WebWhile IPsec can protect unicast IP traffic,OSPF communicates through IP multicasts. Therefore, all traffic between Routers R1 and R2 (including the OSPF multicasts) is encapsulated inside of a GRE tunnel. Those GRE packets, which are unicast IP packets, are then sent across, and protected by, an IPsec tunnel." WebIPSec is configured on the ASA (which works fine) and the GRE Tunnel terminates on the router behind. The tunnel is up/up but there is no traffic going through it. Wireshark captures show that GRE packets arrive at the ASA on the inside interface but dont leave on the outside interface. I permit all traffic from inside as well from the outside.
