RRPP brief notes and related configurations

RRPP (Rapid Ring Protection Protocol, fast Ring Network Protection Protocol)
 
Link Layer Protocol dedicated for Ethernet rings. Fast convergence speed. The convergence time is independent of the number of nodes in the ring network.
 
RRPP domain: the same domain ID and control VLAN are connected to each other. Has RRPP main ring, sub-ring, control VLAN, master node, transmission node, Master port and secondary port, public port and edge Port
 
RRPP ring: The main ring level is 0. The child ring level is 1. The health status and fracture status
 
Control VLAN: used to transmit RRPP protocol packets. Only the ports connected to the RRPP ring can be added to the control VLAN. Sub-control VLAN = Master Control vlan id + 1. IP addresses cannot be configured.
 
Data VLAN: used to transmit data packets. The RRPP port can be included or not.
 
Node: master node: one and only one initiator of the active detection mechanism of the ring network status. It is also the decision maker who performs operations after the network topology changes.
Transmission node: monitors the status of the direct RRPP link and notifies the master node of link changes.
Edge node: it is located on both the main ring and the child ring. It is a transmission node on the main ring and an edge node on the child ring.
Secondary edge node: both on the primary ring and the child ring. Used in pairs with edge nodes to detect the integrity of the main ring and prevent Loops
 
Master and slave ports of the master node: The Master port sends detection loop packets. The slave port receives packets and logically blocks data VLANs. Only packets of VLAN control are allowed.
 
The master port and secondary port of the transmission node have no function difference.
 
Public port: the port connecting edge nodes and secondary edge nodes to the main ring
Edge port: the port that only accesses the sub-ring on the edge node and secondary edge node
 
RRPP ring group: a set of child rings configured on Edge nodes or secondary Edge nodes to reduce the number of Edge-hello packets sent and received. The ring group configured on the edge node is the edge node ring group. Only one child ring in the Edge node ring group can send Edge-Hello packets. The ring group configured on the secondary edge node is the secondary edge node ring group.
 
RRPP Message Type
Hello, Fast-Hello, Link-Down, Common-Flush-FDB, Complete-Flush-FDB, Edge-Hello, Fast-Edge-Hello, Major-Fault
 
Timer type
Hello timer, Fail timer, Fast-Hello, Fast-Fail (the transmission node can learn the Hello and Fail timers of the master node through the Hello message, but does not use the Fast-hello message to learn the Fast-hello and Fast-fail timers)
 
RRPP Operating Mechanism
Round Robin mechanism: the master port of the master node periodically sends Hello messages.
Link down Alarm Mechanism: if the link is not found on the master node, it is sent to the master node.
Loop recovery: the port is UP again and not temporarily blocked by the master node (only VLAN control is allowed)
Main link chain down: the Suppression Mechanism of broadcast storms in multiple subordinate sub-rings:
Load Balancing Mechanism: VLAN Load Balancing
Ring Group mechanism: The activation sub-ring with the smallest domain ID and ring ID sends Edge-Hello packets.
Fast Detection Mechanism: uses Fast-Hello and Fast-Edge-Hello packets in milliseconds
 
Typical RRPP networking
Single ring
Tangent ring
Intersection Ring
Dual attribution Ring
Single-ring Load Balancing networking (must be used with MSTP instances)
Intersection ring Load Balancing Network
