can I shutdown interface by configuration?

[julxu]

Hi

I have a case, as below:

                local <-> vpn<-> remote.

There is a policy if vpn<->remote down, than traffic go to backup link. I want cover the local<-> vpn part, so, is any possible to lte me do:

if local<-> vpn down

than

     shut vpn interface

fi

If not possible, what is a possible solution to cover local<->vpn?

I use asr1000 as router to link local, vpn and remote.

Any comments will be apprecaited

Thanks in advance

Is this a site to site VPN?  If so use VTI interfaces (GRE over IPSec) and run a dynamic routing protocol over the whole lot.
