We are configuring GRE-IPsec with OSPF. Without IPSEC configuration we are able to form OSPF neighbor realtionship across the two end of GRE tunnel. But when we apply "crypto map NAP" to tunnel interface OSPF is not getting formed.
Here is the configuration and similar configuration is on the other end ot the TUNNEL.
int tunnel 10
ip add 10.1.1.1
tunnel source s0/0
tunnel destination 10.2.1.2
crypto map NAP //** Crypto MAP applied **//
ip add 10.2.1.1 255.255.255.2.252
ip add 10.3.1.1 255.255.255.0
router ospf 10
network 10.3.1.0 0.0.0.255 a 0 // *** Ethernet subnet published ***//
network 10.1.1.0 0.0.0.255 a 0 // *** Tunnel subnet published ***//
