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
