Here is the requirement:

I  have three locations(A,B,C).. Now I looking tunnel redundency.

A -- B one tunnel(this should be always primary)

A - C on tunnel(This should be always secodary)

If the primary is down tunnel traffic should switchover to secondary and again it shld switchover to primary once it back on opertional..

I looking for configuration example..

I don't get it, you have 3 locations, but you are saying one tunnel from A to B and one from A to C, but then you just have two seperate tunnels to two different sites ?

Thanks for your immediate response

We have a  back to back connectivty B to C....

If A wants to access application @ C, first A will land @ B and access the applications @ C thru back to bakc connectivity. here is the flow

A-B - C

If A- B is down, then A will land on C and will access the B thru back to is the flow


Bit confusion will be there as design is like that....

One more question can I run GRE tunnel on ASA/PIX?

GRE tunnels are not supported on the ASA to my knowledge.

What routing protocol are you using?  I found an example of how to pass OSPF traffic over an IPSEC tunnel with the ASA.

If you are running a routing protocol like OSPF, when if one of your sites goes down you and have your traffic flow roll over to the other site.
