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 using the
ing IPv6 over IPv4" on page 15-7
The following configurable interface parameters are set to their default values, unless otherwise speci-
•
fied when the ip interface command is used:
IPv6 interface parameters
mtu
ra-send
ra-max-interval
ra-managed-config-flag
ra-other-config-flag
Refer to the ipv6 interface
regarding these parameters.
Each VLAN can have one IPv6 interface. Configuring both an IPv4 and IPv6 interface on the same
•
VLAN is allowed. Note that VLAN interfaces of both types are not active until at least one port associ-
ated 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,
•
however, can only exist on one interface. For example, if an interface for a VLAN 100 is configured
with address 4100:1000::1/64, an interface for VLAN 200 cannot have address 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
To create an IPv6 interface for a 6to4 tunnel, the following command is used:
-> ipv6 interface v6if-6to4 tunnel 6to4
