Description (partial)

CONNECTED_EP_LEARNING_ERROR is seen for end points that belong to different site in MSO use case.

With MSO, there can be multiple sites naturally and endpoints  that are in different sites can communicate with each other  ( stretched VRF or BD or EPG etc cases).  An endpoint that’s is local in one site ( say Site1)   can be learnt  in COOP database  of  Spines of remote  sites say Site2  ( as per the intended config), but it is  not present in LST of the leafs  of remote site Site2.  This is expected in MSO use case. However, we raise an event  declaring that endpoint is present in COOP but is not local in any of  the leafs since we have not taken the MSO case into account.
