I'm in process to connect two or more Provider Edge router using GRE/IPIP
tunnels. What were your experiences? If the answer is yes than I would love
to ask how do you connect a PE to another PE using the GRE/IPIP tunnel
interfaces. Keeping in mind that I'm going to carry multiple customers
If you don't have mpls then using GRE between PEs would be okay.
Do some thing like:
int tun1
ip address 1.1.1.1
tunnel source x.x.x.x
tunnel dest y.y.y.y
y.y.y.y is the other PE backbone facing ip, reachable by x.x.x.x
then advertise your loopback address through the tunnel using whatever you
