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