You administer an EVPN-VXLAN fabric. You notice that there is no VXLAN traffic forwarding through the network.

Referring to the exhibit, which modification will solve the problem?

set interfaces et-0/0/49 unit 0 family vxlan

set firewall family inet filter allow-BGP term 1 from protocol tcp set firewall family inet filter allow-BGP term 1 from destination-port 4789

set interfaces et-0/0/49 unit 0 family vpls

set firewall family inet filter allow-BGP term 1 from protocol udp set firewall family inet filter allow-BGP term 1 from destination-port 4789

VXLAN traffic uses UDP port 4789 for communication. To enable VXLAN traffic forwarding, the firewall filter should be modified to allow UDP traffic on port 4789. Therefore, the correct modification is to set the firewall to filter for UDP protocol and destination port 4789.
