You are troubleshooting an L3VPN that is part of an EVPN/MPLS DCI. You notice that the EVPN overlay BGP session toward 10.29.50.4 is unable to establish. Why is the BGP session failing to establish?
Refer to the exhibit. Referring to the exhibit, which two statements are correct? (Choose two.)
Which two statements about a DHCP relay in an EVPN-VXLAN fabric are correct? (Choose two.)
Which two statements are true Virtual Chassis? (Choose two.)
Which two combinations are supported when configuring a Virtual Chassis Fabric? (Choose two.)
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 asked to enable plug-and-play line card switches in an active VCF without making any future Junos configuration charges. You are also required to ensure that all new line card are automatically upgrade to the correct Junos version without any manual intervention. In this scenario, which two actions will accomplish this task? (Choose two.)

You want to improve network convergence within a data center during link failures. In this scenario, which EVPN-VXLAN feature will accomplish this task?

A.
storm control
Answers
A.
storm control
B.
Ethernet segment auto discovery
Answers
B.
Ethernet segment auto discovery
C.
MAC filtering
Answers
C.
MAC filtering
D.
MAC mass withdrawal
Answers
D.
MAC mass withdrawal
Suggested answer: D

Explanation:

The MAC mass withdrawal feature in EVPN-VXLAN environments significantly improves network convergence during link failures. When a link failure occurs, instead of individually withdrawing each MAC address learned on the failed link, EVPN can send a single, consolidated message indicating that all MAC addresses associated with the Ethernet Segment Identifier (ESI) of the failed link are no longer reachable. This accelerates the convergence process by reducing the amount of control plane traffic needed to update the network state.
