Does WCCP support traffic from different VLANs(mapped to VRFs)?

diegorueda

Level 1

Hello,

I have the following scenario from the WAN to the Data Center and from the WAN to the Branch:

1. Router 2800/7200 with three (3) MPLS VRFs (VRF Lite)

2. Switch 3750 with three (3) WAN VLANs (one for each VRF) and three (3) LAN User Traffic VLANs (one for each ASA Context) and one WAE VLAN

3. WAE with WCCP enabled for one VLAN in the switch

4. ASA with three (3) Contexts

5. Three (3) Internal LANs (one for each Context)

In summary, there are three flows of traffic which are separated along the way from Branch to Data Center. WAEs are working for one VLAN(VRF1) and WCCP is enabled at the 3750 Switch to do the redirection (not in the router). The question is: does WCCP support traffic from different VLANs (similar to inline 802.1Q) and handle all three flows separate? If so, what should the configuration be at the switch and the WAE?

Thanks.

yes, at the 3750 you will need to place the redirect statement on each of the VLANs, ip wccp 61 redirect in

thank you Robert!!

The VRF awareness for 12.4(T) is still probably 8-12 months out. VRF aware WCCP features are definitely in the pipeline, but nothing has been publically published on availability timelines.

It's now publically available on the forum... but , I've only found it on the 3750 and 3550 documentation.

Kindly find here GRE Tunnel with VRF Configuration Example:

http://www.cisco.com/en/US/tech/tk436/tk428/technologies_configuration_example09186a00801e1294.shtml

I have gotten as far as the WAE registering the router:

"WCCP configuration for TCP Promiscuous service 61 and 62 succeeded.

WCCP configuration for TCP Promiscuous succeeded.Please remember to

configure WCCP service 61 and 62 on the corresponding router."

wae01#sh wccp router

Router Information for Service: TCP Promiscuous 61

Routers Configured and Seeing this Wide Area Engine(1)

Router Id Sent To Recv ID

0.0.0.0 209.1.1.1 0000022F

--------------------------

--------------------------

The router registers the WAE as a WCCP client:

router04#

"*Feb 4 18:56:09.892: %WCCP-5-SERVICEFOUND: Service 61 acquired on WCCP

client 209.1.1.2"

"*Feb 4 18:56:09.892: %WCCP-5-SERVICEFOUND: Service 62 acquired on WCCP

client 209.1.1.2"

The router however cannot figure out what its ID is and does not see

itself as a WCCP group router.

router04#sh ip wccp

Debugging should otherwise be similar to a regular switch or router.
