Description (partial)

This defect is not applicable to current GBR release since vxlan configs were not a part of the previous release which is freetown. Hence there is no issue on issu.

There exists an issue with vxlan peer learning on ISSU from gbr to gbr upgrade. When a line card upgrade is in progress and the SUP is already up and ready to learn peers, line card components reject a peer-add and we end up having inconsistent peer information in PI components and line card which causes an issue when the peer needs to be re-learned. 

This issue is not currently applicable to gbr since freetown -> gbr ISSU will not suffer from this because vxlan wil be first introduced in gbr.

Occurs only during ISSU.
