Configuring RIPng
When configuring the device to redistribute routes, such as BGP4+ routes, you can optionally
specify a metric for the redistributed routes. If you do not explicitly configure a metric, the default
metric value of one is used.
For example, to redistribute OSPFv3 routes into RIPng, enter the following command.
Brocade(config)# ipv6 router rip
Brocade(config-ripng-router)# redistribute ospf
Syntax: [no] 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
Brocade device 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::/32 in RIPng routing
updates sent from Ethernet interface 3/1, enter the following commands.
Brocade(config)# ipv6 prefix-list routesfor2001 permit 2001:db8::/32
Brocade(config)# ipv6 router rip
Brocade(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.
Brocade(config)# ipv6 prefix-list 2001routes deny 2001:db8::/64 le 128
Brocade(config)# ipv6 prefix-list 2001routes permit ::/0 ge 0 le 128
Brocade(config)# ipv6 router rip
Brocade(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.
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 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.
If poison reverse is enabled on the RIPng Brocade device, it takes precedence over split horizon (if
it is also enabled).
