Only if it matches one of the conditions:
access-list 11 permit 155.100.7.0 0.0.0.255
access-list 12 permit 155.100.77.0 0.0.0.255
route-map test permit 10
match ip address 11 12 <--Commands entered separately
set as-path prepend 2 2 2 2
route-map test permit 20
This produced the following output:
Network Next Hop Metric LocPrf Weight Path
* 155.100.7.0/24 155.100.7.7 0 0 2 2 2 2 2 i
* 155.100.77.0/24 155.100.7.7 0 0 2 2 2 2 2 i
* 155.100.177.0/24 155.100.7.7 0 0 2 i
