So we have network A:
network 10.0.1.0
netmask 255.255.255.0
router 10.0.1.1
Internet 172.16.17.18
and network B:
network 10.0.2.0
netmask 255.255.255.0
router 10.0.2.1
Internet 172.19.20.21
On the router of network A, you do the following:
ip tunnel add B mode gre remote 172.19.20.21 local 172.16.17.18 ttl 255
ip addr add 10.0.1.1 dev B
ip link set B up
ip link set B mtu 1514
ip route add 10.0.2.0/24 dev B
let’s go on with the router of the network B
ip tunnel add A mode gre remote 172.16.17.18 local 172.19.20.21 ttl 255
ip addr add 10.0.2.1 dev A
ip link set A up
ip link set A mtu 1514
ip route add 10.0.1.0/24 dev A
If you want to delete the tunnel.
ip link set B down
ip tunnel del B
Of course, you can replace B with A for the A router
