Configuring Ipv4 And Ipv6 Protocol Stacks - Cisco IE-4000 Software Configuration Manual

Configuring IPv6 Unicast Routing
Configuring IPv6
DETAILED STEPS
Command
1. configure terminal
2. interface interface-id
3. ipv6 nd router-preference {high |
medium | low}
4. end
5. show ipv6 interface
6. copy running-config startup-config
Use the no ipv6 nd router-preference interface configuration command to disable an IPv6 DRP.
EXAMPLE
This example shows how to configure a DRP of high for the router on an interface:
Switch# configure terminal
Switch(config)# interface gigabitethernet0/1
Switch(config-if)# ipv6 nd router-preference high
Switch(config-if)# end

Configuring IPv4 and IPv6 Protocol Stacks

Follow this procedure to configure a Layer 3 interface to support both IPv4 and IPv6 and to enable IPv6 routing.
BEFORE YOU BEGIN
Before configuring IPv6 routing, you must select an SDM template that supports IPv4 and IPv6. If not already configured,
use the sdm prefer dual-ipv4-and-ipv6 {default | routing | vlan} global configuration command to configure a template
that supports IPv6. When you select a new template, you must reload the switch by using the reload privileged EXEC
command so that the template takes effect.
Purpose
Enter global configuration mode.
Enter interface configuration mode, and enter the Layer 3
interface on which you want to specify the DRP.
Specify a DRP for the router on the switch interface.
Return to privileged EXEC mode.
Verify the configuration.
(Optional) Save your entries in the configuration file.
