The GRE tunnel will be used to route traffic between the 192.168.1.0/24 and 172.16.1.0/24 networks. Follow the steps below to configure the GRE tunnel on both routers: CLI: Access the Command Line Interface on ER-L.You can do this using the CLI button in the GUI or by using a program such as PuTTY.
GRE/IPsec (or IPIP/IPsec, SIT/IPsec, or any other stateless tunnel protocol over IPsec) is the usual way to protect the traffic inside a tunnel.. An advantage of this scheme is that you get a real interface with its own address, which makes it easier to setup static routes or use dynamic routing protocols without having to modify IPsec policies.

Multicast traffic forwarding – GRE tunnels can be used to forward multicast traffic, whereas a VPN cannot. Because of this, multicast traffic such as advertisements sent by routing protocols can be easily transferred between remote sites when using a GRE tunnel.
