Which protocol is used between VCF member devices to create a loop-free topology?
Referring to the exhibit, each node in the IP fabric is peering to its directly attached neighbor using EBGP. Each node is peering using physical interface IP addresses. Leaf 2 and Leaf 3 are advertising the 10.1.1/24 network into EBGP. Spine 2 must be configured so that it can load- share traffic destined to the 10 1.1/24 network over both next-hop A and next-hop B. Which two actions must be performed to accomplish this task? (Choose two.)

You are configuring a DCI VPN solution between sites that require an L3VPN to work with your EVPN deployment. Your organization's policy restricts configuring RSVP and LDP on your WAN links. While configuring the solution, you notice that no routes exist in the inet table. In this scenario, which parameter will solve this problem?

D.
bgp family evpn signaling
Suggested answer: A

Explanation:

In a scenario where RSVP and LDP are restricted, and routes are not appearing in the inet table, the use of 'bgp family inet labeled-unicast per-group-label' becomes necessary. This setting is crucial in environments where label distribution protocols like RSVP or LDP are not used. It enables the use of MPLS labels in BGP without relying on these protocols, which is essential for integrating L3VPN with EVPN over WAN links that do not support RSVP or LDP. The ''per-group-label'' option ensures that a single label is used for all routes exchanged with a BGP neighbor, which simplifies label management and conserves label space.
