The correct answer is A. Configure multisite DCI-tracking on interface Eth1/18. The EVPN Multisite gateway‐IF (loopback10) is going down because the router‐based DCI path isn't being tracked by Multisite. You must enable DCI-tracking on the leaf's DCI link so the control plane knows when the inter-site underlay is up. In this topology the DCI interface on…

Explanation

The EVPN Multisite gateway‐IF (loopback10) is going down because the router‐based DCI path isn't being tracked by Multisite. You must enable DCI-tracking on the leaf's DCI link so the control plane knows when the inter-site underlay is up. In this topology the DCI interface on the secondary side is Ethernet1/18, so: Leaf3(config)# interface ethernet1/18 Leaf3(config-if)# evpn multisite dci-tracking Once DCI-tracking is enabled, the Multisite VIP (and thus VLAN 10) will come up at the
