Which two statements are true about the OSPF adjacency displayed in the exhibit? (Choose two.)
A.
There is a mismatch in the dead interval parameter between routers R1 and R2.
B.
There is a mismatch in the hold timer parameter between routers R1 and R2.
C.
There is a mismatch in the hello interval parameter between routers R1 and R2.
D.
There is a mismatch in the poll interval parameter between routers R1 and R2.
Explanation:
If the timers are equal, which they are by default in JUNOS (for LAN/P2P the Hello = 10s and Dead = 40s), the
neighbors will establish a relationship (at least on 1 side).
There is a Hello and Dead parameter mismatch. On R1 we see:
On R1 we see:
