Hi,
Two queries:
What happens when power fails on the ISRG2 router with WAAS running? Does the WAAS recovers on its own once the power is back up or it needs manual intervention?
What happens to WCCP interception if the SRE module fails , does it use fail to wire and pass through all traffic?
Currently in design phase, we intend to use WAAS 4.5.1 firmware SRE 710 and 910 on ISR 2911 in this project.
Thanks

Hi Suja,
The SRE module will boot automatically after power is restored to the router.
As for WCCP, there are periodic keepalive messages sent between the WAE and the WCCP redirecting router, after the module goes down, the router will detect it and stop redirecting traffic to. When that happens, due to the WAAS modifications to the connections, all the connections will be reset by the server and will have to be re-established.

Thanks Dan
Can we alter the reset interval to the reduce the downtime.
A failover query this time:
For a Layer 3 link between Datacentre's what would be the best option ?A separate subnet for WAAS in the core or shared.
We have to test failover, won't the traffic take an unoptimised path during failover , since there is no layer 2 between the DC's
Appreciate your time
Thanks

Hi Suja,
I'm afraid I don't understand your questions. Can you please be more specific?
