Force10 OS Resilient Ring Protocol
(FRRP)
Force10 OS resilient ring protocol (FRRP) is a proprietary protocol for that offers fast convergence in a
Layer 2 network without having to run the spanning tree protocol (STP).
The resilient ring protocol is an efficient protocol that transmits a high-speed token across a ring to verify
the link status. All the intelligence is contained in the master node with practically no intelligence required
of the transit mode.
Important Points to Remember
• FRRP is media- and speed-independent.
• FRRP is a Dell Networking proprietary protocol that does not interoperate with any other vendor.
• Spanning Tree must be disabled on both primary and secondary interfaces before Resilient Ring
protocol is enabled.
• A VLAN configured as the control VLAN for a ring cannot be configured as a control or member VLAN
for any other ring.
• Member VLANs across multiple rings are not supported in Master nodes.
• If multiple rings share one or more member VLANs, they cannot share any links between them.
• Each ring can have only one Master node; all others are Transit nodes.
• FRRP is not supported on port extender (PE) ports.
