Sorry for the off topic, but I need some opinions.
I have multiple gre tunnels between sites and I use ipsec to encrypt traffic over them. When I need something encrypted, I point a static route to the tunnel interfaces.
Works great, however, the ipsec sa expires after 24 hour, and there is s slight delay upon re-establishment of the ipsec ike sa. I need the ipsec sa to be permenantly established.
 Should I run a routing protocol between the tunnel interfaces? Any other ideas will be appreciate.

Thanks,
