In the exhibit, the 'Next hop type: Unusable' indicates that the BGP peer is not reachable through the IGP. For BGP to consider a route valid, the next hop must be reachable via the IGP. If the next hop is marked as unusable, it suggests that the necessary IGP routes to reach the BGP peer are missing or incorrect, leading to hidden routes. Therefore, the issue lies with the IGP reachability to the BGP peer.
Correct answer is B. Next hop is unusable due to no route in inet.3. Label information is screen is VPN labels.
Agreed, NH must be reachable via inet.3, and 17 seems to be vpn labels.
Correct answer seems to be "A", since the MPLS labels do exist.
"A" Is the Correct Answer.
Suppose MPLS is down then still BGP can receive and transmit VPNv4 Label/route to either side because IGP is making BGP to be in Establish state. And now if IGP is down then VPNv4 BGP Connection will not be be established. So, Correct answer is A.
The bgp session is established because the peer is reachable through the IGP then the correct answer is B.
