18.3.1Configuring Site to Site Tunnel
To configure GRE in a site to site tunnel configuration:
Step 1: Configure the interface.
Blackbox> configure terminal Blackbox/configure> interface bundle wan1 Blackbox/configure/interface/bundle wan1> link t1 1 Blackbox/configure/interface/bundle wan1> encapsulation ppp Blackbox/configure/interface/bundle wan1> ip address 192.168.94.220 255.255.255.0
Blackbox/configure/interface/bundle wan1> exit
Step 2: Configure the tunnel.
Blackbox/configure> interface tunnel t0 Blackbox/configure/interface/tunnel t0> ip 103.1.1.2 24 Blackbox/configure/interface/tunnel t0> tunnel source 192.168.94.220 Blackbox/configure/interface/tunnel t0> tunnel destination 192.168.55.75
Blackbox/configure/interface/tunnel t0> exit
Step 3: Configure the IP routes.
Blackbox/configure> ip route 0.0.0.0 0.0.0.0 192.168.94.254
Blackbox/configure> ip route 40.1.1.0 24 t0
