@Hellboy: It’s a “select 2 out of 5” type of question and i selected that the router that shows as FULL/- is point to point and that the other router won’t send routing updates.8 w* X. K. w; U8 d

Q6-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 adjacency dropped. What is the reason?. W8 ]7 I# A) |# m1 T
(The cause of OSPF forming an adjacency over a GRE tunnel and dropping immediately)
