This is more of a theoretical question. Is there any way that a router can advertise its connected subnets without the interfaces needing to be up? I am using OSPF in this case.
I'll explain why I need this. When I configure a network for a customer and I send out the equipment I would then like to test if in a VPLS WAN the offices can ping each other. Yet, sometimes the customer takes a long time to connect anything to the "inside" LAN so I can't do that final test.
I could try to ping from one "inside" interface of one router to the other "inside" interface, but since there is nothing connected to it the routes to the networks are not advertised through OSPF.
Thanks in advance,
