ip community-list
This example shows how to configure a logical AND condition; all community values must match in
order for the list to be processed:
switch# configure terminal
switch(config)# ip community-list standard test1 permit 65534:40 65412:60 no-export
switch(config)#
In the above example, a standard community list is configured that permits routes from the following:
• Network 40 in autonomous system 65534 and from network 60 in autonomous system 65412.
• Peers in the same autonomous system or from subautonomous system peers in the same
confederation.
This example shows how to configure a standard community list that denies routes that carry
communities from network 40 in autonomous system 65534 and from network 60 in autonomous system
65412. This example shows a logical AND condition; all community values must match in order for the
list to be processed.
switch# configure terminal
switch(config)# ip community-list standard test2 deny 65534:40 65412:60
switch(config)#
This example shows how to configure a named standard community list that permits routes from network
20 in autonomous system 40000.
switch# configure terminal
switch(config)# ip community-list standard RED permit 40000:20
switch(config)#
This example shows how to configure an expanded community list that denies routes that carry
communities from any private autonomous system:
switch# configure terminal
switch(config)# ip community-list expanded 500 deny
_64[6-9][0-9][0-9]_|_65[0-9][0-9][0-9]_
switch(config)#
This example shows how to configure a named expanded community list that denies routes from network
1 through 99 in autonomous system 50000:
switch# configure terminal
switch(config)# ip community-list list expanded BLUE deny 50000:[0-9][0-9]_
switch(config)#
