4- The tunnel between R1 and R3 is not coming up. Which two statements are true? (choose two) (Topology with a GRE tunnel and the outputs provided are show ip int brief and tunnel source and destination)" V, S `' @- T7 W8 X
A- tunnel source int Eth0/0 is down
, r# J& _: {' {5 o- j' x; yB- no route from R1 to R3 loopback0 (tunnel destination)! }6 K! p, ^; b4 |
answer: AB, w. s0 S% Z2 U7 V6 X! i

5- R1 and R2 OSPF neighbor. Which two statements are true? (choose two)
* p; W) N4 E& z- U; R(Output from show ip ospf neighbours on 2 routers, one of them shows FULL/DR, the other FULL/-, you need to know how were they configured and will they exchange routes)

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 adjacency dropped. What is the reason?
