For example, to redistribute OSPFv3 routes into RIPng, enter the following command.
device(config)# ipv6 router rip
device(config-ripng-router)# redistribute ospf
Syntax:
[no] redistribute
{
bgp
|
connected
|
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 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
1/3/1, enter the following commands.
device(config)# ipv6 prefix-list routesfor2001 permit 2001:db8::/32
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 1/3/1, 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.
