Force10 Resilient Ring Protocol (FRRP)
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.
