WCCP between WAE674 and ASR1000

[Peter Kim]

I'm having an issue setting up wccp between WAE674 and ASR1000.  When I run "show wccp router" from WAE, router is not recognized as one that is configured and seeing by WAE.  I can ping the router from WAE.

WAE674 - 4.1.1d.7

ASR1000 - 15.0(1)S2

WAE was registered with Central-Manager...  It is just not talking to ASR that is directly connected.

Any suggestion will be really appreciated.

Thanks.

Peter,

Can you post your ASR's configuration (scub the IP's and any other sesative information).  Since I'm not sure what you've tried so far have you ensured your setup meets the following:

Prerequisites for WCCP

   1) To use WCCP, IP must be configured on the interface connected to the Internet and another interface must be connected to the content engine.
   2) The interface connected to the content engine must be a Fast Ethernet or Gigabit Ethernet interface.

Restrictions for WCCP

    WCCP works only with IPv4 networks.
    WCCP does not redirect IP multicast packets.
    WCCP packet redirection on outbound interfaces is not supported in XE releases prior to XE Release 3.1S
    There is no SNMP support and no MIB has been implemented for WCCPv2.
    Cisco ASR 1000 Series Routers do not support WCCPv1.
    Cisco ASR 1000 Series Routers do not support inter-VRF redirection.
    Service groups can comprise up to 32 content engines and 32 routers.
    WCCP does not support In-Service Software Upgrade (ISSU), Stateful Switchover (SSO) or Nonstop Forwarding (NSF).
    Transiting packets are lost in the event of a forwarding processor (FP) failover on a 6-rack-unit (6RU) and 13RU chassis.
    All content engines in a cluster must be configured to communicate with all routers servicing the cluster.
    Hash assignment as a load-balancing method for a WCCP service is not supported. As of Cisco IOS XE Release 3.1S, clients that send Hash assignment will not be allowed to come online by the router. On Cisco ASR 1000 Series Routers, the show ip wccp 61 detail command displays that Hash is an incompatible assignment method.
    For routers servicing a multicast cluster, the Time To Live (TTL) value must be set at 15 or fewer.
    The show ip wccp command displays information about software-based (process, fast and Cisco Express Forwarding [CEF]) forwarding of WCCP packets. The Cisco ASR 1000 Series Routers implement WCCP in hardware, rather than in the CEF or process-switching paths. Implementing WCCP in hardware results in a packet count of 0 when the show ip wccp command is entered. Use the show platform software wccp interface countersor show platform software wccp counterscommands to display global statistics related to WCCP on the Cisco ASR 1000 Series Routers.

Also,

What wccp services are you looking to redirect?  Is this to support WAAS?  If so you need to enable ip wccp 61 and 62 services on the ASR, but if this is for ACNS web caching/ streaming media proxy there are other services that will need to be enabled.

Thanks for your reply.  I'm fairly new to WCCP.

This is what we are trying to do.  We have two sites with private DS3 running GRE over IPSEC.  Since replication traffic is taking most of BW, I'm trying to put WAE in between see if this will help at all.  I was going through lots of different documents and followed the instruction.  It just doesn't work.  I must have missed something in configuration.  I have one already setup between WAE674 and 7609 router.  It works fine.  It has to be with configuration on ASR.

WAE G1/0 - ASR 1006 G0/3/4

On ASR,

ip wccp 61

ip wccp 62

Under interface,

ip wccp 61 redirect in

ip wccp 62 redirect in

Let me know if you need anything else.

Thanks.
