IPv6 Addressing Configuration

Configuring a Static IPv6 Address on a VLAN

Syntax:. [no] ipv6 address < network-prefix >< device-identifier >/< prefix-length > anycast

If IPv6 is not already enabled on a VLAN, this command option does the following:

■enables IPv6 on the VLAN

■configures a link-local address using the EUI-64 format

■statically configures an anycast address

If IPv6 is already enabled on the VLAN, then the above commands statically configure an anycast address, but has no effect on the current link-local address.

anycast: Identifies the specified address as an anycast address. This allows the address to be duplicated (as an anycast address) on other devices on the same network.

Default: None.

The no form of the command erases the specified anycast address and, if no other IPv6- enabling command is config­ ured on the VLAN, disables IPv6 on the VLAN. (Refer to “Disabling IPv6 on a VLAN” on page 4-16.)

To verify the identity of anycast addresses configured for VLANs to which the switch belongs, use the show run command.

To view all currently configured IPv6 unicast addresses, use the following:

■show ipv6 (Lists IPv6 addresses for all VLANs configured on the switch.)

■show ipv6 vlan < vid > (Lists IPv6 addresses configured on VLAN < vid >.)

For more information, refer to “View the Current IPv6 Addressing Configura­ tion” on page 4-21.
