Configuring an IPv6 Interface

Configuring an IPv6 Interface
The ipv6 interface command is used to create an IPv6 interface for a VLAN or a tunnel. Note the follow-
ing when configuring an IPv6 interface:
•
A unique interface name is required for both a VLAN and tunnel interface.
•
If creating a VLAN interface, the VLAN must already exist. See
more information.
•
If creating a tunnel interface, a tunnel ID or 6to4 is specified. Only one 6to4 tunnel is allowed per
switch, so it is not necessary to specify an ID when creating this type of tunnel.
•
If a tunnel ID is specified, then a configured tunnel interface is created. This type of tunnel requires
additional configuration by using the
Interfaces" on page 17-18
•
Each VLAN can have one IPv6 interface. Configuring both an IPv4 and IPv6 interface on the same
VLAN is allowed. Note that the VLAN interfaces of both types are not active until at least one port
associated with the VLAN goes active.
•
A link-local address is automatically configured for an IPv6 interface, except for 6to4 tunnels, when
the interface is configured. For more information regarding how this address is formed, see
figuration of IPv6 Addresses" on page
•
Assigning more than one IPv6 address to a single IPv6 interface is allowed.
•
Assigning the same link-local address to multiple interfaces is allowed. Each global unicast prefix,
subset of, or superset of a prefix can only exist on one interface. For example, if an interface for VLAN
100 is configured with an address 2001:db8:4100:1000::1/64, an interface for VLAN 200 cannot have
an address 2001:db8:4100:1000::2/64.
•
Each IPv6 interface anycast address must also have a unique prefix. However, multiple devices may
share the same anycast address prefix to identify themselves as members of the anycast group.
To create an IPv6 interface for a VLAN or configured tunnel, enter ipv6 interface followed by an inter-
face name, then vlan (or tunnel) followed by a VLAN ID (or tunnel ID). For example, the following two
commands create an IPv6 interface for VLAN 200 and an interface for tunnel 35:
-> ipv6 interface v6if-v200 vlan 200
-> ipv6 interface v6if-tunnel-35 tunnel 35
