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?



I have this problem too.

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.

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.

It's now publically available on the forum... but you are correct, 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:


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 0000022F



The router registers the WAE as a WCCP client:


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


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


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

itself as a WCCP group router.

router04#sh ip wccp

This is a short summary of important commands for working with VRF's.

View the VRF instances and the associated interfaces.

ml-mr-c6-gs#show ip vrf

Name Default RD Interfaces

blurvrf 100:2 Vlan215


tgvrf 100:1 Vlan132




Show the routing table for a specific VRF.

ml-mr-c6-gs#show ip route vrf tgvrf

Routing Table: tgvrf

Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP

D - EIGRP, EX - EIGRP external,


Gateway of last resort is to network

O E2 [110/1] via, 1d19h, Vlan325

O E2 [110/160] via, 1d19h, Vlan325 is subnetted, 3 subnets

O E2 [110/0] via, 1d19h, Vlan325

O E2 [110/1] via, 1d19h, Vlan325

O E2 [110/1] via, 1d19h, Vlan325


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