MEDIA ACCESS CONTROL ADDRESS LEARNING LIMIT ON A VIRTUAL EXTENSIBLE LOCAL AREA MULTI-HOMED NETWORK ETHERNET VIRTUAL PRIVATE NETWORK ACCESS PORT

摘要

Systems and methods for enforcing media access control (MAC) learning limits (MLLs) on multi-homed access ports comprise configuring MLL violation actions to be performed by a virtual extensible local area network (VxLAN) tunnel endpoint (VTEP). The VTEP is multi-homed to VTEPs and comprises an Ethernet segment (ES) access port. A BGP EVPN or similar protocol may be used to communicate MLL information across VTEPs participating in the multi-homed ES to keep MACs and MLL violation actions consistent. The violation actions may comprise initiating a shutdown message to shut down an ES. Once an MLL violation associated with a MAC that has been received at the VTEP is detected, the VTEP may enforce the MLL by performing one or more of the configured MLL violation actions and propagate the same to other VTEPs.
