Force10 Resilient Ring Protocol (FRRP)
Force10 resilient ring protocol (FRRP) is supported on Dell Networking S4820T platform.
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.
