Configuring RIPng
BigIron RX(config)# interface ethernet 3/1
BigIron RX(config-if-e100-3/1)# ipv6 rip default-information originate
Syntax: [no] ipv6 rip default-information only | originate
The only keyword originates the default routes and suppresses all other routes from the updates.
The originate keyword originates the default routes and includes all other routes in the updates.
To remove the explicit default routes from RIPng and suppress advertisement of these routes, use
the no form of this command.
Advertising IPv6 address summaries
You can configure RIPng to advertise a summary of IPv6 addresses from a router interface and to
specify an IPv6 prefix that summarizes the routes.
If a route's prefix length matches the value specified in the ipv6 rip summary-address command,
RIPng advertises the prefix specified in the ipv6 rip summary-address command instead of the
original route.
For example, to advertise the summarized prefix 2001:469e::/36 instead of the IPv6 address
2001:469e:0:adff:8935:e838:78:e0ff with a prefix length of 64 bits from Ethernet interface 3/1,
enter the following commands.
BigIron RX(config)# interface ethernet 3/1
BigIron RX(config-if-e100-3/1)# ipv6 address 2001:469e:0:adff:8935:e838:78:
e0ff /64
BigIron RX(config-if-e100-3/1)# ipv6 rip summary-address 2001:469e::/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 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.
