Arjun,

The source address of the tunnel interface on Pune should be the fa0/0 address 10.5.2.90 rather than 10.5.2.89.

Do you have a route on Mumbai to reach 10.5.2.90 ans inversely a route on Pune to reach 10.5.2.2.

Also, you do not need the static routes for 10.10.1.0/30 as these routes will be installed as a connected routes because of the tunnel interface.

Thanx...

I'll Try and revert.

Thanx a Lot..

Now i am able to ping my remote tunnel IP.I have one more query.

I have one more backup ISP to Pune using BGP.I want redundancy.If my 1st ISP fail, 2nd will work.

can I create a second tunnel for that.

Currently for 1st ISP i am using static route.Is it possible to use same loopback address for both ISP.

I am very greatful to U.

Hi..

Any suggestion..

Arjun,

Could you please explain why you would need a GRE tunnel to your primary or backup ISP.

Thanx...

I need autofailover to my both ISP.

Pune user should access Mumbai via 2nd ISP if my 1st ISP fail.

Thax Again..

Arjun,

And why do you need GRE tunnels to do that? Can't you do it without GRE? A diagram might be useful.

Thanx a lot..

I can do this without GRE.

My priority is Autofailover to my both ISP.For REL(MPLS VPN) i am using BGP and for VSNL (MPLS VPN) using static routes on my Mumbai router.

On Pune router i am using static routes for primary (REL).When REL down i manually change that routes toward VSNL.

Is there any way to autoswitchover route like using metric.

Pls find the attachment.

You can use conditional advertisemsnt on the router that is running BGP. Please check out "neighbor advertise-map non-exist-map"

Thax for u'r suggestion..

But on pune router i am not using BGP.There is a static route for ISP.

Is there any way..?
