The municipal NOC’s DCI dashboard must prove the remote DC gateway is still exchanging EVPN with the local border. What should operators monitor first?
Select an answer to reveal the explanation.
Short Explanation
If the EVPN peer to the far gateway drops, the overlay phone line is dead even if the dark fiber still lights up. Watch BGP EVPN session state and route activity between DCI borders first. Optics matter too—but they are not the overlay control-plane check.
Full Explanation
Monitoring DCI includes verifying Multiprotocol BGP EVPN sessions between interconnect gateways and confirming expected EVPN route exchange. Optical levels and underlay metrics are useful but incomplete alone. Access VLAN counts and ZTP DHCP pools are unrelated as the primary EVPN DCI health signal.
