Cisco WAAS Part II: Configuration
Share this page:Cisco WAAS Part II: Configuration
There are a few things we need to know before we configure our traffic to utilize the WAAS:
- - The protocol WAAS uses is called WCCP (Web Cache Coordination Protocol)
- - 61 and 62are the Service Identifier Numbers of WCCP protocol (61 for the origin traffic and 62 for the response traffic)
-
Create the Access-List with your WAEs (in this case there are 2):
ip access-list standard Cisco_WAES
permit 10.184.0.196
permit 10.184.0.197
Create 2 Access Lists, one for the traffic originated in your own network towards the destination network (where the other end of WAAS service is), and the second one for the response traffic from the other side of WAAS service.
ip access-list extended OUR_SIDE2OTHER_SIDE
deny tcp host 10.184.116.108 any
permit tcp 10.162.0.0 0.0.255.255 172.15.0.0 0.0.255.255
permit tcp 10.162.0.0 0.0.255.255 172.15.182.0 0.0.255.255
ip access-list extended OTHER_SIDE2OUR_SIDE
deny tcp any host 10.184.116.108
permit tcp 172.15.0.0 0.0.255.255 10.162.0.0 0.0.255.255
permit tcp 172.16.0.0 0.0.255.255 10.162.0.0 0.0.255.255
In the Global Configuration mode apply the ACL with the ORIGINATED traffic to the WCCP Service 61, and the ACL with the RESPONSE traffic to the WCCP Service 62:
ip wccp 61 redirect-list OUR_SIDE2OTHER_SIDE group-list Cisco_WAES
ip wccp 62 redirect-list OTHER_SIDE2OUR_SIDE group-list Cisco_WAES
The last step is to apply the Service 61 to the SOURCE Interface and the Service 62 to the Response interface to your Network. Check the diagram, the pointed interfaces, and the commands below:
interface Fa0/1
ip wccp 61 redirect in
interface Fa0/24
ip wccp 61 redirect in
