Hi,

Access-list are just ways to allows or deny hosts based on few parameter like Destination,Source IP address, port, protocols etc.

Whereas , Route-Maps are the way to Policy Based Routing in Cisco IOS.

Route-Maps are like software programming,

1.you can use to manipulate the whether routes can be installed in the routing table or not ,

2.to what extent the metric of route needs to changed,

3.In BGP to change/set the attributes of routes.

Many of the times Route-Maps make use of access-lists

e.g

access-list 10 permit 192.168.1.0 0.0.0.255

route-map test-route-map

match ip address 10

In above example route-map test-route-map used the access-list 10 to match the IP Addresses.

HTH...rate if helpful...
