Function:
To define an IPv6 general prefix. The no form of this command will delete the configuration.
Parameter:
<prefix-name>
is a character string less than 32 characters, to use as IPv6 general prefix name.
<ipv6-prefix/prefix-length>
is defined as IPv6 general prefix.
Command Mode:
Global Mode.
Default:
IPv6 general prefix is not configured by default.
Usage Guide:
If IPv6 general prefix is configured, the interface will use the configured prefix for IPv6 address generating.
Commonly, the general prefix is used for enterprise IPv6 prefix, and when entering an IPv6 address, users can
simply add the address suffix of to the name of the general prefix. The configured address prefix will be reserved in
the general address prefix pool. At most 8 general prefix can be configured at the same time. When trying to remove
a configured general prefix name, the operation will fail if any interfaces used the configured prefix. Only one general
prefix for a prefix name. The general prefix cannot use the same prefix definition with prefixes learnt from prefix
delegation.
Example:
To set the prefix of 2001:da8:221::/48 to general prefix my-prefix.
Switch(config)# ipv6 general-prefix my-prefix 2001:da8:221::/48
