How to configure the router using Expand box?

[rgbatucan]

I need help on configuring the Cisco routers.
Here's the scenario...

I want to compress as much all packets COMING IN to our network to optimize the bandwidth. When users from Lan accessing the internet, it goes out to our GW1 but I want the RETURN internet packets will go first to Expand 2 for compression then goes to Expand1 for decompression. Please see attached network diagram setup. All Expand appliances are already configured. Thanks.

What configuration should be in GW1 and R2, both C2851?

Good afternoon Restie,

I'm afraid I'm not familiar with these Expand boxes, but, based on what you described, I would assume that they are able to run WCCP. If that is the case, it would probably be the easiest way to get the redirection done.

Your topology is essentially the same one used by WAAS, so, I would recommend you to have a look at the WCCP configuration section of the WAAS documentation (http://www.cisco.com/en/US/docs/app_ntwk_services/waas/waas/v431/configuration/guide/traffic.html). You will just need to adapt the commands to the WCCP service numbers used by the Expand boxes.

If WCCP is not possible, then you can achieve the same using Policy-based-routing. You would need to define two ACL (one for each direction) and then change the next hop to be the Expand box for traffic matching those ACL.

Please, let me know if you need further details on any of the two alternatives

Hi Daniel,

I configure it as PBR so that all www traffic will be pass to that tunnel. I want all www traffic from Area 1 to Area 2 (vice versa) will pass to IPComp Tunnel (see diagram below). I configure a policy based routing in each router. Did I miss something in router configuration? Did I apply the PBR in right interfaces? How can I configure also the returned www traffic in Router 2? I really appreciate for any response. Thank you.

ROUTER 1

interface GigabitEthernet0/0
  ip policy route-map EXPAND_AREA1

route-map EXPAND_AREA1 permit 10
  description IPCOM TUNNEL TO AREA2
  match ip address EXPAND_ACL
  set ip next-hop A.A.A.2

ip access-list extended EXPAND_ACL
  remark PACKETS THAT PASSES TO IPC TUNNEL
  permit tcp any any eq www

========================================

ROUTER 2

interface GigabitEthernet0/0
  ip policy route-map EXPAND_AREA2

route-map EXPAND_AREA2 permit 10
  description IPCOM TUNNEL TO AREA1
  match ip address EXPAND_ACL
  set ip next-hop D.D.D.2

ip access-list extended EXPAND_ACL
  remark PACKETS THAT PASSES TO IPC TUNNEL
  permit tcp any any eq www

Hi Restie,

As I mentioned, I am not aware of how the Expand boxes are working, so I don't know the redirection requirements.

I would suggest you to contact the Expand support team to get some further information on the suggested topologies.

Regards

I made this setups work already three weeks ago.

AREA 1:

Configure PBR, IP SLA, ACL

AREA 2:

Configure NAT, PBR, ACL
