Configuring RIPng
45
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 one). 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 3/1 to one and the metric offset for outgoing routes advertised by the interface
to three, enter the following commands.
BigIron RX(config)# interface ethernet 3/1
BigIron RX(config-if-e100-3/1)# ipv6 rip metric-offset 1
BigIron RX(config-if-e100-3/1)# ipv6 rip metric-offset out 3
In this example, if Ethernet interface 3/1 learns about an incoming route, it will increase the
incoming metric by two (the default offset of 1 and the additional offset of 1 as specified in this
example). If Ethernet interface 3/1 advertises an outgoing route, it will increase the metric by 3 as
specified in this example.
Syntax: [no] ipv6 rip metric-offset [out] <1 – 16>
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
• BGP4+
• IPv6 IS-IS
• OSPFv3
When you redistribute a route from BGP4+, IPv6 IS-IS, or OSPFv3 into RIPng, the Brocade device
can use RIPng to advertise the route to its RIPng neighbors.
When configuring the Brocade 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.
BigIron RX(config)# ipv6 router rip
BigIron RX(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.
