-router)# distribute-list prefix-list 3ee0routes in
tunnel 1
Syntax: [no] distribute-list prefix-list name in | out interface port
The name parameter indicates the name of the prefix list generated using the ipv6 prefix-list
command.
The in keyword indicates that the prefix list is applied to incoming routing updates on the specified
interface.
The out keyword indicates that the prefix list is applied to outgoing routing updates on the specified
interface.
For the interface parameter, you can specify the ethernet, loopback, ve, or tunnel keywords. If you
specify an Ethernet interface, also specify the port number associated with the interface. If you
specify a VE or tunnel interface, also specify the VE or tunnel number.
To remove the prefix list, use the no form of this command.
Configuring poison reverse parameters
By default, poison reverse is disabled on a RIPng router. If poison reverse is enabled, RIPng
advertises routes it learns from a particular interface over that same interface with a metric of 16,
which means that the route is unreachable.
If poison reverse is enabled on the RIPng router, it takes precedence over split horizon (if it is also
enabled).
To enable poison reverse on the RIPng router, enter the following commands.
