Matching on a community ACL
To configure a route map that matches on community ACL 1:
switch(config)# rbridge-id 5
switch(config-rbridge-id-5)# ip community-list standard 1 permit 123:2
switch(config-rbridge-id-5)# route-map mycommroutemap1 permit 10
switch(config-route-map-mycommroutemap1/permit/10)# match community 1
Matching on a destination network
NOTE
You can use the results of an IP ACL or an IP prefix list as the match condition.
To configure a route map that matches on a destination network:
switch(config)# rbridge-id 5
switch(config-rbridge-id-5)# route-map mynetroutemap1 permit 10
switch(config-route-map-mynetroutemap1/permit/10)# match ip address prefix-list 1
Matching on a next-hop device
To configure a route map that matches on a next-hop device:
switch(config)# rbridge-id-5
switch(config-rbridge-id-5)# route-map myhoproutemap1 permit 10
switch(config-route-map-myhoproutemap1/permit/10)# match ip next-hop prefix-list 1
Matching on a route source
To configure a route map that matches on a route source:
switch(config)# rbridge-id 5
switch(config)# access-list 10 permit 192.168.6.0 0.0.0.255
switch(config-rbridge-id-5)# route-map mysourceroutemap1 permit 1
switch(config-route-map-mysourceroutemap1/permit/10)# match ip route-source prefix-
list 10
Matching on routes containing a specific set of communities
To configure a route map that matches on a set of communities:
switch(config)# rbridge-id 5
switch(config-rbridge-id-5)# ip community-list standard std_1 permit 12:34 no-export
switch(config-rbridge-id-5)# route-map mycommroutemap2 permit 1
switch(config-routemap-mycommroutemap2/permit/1)# match community std_1 exact-match
NOTE
The first command configures a community ACL that contains community number 12:34 and community
name "no-export." The remaining commands configure a route map that matches the community
attributes field in BGP4 routes against the set of communities in the ACL. A route matches the route
map only if the route contains all the communities in the ACL and no other communities.
To configure an additional community-based route map for comparison with the first:
switch(config)# rbridge-id 5
switch(config-rbridge-id-5)# ip community-list standard std_2 permit 23:45 56:78
switch(config-rbridge-id-5)# route-map mycommroutemap3 permit 1
switch(config-routemap-mycommroutemap3/permit/1)# match community std_1 std_2 exact-
match
