Configuring Ipv4 And Ipv6 Protocol Stacks - Cisco ME 3400 Software Configuration Manual

Configuring IPv6
Use the no ipv6 nd router-preference interface configuration command to disable an IPv6 DRP.
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
For more information about configuring DRP for IPv6, see the "Implementing IPv6 Addresses and Basic
Connectivity" chapter in the Cisco IOS IPv6 Configuration Library on Cisco.com.

Configuring IPv4 and IPv6 Protocol Stacks

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.
Beginning in privileged EXEC mode, follow these steps to configure a Layer 3 interface to support both
IPv4 and IPv6 and to enable IPv6 routing.

Purpose
Enter global configuration mode.
Select an SDM template that supports IPv4 and IPv6.
default—Set the switch to the default template to balance
•
system resources.
• routing—Set the switch to the routing template to support
IPv4 and IPv6 routing, including IPv4 policy-based routing.
vlan—Maximize VLAN configuration on the switch with
•
no routing supported in hardware.
Return to privileged EXEC mode.
Reload the operating system.
Enter global configuration mode.
Enable IPv4 routing on the switch.
Enable forwarding of IPv6 data packets on the switch.
Enter interface configuration mode, and specify the Layer 3
interface to configure.
Remove the interface from Layer 2 configuration mode (if it is a
physical interface).
Specify a primary or secondary IPv4 address for the interface.
