Refer to the Exhibit.
Referring to the exhibit, you must advertise the 18.104.22.168/16 routes from Site 2 to Site 1, but R3
is not currently advertising any BGP routes to R2.
Why is this happening?
The IBGP routes are not active and EBGP will advertise only active routes.
The IBGP routes are not active because the next hop is not reachable.
The IBGP routes will not be advertised because the AS path shows incomplete.
The IBGP routes will not be advertised because you must use a policy to advertise IBGP
