device(config)# ipv6 router rip
device(config-ripng-router)# distribute-list prefix-list routesfor2001 out
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 3/1, enter the following commands.
device(config)# ipv6 prefix-list 2001routes deny 2001:db8::/64 le 128
device(config)# ipv6 prefix-list 2001routes permit ::/0 ge 0 le 128
device(config)# ipv6 router rip
device(config-ripng-router)# distribute-list prefix-list 2001routes in
Syntax: [no] distribute-list prefix-list name { in | out }
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.
To remove the distribution list, use the no form of this command.
Configuring poison reverse parameters
By default, poison reverse is disabled on a RIPng Brocade device. 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.
Enabling poison reverse on the RIPng Brocade device disables split-horizon and vice versa. By
default, split horizon will be enabled.
To enable poison reverse on the RIPng Brocade device, enter the following commands.
device(config)# ipv6 router rip
device(config-ripng-router)# poison-reverse
Syntax:[no] poison-reverse
To disable poison-reverse, use the no form of this command.
By default, if a RIPng interface goes down, the Brocade device does not send a triggered update for
the interface’s IPv6 networks.
To better handle this situation, you can configure a RIPng Brocade device to send a triggered update
containing the local routes of the disabled interface with an unreachable metric of 16 to the other
RIPng routers in the routing domain. You can enable the sending of a triggered update by entering the
following commands.
device(config)# ipv6 router rip
device(config-ripng-router)# poison-local-routes
Syntax: [no] poison-local-routes
To disable the sending of a triggered update, use the no form of this command.
