Configuring the GRE Tunnel Interface on Router PE1

Configure the GRE tunnel interface on Router PE1:



[edit interfaces gr-1/2/0]
unit 0 {


tunnel {
source 192.168.197.249;
destination 192.168.197.250;
}




family inet {
address 10.49.2.2/30;
}


}

In this example, interface t3-0/1/3 acts as the encapsulating interface for the GRE tunnel.
