Junos ® OS 12.3 Ethernet Interfaces Configuration Guide Related Documentation For additional information on configuring Ethernet ring protection switching on MX Series routers, see the Layer 2 Configuration Guide for a complete example of Ethernet rings and information about STP loop avoidance and prevention. • Understanding Ethernet Ring Protection Switching Functionality on page 438 • Configuring Ethernet Ring Protection Switching on page 442 • Example: Ethernet Ring Protection Switching Configuration on MX Routers on page 443 • Example: Configuring Ethernet Ring Protection Switching on EX Series Switches • Junos® OS Ethernet Interfaces Understanding Ethernet Ring Protection Switching Functionality Acronyms 438 • Acronyms on page 438 • Ring Nodes on page 439 • Ring Node States on page 439 • Failure Detection on page 439 • Logical Ring on page 439 • FDB Flush on page 439 • Traffic Blocking and Forwarding on page 440 • RAPS Message Blocking and Forwarding on page 440 • Dedicated Signaling Control Channel on page 441 • RAPS Message Termination on page 441 • Multiple Rings on page 442 • Node ID on page 442 • Bridge Domains with the Ring Port (MX Series Routers Only) on page 442 The following acronyms are used in the discussion about Ethernet ring protection switching: • MA—Maintenance association • MEP—Maintenance association end point • OAM—Connectivity fault management daemon • FDB—MAC forwarding database • STP—Spanning Tree Protocol • RAPS—Ring automatic protection switching • WTR—Wait to restore • RPL—Ring protection link Copyright © 2012, Juniper Networks, Inc.
Ring Nodes Ring Node States Failure Detection Logical Ring FDB Flush Multiple nodes are used to form a ring. For each ring node. There are two different node types: Copyright © 2012, Juniper Networks, Inc. • Normal node—The node has no special role on the ring. • RPL owner node—The node owns the RPL and blocks or unblocks traffic over the RPL. This node also initiates the RAPS message. There are three different states for each node of a specific ring: • init—Not a participant of a specific ring. • idle—No failure on the ring; the node is performing normally. For a normal node, traffic is unblocked on both ring ports. For the RPL owner, traffic is blocked on the ring port that connects to the RPL and unblocked on the other ring port. • protection—A failure occurred on the ring. For normal node, traffic is blocked on the ring port that connects to the failing link and unblocked on working ring ports. For the RPL owner, traffic is unblocked on both ring ports if they connect to non-failure links. There can be only one RPL owner for each ring. The user configuration must guarantee this, because the APS protocol cannot check this. Ethernet ring operation depends on quick and accurate failure detection. The failure condition signal failure (SF) is supported. For SF detection, an Ethernet continuity check MEP must be configured for each ring link. For fast protection switching, a 10-ms transmission period for this MEP group is supported. OAM monitors the MEP group's MA and reports SF or SF clear events to the Ethernet ring control module. For this MEP group, the action profile must be configured to update the interface device IFF_LINKDOWN flag. OAM updates the IFF_LINKDOWN flag to notify the Ethernet ring control module. This feature currently supports only the physical ring, which means that two adjacent nodes of a ring must be physically connected and the ring must operate on the physical interface, not the VLAN. Chapter 32: Configuring Ethernet Ring Protection Switching When ring protection switching occurs, normally an FDB flush should be executed. The Ethernet ring control module (or, on the switch, the ERPS configuration) should use the same mechanism as the STP to trigger the FDB flush. The Ethernet ring control module controls the ring port physical interface's default STP index to execute the FDB flush. 439
