Interface Configuration (VLAN)
Command Usage
• The address specified with this command replaces a link-local address that
was automatically generated for the interface.
• You can configure multiple IPv6 global unicast addresses per interface, but
only one link-local address per interface.
• If a duplicate address is detected, a warning message is sent to the console.
Example
This example assigns a link-local address of FE80::269:3EF9:FE19:6779 to
VLAN 1. Note that the prefix FE80 is required for link-local addresses, and the first
16-bit group in the host address is padded with a zero in the form 0269.
Console(config)#interface vlan 1
Console(config-if)#ipv6 address FE80::269:3EF9:FE19:6779 link-local
Console(config-if)#end
Console#show ipv6 interface
