Colorless ports allow network devices to move or replace endpoints without changing port-level configurations, typically by automatically assigning network policies dynamically to any port.
HPE Aruba’s solution for colorless ports is the VNBT (Virtual Network Boundary Tagging) feature. VNBT allows dynamic segmentation of traffic, so ports can automatically take on the policies assigned to devices regardless of physical port location.
VRRP is a first-hop redundancy protocol and unrelated to port colorlessness.
VSF (Virtual Switching Framework) is for switch stacking.
VRF (Virtual Routing and Forwarding) is for traffic segmentation.
Thus, VNBT is the correct feature to meet colorless port requirements.
