Hi @Ibrahim Jamil 

L3OUT Q
Based on  pages 57 and 58 of Cisco Live BRKDCN-2949 document which you can find it on this link (https://www.ciscolive.com/c/dam/r/ciscolive/global-event/docs/2023/pdf/BRKDCN-2949.pdf)

Local L3Outs preferred over L3Outs in remote pods

Remote pod L3Out may be used if it has a better external metric

Also You will find it useful (Pages 67-68)
