18 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. clear frrp Clear the FRRP statistics counters.
