evpn-elan LB is not working as expected in SR path when knob 'protocols source-packet-routing inherit-label-nexthops’ is enabled in ptx10001-36mr running 23.4R2-S5.4-EVO
In 23.4, only flattened model is supported for evpn-elan. Knob 'protocols source-packet-routing inherit-label-nexthops' adds composite NH in underlay. That is not supported in 23.4. The support for expanded hierarchy for evpn-elan is added in 26.3. Please verify with 26.3 onwards image.
