Please refer to attached frame relay network diagram and associated router configs.
The 4 routers are interconnected with hub-and-spoke PVCs with R4 as the hub router. All config is done at physical interfaces (no subinterfaces). I disabled FR Inverse ARP and configured static maps, in a full-mesh fashion. i.e. all 4 routers can ping to each others' serial interface IP addresses.
(1) For spoke routers, what's the difference if the "frame-relay map" statements to other spokes contain the "broadcast" keyword and without the "broadcast" keyword. I believe it has something to do with the routing protocol we gonna run on the FR network.
(2) Given my configurations with so-called full-mesh static maps between routers, how does it affect routing protocol neighbor adjacencies? For e.g. EIGRP, are adjacencies formed between R4-R2, R4-R5 & R4-R6 or any-to-any kind of adjacencies, just like in LAN environment?
One other thing to remember is: since configuration is done on the major/physical interface, I believe you'd also have to disable split horizon, otherwise the hub router will not advertise EIGRP-learned routes from one spoke router to other spokes.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
