match ip address
match ipv6 address
Use to create a prefix list for route filtering and to specify a list entry a deny
or permit clause for a network address to the prefix list. Use to add entries to
prefix lists.
The prefix list name can be up to 32 characters long.
Specify the position of each entry in the list with the seq (sequence) keyword.
If you do not specify a sequence number, the router uses the value of the last
sequence number plus 5.
Use the ge and le keywords to specify a range of network prefixes. These
keywords have the following values:
prefix length < ge <= 32
prefix length < le <= ge
If you do not specify either the ge or le keyword, an exact match is expected.
Example 1 IPv4; exact match required; the router permits only a route with a
prefix length of 8 and a network address of 151.0.0.0.
host1(config)#ip prefix-list abc permit 151.0.0.0/8
Example 2 IPv6; exact match required; the router permits only a route with a
prefix length of 8 and a network address of 1:0:0:0:0:0:0:5.
host1(config)#ipv6 prefix-list abc permit 1::5/8
Use the no version to remove the specified prefix list or the specified list entry.
See ip prefix-list.
See ipv6 prefix-list.
Use to specify an access list or use with the prefix-list or prefix-tree keyword
to match routes that have a destination network number address that is permitted
by any specified access list, prefix list, or prefix tree.
Example
host1(config-route-map)#match ip address prefix-list abc
Use the no version to delete the match clause from a route map or a specified
value from the match clause.
See match ip address.
Use to match any route that has a destination network number address that is
permitted by the specified access list or prefix list.
Example
host1(config-route-map)#match ipv6 address prefix-list boston
