What is Resilient Ethernet Protocol?

What is Resilient Ethernet Protocol?

The Resilient Ethernet Protocol (REP) is a Cisco proprietary protocol that provides an alternative to the Spanning Tree Protocol (STP). REP provides a way to control network loops, handle link failures, and improve convergence time.

How does Cisco rep work?

REP Ports

1. A port configured as a regular segment port starts as a failed port.
2. After neighbor adjacencies are determined, the port transitions to the alternate port state, blocking all VLANs on the interface.
3. When a failure occurs in a link, all ports move to the failed state.

How do I setup a Cisco rep?

To configure REP segments, you configure the REP administrative VLAN (or use the default VLAN 1) and then add the ports to the segment using interface configuration mode. You should configure two edge ports in the segment, with one of them the primary edge port and the other by default the secondary edge port.

What is Rep topology?

REP is a protocol used in order to replace the Spanning Tree Protocol (STP) in some specific Layer 2 network designs. The most current STP specification is Multiple Spanning Trees (MST), defined in 802.1Q-2005.

What is a rep ring?

REP is a distributed and secure control plane protocol that does not rely on a master switch controlling the status of the ring. By default, REP automatically elects an alternate port (the switch port being blocked). Any REP port within the REP topology can initiate a switchover to unblock the alternate port.

What is Rep Admin VLAN?

rep admin vlan. To configure a Resilient Ethernet Protocol (REP) administrative VLAN for REP to transmit hardware flood layer (HFL) messages, use the rep admin vlan command in global configuration mode. To return to the default configuration with VLAN 1 as the administrative VLAN, use the no form of this command.

What is Flex Links Cisco?

Flex Links are a pair of a Layer 2 interfaces (ports or port channels), where one interface is configured to act as a backup to the other. Flex Links provide link-level redundancy that is an alternative to Spanning Tree Protocol (STP). STP is automatically disabled on Flex Links interfaces.

What is flex in networking?

Flex links is a network switch feature in Cisco equipment which enables redundancy and load balancing at the layer 2 level. The feature serves as an alternative to Spanning Tree Protocol or link aggregation.

What is EtherChannel Cisco?

EtherChannel is a port link aggregation technology or port-channel architecture used primarily on Cisco switches. It allows grouping of several physical Ethernet links to create one logical Ethernet link for the purpose of providing fault-tolerance and high-speed links between switches, routers and servers.

What does the resilient Ethernet protocol ( REP ) do?

Resilient Ethernet Protocol (REP) The Resilient Ethernet Protocol (REP) is a Cisco proprietary protocol that provides an alternative to the Spanning Tree Protocol (STP). REP provides a way to control network loops, handle link failures, and improve convergence time.

What are the limitations of Cisco resilient Ethernet protocol?

Here are some of the limitations of REP: No plug-and-play No protection against misconfiguration (easy to create loops) Limited amount of redundancy (only able to withstand one link failure) Cannot discover global topology (only segment topology) Cisco proprietary

What’s the difference between Cisco spanning tree and Rep?

The Resilient Ethernet Protocol (REP) is a Cisco proprietary protocol that provides an alternative to the Spanning Tree Protocol (STP). REP provides a way to control network loops, handle link failures, and improve convergence time.

What is the name of the Cisco Ethernet protocol?

Resilient Ethernet Protocol (REP) The Resilient Ethernet Protocol (REP) is a Cisco proprietary protocol that provides an alternative to the Spanning Tree Protocol (STP).
