Force10 Resilient Ring Protocol (FRRP)

Overview

Force10 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. 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.

The symbols

s z under command headings indicate which Dell Networking — , S-Series

or Z-Series, respectively — support the command.

Commands

The FRRP commands are:

• clear frrp

• debug frrp

• description

• disable

• interface

• member-vlan

• mode

• protocol frrp

• show frrp

• timer

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 control VLAN for a ring cannot be configured as 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.
