Dell S4048T User Manual

FRRP groups. Switch R3 has two instances of FRRP running on it: one for each ring. The example topology
that follows shows R3 assuming the role of a Transit node for both FRRP 101 and FRRP 202.

Important FRRP Points
FRRP provides a convergence time that can generally range between 150ms and 1500ms for Layer 2
networks.
The Master node originates a high-speed frame that circulates around the ring. This frame, appropriately, sets
up or breaks down the ring.
• The Master node transmits ring status check frames at specified intervals.
• You can run multiple physical rings on the same switch.
