Hello all,

i've been trying to install WAAS appliance, unfortunately in the one end of the connection i am terminating the WAAS VLAN on a VRF interface and it seems the there are no WCCP redirects to the WAAS. Then removed the vrf just to test and i saw WCCP redirects, but then i loose connection to the WAAS manager.

Has anyone dealed with such a deployment.

I have searched quickly in the net but no clear answer occured.

Anyway i will be more than thankfull for any advice

Hi Teodor,

wccp isn't support on vrf at this moment.

I you must have a directly connected interface in which make wccp redirection.

bye

Hi Marco,

thanks a lot, this will save some effort.

I will find clear interfaces for the redirection.

HI Teodor,


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.

It would require a Nexus 7K or 77K though ;-)
