WCCP in a VRF environment

Hi Everyone,

I'm not sure if this is the right place to post this, however, I'm trying to get wccp working in a vrf environment.

I am currently using squid/wccp an outbound proxy server. If I place squid outside of the vrf environment (external network), it work great.

I change the ip of the squid server to place it on the internal network (part of the vrf), wccp will not establish a connection with the router...

This is the same router for both internal and external networks. Is this there a way around this.

Thanks..

Re: WCCP in a VRF environment

Dominique,

I hate to say that WCCP is not VRF Aware. So, you will not be able to make WCCP work in VRF Environment.

I am sure that this is not what you wanted to hear.

Regards,

Arul

Re: WCCP in a VRF environment

Hi Dominique,

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.

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.
