Filtering IP Routes add ip prefixlist 2-45
Software Version 2.7.5
C613-10454-00 REV A
Examples To match only routes from the 192.168.0.0/16 network, use the command:
add ip prefixlist=sample1 entry=1 action=match
prefix=192.168.0.0 masklength=16
To match all routes in all 192.168.0.0 networks, except those in the 192.168.7.0
network, use the commands:
add ip prefixlist=sample2 entry=1 action=nomatch
prefix=192.168.7.0 masklength=24-32
add ip prefixlist=sample2 entry=2 action=match
prefix=192.168.0.0 masklength=16-32
To exclude the default route, use the command:
add ip prefixlist=sample3 entry=1 action=nomatch masklength=0
To include all routes, use the command:
add ip prefixlist=sample4 entry=1 action=match
masklength=0-32

MASklength The range of prefix mask lengths matched by this entry in the prefix
list. The range is either a single CIDR mask from 0 to 32, or two masks
separated by a hyphen. These options are valid for setting the mask
length:
• as a mask length range (masklength=a-b).
For a route to match against this entry, its prefix mask length must
be between a and b inclusive. a must be less than b.
• as a single mask length (masklength=a).
For a route to match against this entry, its prefix mask length must
be exactly a.
• as an implicit mask length, by not specifying masklength (for
example, prefix=192.168.0.0).
For a route to match against this entry, its prefix mask length must
correspond exactly to the mask for the class of the given address;
in this example, 24.
Default: The natural mask for the prefix, based on whether it is a class
A, B, or C network
PREfix The network address matched by this entry in the prefix list, specified
in dotted decimal notation.
If you do not specify a prefix, the router or switch sets it to 0.0.0.0.
This is correct if you are matching all routes or the default route.
Default: 0.0.0.0
