ipv6 general-prefix
This command defines an IPv6 general prefix for the network address segment. Use
the
no
form to remove the IPv6 general prefix.
Syntax
ipv6 general-prefix
prefix-name
ipv6-prefix
/
prefix-length
no ipv6 general-prefix
prefix-name
•
prefix-name
- The label assigned to the general prefix.
•
ipv6-prefix
- The high-order bits of the network address segment assigned
to the general prefix. The prefix must be formatted according to RFC 2373
“IPv6 Addressing Architecture,” using 8 colon-separated 16-bit
hexadecimal values. One double colon may be used in the address to
indicate the appropriate number of zeros required to fill the undefined fields.
•
prefix-length
- A decimal value indicating how many of the contiguous bits
(from the left) of the address comprise the prefix (i.e., the network portion
of the address).
Default Setting
No general prefix is defined
Command Mode
Global Configuration
Command Usage
• Prefixes may contain zero-value fields or end in zeros.
• A general prefix holds a short prefix that indicates the high-order bits used in
the network portion of the address. Longer, more specific, prefixes can be
based on the general prefix to specify any number of subnets. When the
general prefix is changed, all of the more specific prefixes based on this prefix
will also change.
Example
This example assigns a general network prefix of 2009:DB9:2229::/48 to the router.
