This example shows how the GRE tunnel feature could be configured.
configure default del port all create vlan inet configure vlan inet add port 24 configure vlan inet ipa 1.1.1.1/24 create vlan users configure vlan users add port 1 configure vlan users ipa 100.0.0.1/24 create tunnel mytunnel gre destination 1.1.1.2 source 1.1.1.1 configure tunnel "mytunnel" ipaddress 2.0.0.1/24 configure iproute add 200.0.0.0/24 2.0.0.2 enable ipforwarding
unconfigure switch all configure default del port all create vlan inet configure vlan inet add port 10:1 configure vlan inet ipa 1.1.1.2/24 create vlan users configure vlan users add port 10:2 configure vlan users ipa 200.0.0.1/24 create tunnel mytunnel gre destination 1.1.1.1 source 1.1.1.2 configure tunnel "mytunnel" ipaddress 2.0.0.2/24 configure iproute add 100.0.0.0/24 2.0.0.1 enable ipforwarding
