Ops sees the same MAC advertised from conflicting Ethernet Segment locations and suspects a learning conflict. What awareness should the engineer apply?
Select an answer to reveal the explanation.
Short Explanation
Two places claiming the same MAC is a municipal double-booking — investigate ESI mistakes or loops, do not shrug. Disabling add-path, wiping OSPF, or merging all VNIs does not fix a duplicate-MAC conflict.
Full Explanation
EVPN can surface duplicate MAC advertisements when the same address is learned from inconsistent ESIs or looping paths. Operators should detect and remediate conflicts (ESI, cabling, mobility anomalies), not disable multipath features globally, clear unrelated underlay databases, or collapse VNIs into one.
