I've inherited a network made up of Mikrotik routers of various models, approx 20. The network design is made up of a number of /24's with ALL routers having an IP on one or more of the /24's. All routes are Static. My goal is to redesign the network so that I have /30's between my hops and a Routing Protocol in place. So to aid me I want to build a new "routed" network over the top and slowly dismantle the current /24 static network. So can you clear up a few questions I have? It's my understanding that OSPF requires the same MTU on both facing interfaces. Also, I'm looking at one router (RT2) that actually bridges all interfaces traffic. I've got OSPF set up on this (RT2) and the edge router (RT1). I see the neighbor from the edge (RT1), but not the edge (RT1) as a neighbor on RT2. Could use some assistance.
Thanks so much...
