So, I build two GRE on the Loopback interfaces, - If Il use OSPF into the GRE, and define OSPF adjacence between tunnel interfaces , there is no need to activate keepalives, the faillures will be detected by OSPF process and will converge ( may be a little more slowly) ?
- In this case , I need to activate 2 or 4 GRE ? to deal with each failure case ?
