ACI Fabric start learning external remote IP’s locally on the Leaf switches . Due to this reason, traffic is locally dropped on Leaf Sw03 instead of going outside the fabric. This issue basically interrupted most of the External & Internal services because (ACI firewall IP’s and External LB IP’s plus additional IP’s from HQ and Branch Network) are learning on the Leaf switch03 & 04 Endpoint table.

 

Please find below the EndPoint table as under:

 

LFSW03# show endpoint ip 10.x.x.1xx

Legend:

s - arp              O - peer-attached    a - local-aged       S - static         

 V - vpc-attached     p - peer-aged        M - span             L - local          

 B - bounce           H - vtep
