You are experiencing an issue bringing up an aggregated Ethernet interface between a spine and a leaf. Referring to the exhibit, what is the issue?
Junos LACP is passive by default when no active or passive mode is explicitly configured. A passive LACP peer only responds to received LACP PDUs; therefore, with both ends passive, neither end initiates negotiation and the aggregated Ethernet bundle does not come up. Configure active under aggregated-ether-options lacp on at least one side.
