WCCP and VRF

I am struggling to see a clear statement of VRF awareness for WCCP in 12.4(T). I have seen comments on here that WCCP is not VRF aware, but the documentation for 12.4(T) makes no reference to VRF awareness. Does anyone know if WCCP is VRF aware yet, and just as importantly, has anyone got a reference we can point people to?

Thanks,

Paul

Re: WCCP and VRF

Paul,

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.

Thanks,

Dan

Re: WCCP and VRF

Dan, thanks for the reply - are you aware of any references that say WCCP isn't VRF aware? I found one but it was platform specific for the 3750.

Re: WCCP and VRF

Paul,

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

Thanks,

Dan

Re: WCCP and VRF

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

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.
