Two variations of this procedure can occur:
When the system does not allow assigning the same SID index or label to different routes of the same prefix within the same IGP instance, it resolves only one of them if they are received from another SR implementation and they are based on the RTM active route selection.
When the system does not allow assigning different SID indexes or labels to different routes of the same prefix within the same IGP instance, it resolves only one of them if they are received from another SR implementation and they are based on the RTM active route selection.
The selected SID is used for ECMP resolution to all neighbors. If the route is inter-area and the conflicting SIDs are advertised by different ABRs, ECMP toward all ABRs uses the selected SID.
The 7210 SAS-Mxp supports only LSR ECMP. It does not support LER ECMP.
