Hello all,
Thanks for all the advices on how to set up tunneling for ospf. In my test network, I used a switch to simulate a WAN sitting in between the two routers. I can ping every node on ospf networks without setting up static route in the routers and I guess that because the tunneling IP addresses are in the same subnet and they both connected to the switch. Should I connect to a WAN that I have no administrative privilege over, do I need to set up static route in the routers so that they would know which WAN gateways to use (i.e. 192.x.x.152 and 142.x.x.152 are interfaces of the WAN entry points for routers 4 and 5 respectively)? What should the ip routes be? Here're current config files:
hostname Router4
