Chapter 36 Configuring IPv6 Unicast Routing
Configuring IPv6
To remove a configured static route, use the no ipv6 route ipv6-prefix/prefix length {ipv6-address |
interface-id [ipv6-address]} [administrative distance] global configuration command.
This example shows how to configure a floating static route to an interface. The route has an
administrative distance of 130:
Switch(config)# ipv6 route 2001:0DB8::/32 gigabitethernet0/1 130
For more information about configuring static IPv6 routing, see the “Implementing Static Routes for
IPv6” chapter in the Cisco IOS IPv6 Configuration Library on Cisco.com.
Configuring RIP for IPv6
Before configuring the switch to run IPv6 RIP, you must:
• Enable routing by using the ip routing global configuration command.
• Enable the forwarding of IPv6 packets by using the ipv6 unicast-routing global configuration
command.
• Enable IPv6 on any Layer 3 interfaces on which IPv6 RIP is to be enabled.
Beginning in privileged EXEC mode, follow these required and optional steps to configure IPv6 RIP:
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
ipv6 router rip name Configure an IPv6 RIP routing process, and enter router
configuration mode for the process.
Step 3
maximum-paths number-paths (Optional) Define the maximum number of equal-cost routes
that IPv6 RIP can support. The range is from 1 to 64, and the
default is 4 routes.
Step 4
exit Return to global configuration mode.
Step 5
interface interface-id Enter interface configuration mode, and specify the Layer 3
interface to configure.
Step 6
ipv6 rip name enable Enable the specified IPv6 RIP routing process on the interface.
Step 7
ipv6 rip name default-information {only |
originate}
(Optional) Originate the IPv6 default route (::/0) into the RIP
routing process updates sent from the specified interface.
Note To avoid routing loops after the IPv6 default route (::/0)
is originated from any interface, the routing process
ignores all default routes received on any interface.
• only—Select to originate the default route, but suppress all
other routes in the updates sent on this interface.
• originate—Select to originate the default route in addition
to all other routes in the updates sent on this interface.
Step 8
end Return to privileged EXEC mode.
