Hi,

i see that for using generic gre i need to configure gre tunnle on the C6K.

is there another option for wccp redirection between WAE and C6k ?

ip forwarding will work if i am using 2 X C6K ?

Yes IP Forwarding will work.  However, make sure your routing is sound; meaning that it's not possible for traffic to hit a 61 or 62 redirect statement twice on the same local LAN effectively redirecting traffic to your WAE twice which would cause packet drops due to the WAE recognizing this as a routing loop (you would see syslog messages similar to this if this occurs... Feb 26 03:14:20 aus-waas-01 kernel: %WAAS-SYS-3-900000: 10.250.184.9:39618 -

10.249.250.127:445 - opt_syn_rcv: Routing Loop detected - Packet has our own
devid. Packet dropped.)

for that i need to use the "exclude" command.

i understand that ip forwarding is sending the packet to the DG. can i use HSRP as a default GW and configure the WAE to register to two wccp enabled routers (there physical ip address) ?

what about L2 redirect?, can i use that ?

do i need to configure something special at the C6K and the WAE ? (the wae is directly attached to the C6K's - same ip subnet)

thanks,

The exclude command is not required unless you use a redirect out statement or configure generic gre as the egress method.

Yes, if your WAE is directly attached to the 6K, point the default gw of the WAE to the HSRP address and the wccp router-list will be the two physical IPs of the 6500.

We would suggest you use l2-redirect and mask assignment, along with redirect in statements for 61 and 62 on your LAN and WAN facing L3 interfaces respectively.  This will allow you to take full advantage of the 6500 hardware to perform the redirection.

The only configuration required on the 6500 is to enable the 61 and 62 services globally, and place the redirect in statements on the appropriate L3 interfaces.

Thanks a lot.
