Redistributing routes into RIPng
You must specify the ipv6-prefix parameter in hexadecimal using 16-bit values between colons as
documented in RFC 2373.
You must specify the prefix-length parameter as a decimal value. A slash mark (/) must follow the
ipv6-prefix parameter and precede the prefix-length parameter.
To stop the advertising of the summarized IPv6 prefix, use the no form of this command.
Changing the metric of routes learned and
advertised on an interface
A router interface increases the metric of an incoming RIPng route it learns by an offset (the default
is 1). The Brocade device then places the route in the route table. When the Brocade device sends
an update, it advertises the route with the metric plus the default offset of zero in an outgoing
update message.
You can change the metric offset an individual interface adds to a route learned by the interface or
advertised by the interface. For example, to change the metric offset for incoming routes learned by
Ethernet interface 1/1/4 to 1 and the metric offset for outgoing routes advertised by the interface
to 3, enter the following commands.
Brocade(config)#interface ethernet 1/1/4
Brocade(config-if-e10000-1/1/4)#ipv6 rip metric-offset 1
Brocade(config-if-e10000-1/1/4)#ipv6 rip metric-offset out 3
In this example, if Ethernet interface 1/1/4 learns about an incoming route, it will increase the
incoming metric by 2 (the default offset of 1 and the additional offset of 1 as specified in this
example). If Ethernet interface 1/1/4 advertises an outgoing route, it will increase the metric by 3
as specified in this example.
Syntax: [no] ipv6 rip metric-offset offset-value
The valid value for offset-value are from 1 to 16.
Syntax: [no] ipv6 rip metric-offset out outgoing-offset-value
The valid value for outgoing-offset-value are from 1 to 15.
To return the metric offset to its default value, use the no form of this command.
Redistributing routes into RIPng
You can configure the Brocade device to redistribute routes from the following sources into RIPng:
• IPv6 static routes
• Directly connected IPv6 networks
• OSPF V3
When you redistribute a route from IPv6 or OSPF V3 into RIPng, the Brocade device can use RIPng
to advertise the route to its RIPng neighbors.
When configuring the Brocade device to redistribute routes, you can optionally specify a metric for
the redistributed routes. If you do not explicitly configure a metric, the default metric value of 1 is
used.
For example, to redistribute OSPF V3 routes into RIPng, enter the following commands.
