For example, to advertise the summarized prex 2001:db8::/36 instead of the IPv6 address 2001:db8:0:ad:8935:e838:78:e0 with
a prex length of 64 bits from Ethernet interface 1/3/1, enter the following commands.
device(config)# interface ethernet 1/3/1
device(config-if-e100-1/3/1)# ipv6 address 2001:db8:0:adff:8935:e838:78:
e0ff /64
device(config-if-e100-1/3/1)# ipv6 rip summary-address 2001:db8::/36
Syntax: [no] ipv6 rip summary-address ipv6-prex/prex-length
You must specify the ipv6-prex parameter in hexadecimal using 16-bit values between colons as documented in RFC 2373.
You must specify the prex-length parameter as a decimal value. A slash mark (/) must follow the ipv6-prex parameter and precede the
prex-length parameter.
To stop the advertising of the summarized IPv6 prex, use the no form of this command.
Changing the metric of routes learned and advertised on an interface
A device interface increases the metric of an incoming RIPng route it learns by an
oset (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 oset of zero in an
outgoing update message.
You can change the metric oset an individual interface adds to a route learned by the interface or advertised by the interface. For
example, to change the metric oset for incoming routes learned by Ethernet interface 1/3/1 to one and the metric oset for outgoing
routes advertised by the interface to three, enter the following commands.
device(config)# interface ethernet 1/3/1
device(config-if-e100-1/3/1)# ipv6 rip metric-offset 2
device(config-if-e100-1/3/1)# ipv6 rip metric-offset out 3
In this example, if Ethernet interface 1/3/1 learns about an incoming route, it will increase the incoming metric by two. if the interface
1/3/1 advertises an outgoing route, it will increase the metric oset by 3 as specied in the example. Conguring the default metric (1
for incoming, 0 for outgoing) will be allowed but will not be visible in the show run output for the interface.
Syntax: [no] ipv6 rip metric-oset 1-16
Syntax: [no] ipv6 rip metric-oset out 0-15
To return the metric oset to its default value, use the no form of this command.
Redistributing routes into RIPng
You can
congure the Brocade device to redistribute routes from the following sources into RIPng:
• IPv6 static routes
• Directly connected IPv6 networks
• BGP4+
• OSPFv3
When you redistribute a route from BGP4+ or OSPFv3 into RIPng, the device can use RIPng to advertise the route to its RIPng
neighbors.
When conguring 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 congure a metric, the default metric value of one is used.
