Referring to the exhibit, Router-1 is attempting to form an EBGP session with Router-2. However, BGP routes are never exchanged between Router-1 and Router-2.
What is causing the problem?
A. The TCP-MSS value is set too low
B. The EXT group is not configured as an external type BGP peering session
C. The EBGP session is configured to use the wrong AS
D. The keep all statement is preventing the session from establishing
The answer is C.
There is no configuration for Router-2, so you cannot confirm that R2’s peer-as is 5 in their EBGP group pointed to R1.
AS1 is for R1, not R5! Probably – C
the session type can be omitted — not B.
I mean “not AS5 “
You are absolutley correct, the answer should be C. In Junos the automatic group type is external, so that wouldn’t be a problem.
