Hi Everyone!
We have two routers configured with GRE tunnel and have established the connection between two routers. but non of the routers cant ping internal subnet ips from each side. all the routes are learned from each routers and filled with routing table but still no access. both routers running BGP along with the GRE tunnel. I only configured GRE Tunnel and assigned LAN subnet to bridge interface/nat rule as masquerade/BGP with internal IP subnet so other router will learn. GRE is established. Other than what I configured, are there any other configs to be made to make the internal ips connectivity.
When a traceroute performed from one router to other router's internal ip address, routing fails from other routers GRE interface.
Please refer to below script from client router
/interface bridge

Please help me to solve this issue!
Thanks in advance!
