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.
