Answer: B e ???
& r( t* R6 }+ F/ q9 BNote:
@Tamelir: This is the case when router has configured network that selects DR – broadcast,
2 B/ c( k! b- T2 h2 sNBMA, while the other’s network is p2p, p2mp or p2mp p2mp-nb WITH PRIORITY LARGER THAN THE FIRST ROUTER.
5 J+ B' a9 e) L6 _6 _" _The routers WON’T EXCHANGE routes.
' Q- p( R# Z! e$ L! B2 k! K4 e! w3 r@Hellboy: It’s a “select 2 out of 5” type of question and i selected that the router that
- Q6 E# ~2 T4 I" ~5 z: Q" L; {shows as FULL/- is point to point and that the other router won’t send routing updates.

6- Two routers are connected through PPP connection. After the PPP was established
the admin put OSPF running above it. The OSPF formed adjacency but after soon the
" h9 _& @+ A& t+ Nadjacency dropped. What is the reason?
(The cause of OSPF forming an adjacency over a GRE tunnel and dropping immediately)
# M" S- ?- ]- i0 CA- MTU mismatch
0 w8 J, w6 \+ Q/ ]B- ospf routes contains the route to tunnel destination ( right)
: D/ x: h6 ^  uC-Gre tunnel destination is not reachable through tunnel
>>> if this statement removes “not” then this would probably be the answer,
because the tunnel destination can not be through the tunnel itself,
4 ~2 G- g' A9 B9 u2 @" ]8 c& Rotherwise would cause Recursive Routing.
3 D5 x4 Z% d0 c  Y( nD-Gre tunnel ip address must be covered by network under “router ospf 1”
5 f/ e! }9 P! `: b* u3 ?3 }4 S/ a>>> The Tunnel IP subnet needs to be added to the routing process,
add network under router ospf x >>> So this one should be the right answer.
Answer: D ???
someone suggested the following answer but it is not matching the uptions above:
OSPF is configured on the tunnel , and the issue is bcoz the tunnel destination routes thru the tunnel
