Configuring RIPng
For example, to advertise the summarized prefix 2001:db8::/36 instead of the IPv6 address
2001:db8:0:adff:8935:e838:78:e0ff with a prefix length of 64 bits from Ethernet interface 3/1,
enter the following commands.
Brocade(config)# interface ethernet 3/1
Brocade(config-if-e100-3/1)# ipv6 address 2001:db8:0:adff:8935:e838:78:
e0ff /64
Brocade(config-if-e100-3/1)# ipv6 rip summary-address 2001:db8::/36
Syntax: [no] ipv6 rip summary-address ipv6-prefix/prefix-length
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 Brocade device interface increases the metric of an incoming RIPng route it learns by an offset
(the default is one). The device then places the route in the route table. When the 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.
Brocade(config)# interface ethernet 3/1
Brocade(config-if-e100-3/1)# ipv6 rip metric-offset 1
Brocade(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 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 device can use
RIPng to advertise the route to its RIPng neighbors.
