Important Frrp Points - Dell S6100 Configuration Manual

In the following example, FRRP 101 is a ring with its own Control VLAN, and FRRP 202 has its own Control VLAN running on another ring.
A Member VLAN that spans both rings is added as a Member VLAN to both 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.
• One Master node per ring — all other nodes are Transit.
• Each node has two member interfaces — primary and secondary.
• There is no limit to the number of nodes on a ring.
• Master node ring port states — blocking, pre-forwarding, forwarding, and disabled.
• Transit node ring port states — blocking, pre-forwarding, forwarding, and disabled.
