A multihomed Ethernet Segment shows an unexpected Designated Forwarder on city leaf peers. What should troubleshooting examine first at professional depth?
Select an answer to reveal the explanation.
Short Explanation
Weird DF? Check the ESI wiring and election settings on that multihomed segment — that is who wins the forwarding badge. Underlay IGP choice is not the DF referee, and deleting Type-2s or killing EVPN is not troubleshooting.
Full Explanation
For EVPN multihoming, Designated Forwarder election is driven by Ethernet Segment Identifier configuration and DF election procedures among PE/VTEPs on that ES. Unexpected DF results warrant verifying ESI consistency, election timers/preferences, and related Type-4/ES signaling. Underlay protocol choice alone does not elect the DF; removing Type-2 or permanently disabling EVPN on a peer is not a correct fix.
