Managing Generic Routing Encapsulation Tunnels
RUGGEDCOM ROX II can employ the Generic Routing Encapsulation (GRE) protocol to encapsulate multicast traffic
and IPv6 packets together and transport them through an IPv4 network tunnel. As such, GRE tunnels can transport
traffic through any number of intermediate networks.
The key parameters for GRE tunnels is the tunnel name, local router address, remote router address and remote
subnet.
The following illustrates a typical GRE tunnel configuration:
192.168.2.1
192.168.2.0/24
172.19.20.21

eth2 192.168.1.1 eth1
