ipv6 address

Function

The ipv6 address command configures a global unicast address for an interface.

The undo ipv6 address command deletes all the configured address on the interface. If no IPv6 address or prefix length is specified in this command, this command, by default, deletes all the configured except the automatically configured link-local address.

Format

ipv6 address [ dhcpv6-pd-prefix-name ] { ipv6-address prefix-length | ipv6-address/prefix-length }

undo ipv6 address [dhcpv6-pd-prefix-name | ipv6-address prefix-length | ipv6-address/prefix-length ]

Parameters
