This chapter provides information and commands concerning a number of IPv6-related topics such as assigning IPv6 addresses to interfaces, IPv6 tunnels, and IPv6 ping.
This chapter is from the book

This chapter provides information and commands concerning the following topics:

  • Assigning IPv6 addresses to interfaces
  • IPv6 and RIPng
  • Configuration example: IPv6 RIP
  • IPv6 tunnels: manual overlay tunnel
  • Static routes in IPv6
  • Floating static routes in IPv6
  • Verifying and troubleshooting IPv6
  • IPv6 ping

Assigning IPv6 Addresses to Interfaces

Router(config)#ipv6 unicast-routing

Enables the forwarding of IPV6 unicast datagrams globally on the router.

Router(config)#interface fastethernet 0/0

Moves to interface configuration mode.

Router(config-if)#ipv6 enable

Automatically configures an IPv6 link-local address on the interface and enables IPv6 processing on the interface.

NOTE: The link-local address that the ipv6 enable command configures can be used only to communicate with nodes on the same link.

Router(config-if)#ipv6 address 3000::1/64

Configures a global IPv6 address on the interface and enables IPv6 processing on the interface.

Router(config-if)#ipv6 address 2001:db8:0:1::/64 eui-64

Configures a global IPv6 address with an interface identifier in the low-order 64 bits of the IPv6 address.

Router(config-if)#ipv6 address fe80::260:3eff:fe47:1530/64 link-local

Configures a specific link-local IPv6 address on the interface instead of the one that is automatically configured when IPv6 is enabled on the interface.

Router(config-if)#ipv6 unnumbered type/number

Specifies an unnumbered interface and enables IPv6 processing on the interface. The global IPv6 address of the interface specified by type/number will be used as the source address.
