Redirection on GRE tunnels

[shiravani]

I have implemented WCCP redirect on a serial interface I have. I also have a GRE tunnel interface sourced from that same serial interface.I would like to know the IOS order of operation for that GRE tunnel interface in regards to redirection. Do I have to specifically configure the "ip wccp redirect" command on the tunnel interafce or the command on the underlying serial interface would suffice?

Hello Shiravani,

You need to configure the "ip wccp redirect " on the GRE tunnel interface itself and not the serial interface ( if you want to redirect traffic coming out from the GRE tunnel ).

The IOS order does not really apply on this case,the GRE tunnel is just like any other interface.( GRE/ipsec packets are handled by physical (WAN) interface.)

I  also suggest to do a lab if any doubts or further questions before you making the changes.

Hope this helps!
