Navigating VXLAN with vPC: The Critical Roles of VIP and PIP Addresses
In modern data center networks, Virtual Extensible LAN (VXLAN) and Virtual Port Channels (vPC) are foundational technologies, offering enhanced scalability, flexibility, and redundancy. When combined, they create a robust and highly available network infrastructure. However, understanding how IP addresses are handled in a vPC VXLAN environment, particularly the roles of Virtual IP (VIP) and Primary IP (PIP) addresses, is crucial for ensuring optimal traffic flow and preventing common pitfalls like black-holing. ...
