A network engineer enables OSPF on a Frame Relay WAN connection to various remote sites, but no OSPF adjacencies come up.
Which two actions are possible solutions for this issue? (Choose Two)
A. Change the network type to point-to-multipoint under WAN interface.
B. Enable virtual links.
C. Change the network type to nonbroadcast multipoint access.
D. Configure the neighbor command under OSPF process for each remote site.
E. Ensure that the OSPF process number matches among all remote sites
A,D is correct as it is about TWO possible solutions.
First Solution
A) Changing the network type to “point-to-multipoint” -> allows Dynamic Discovery of Neighbors. No Neighbor command is necessary.
Second Solution:
D) “Nonbroadcast” (NBMA) is the default interface type on Frame Relay physical and multipoint subinterfaces -> does not allow Dynamic Discovery of Neighbors. Therefore the neighor command must be used.
I think there is something wrong with this question as (A,D) choices can’t work together .. if you configured the interface type as point-to-multipoint u can’t configure the neighbors manually with neighor command .. this configuration will be refused by the router ..
so ..
i think we should select (C,D) assuming that the word “multipoint ” in (C) choice is mistyped in the dump and it will be “multiple” in the real exam
Yes True. If network type is Point-to-Multi point, neighbors will discover dynamically and no need to configure manually.
if network type is non-broadcast Multi Access, we have to configure neighbors manually.
