1.
Create a layer 2 interface.
host1(config)# interface atm 5/3
host1(config-if)# interface atm 5/3.101
2.
(Optional) Create a primary IPv6 interface.
host1(config-if)# ipv6 address 1::1/64
host1(config-if)# exit
3.
Create the shared IPv6 interface.
host1(config)# interface ipv6 si0
4.
Associate the shared IPv6 interface with the layer 2 interface by the following
method:
host1(config-if)# ipv6 share-interface atm 5/3.101
5.
To fully configure the shared interface, assign an address (or make the interface
unnumbered).
host1(config-if)# ipv6 address 1::1/64
interface ipv6
■
Use to create an IPv6 interface for interface sharing.
■
Use the specified name to refer to the shared IPv6 interface; you cannot use the
layer 2 interface to refer to them, because the shared interface can be moved.
■
Example
host1(config)# interface ipv6 si1
■
Use the no version to delete the IPv6 interface.
■
See interface ipv6
ipv6 share-interface
■
Use to specify the layer 2 interface used by a shared IPv6 interface. The command
fails if the layer 2 interface does not yet exist. The command is not supported
(that is, it fails) if you use an RSVP tunnel (for example,
tunnel mpls:1 ) to identify
the layer 2 interface.
■
After creating the shared IPv6 interface, you can configure it as you do any other
IPv6 interface.
■
The shared interface is operationally up when the layer 2 interface is operationally
up.
■
You can create operational shared IPv6 interfaces in the absence of a primary
IPv6 interface.
■
Example
host1(config-if)# ipv6 share-interface atm 5/3.101
