RFC 3619 Extreme Networks' Ethernet Automatic Protection Switching (EAPS) Version 1 is related to
RRPP.
RRPP Configuration Task List
z
RRPP does not have an auto election mechanism, so you must configure each node in the ring
network properly for RRPP to monitor and protect the ring network.
z
Before configuring RRPP, you need to construct a ring-shaped Ethernet topology physically.
You can create RRPP domains based on service planning, specify control VLANs and data VLANs for
each RRPP domain, and then determine the ring roles and node roles based on the traffic paths in each
RRPP domain. You can configure devices through the following configurations.
Complete the following tasks to configure RRPP:
Task
Description
Configuring Master Node
Required
Configuring Transit Node
Optional
Configuring Edge Node
Optional
Configuring Assistant Edge Node
Optional
Configuring Ring Group
Optional
To reduce Edge-Hello traffic, you can adopt the ring group
mechanism, that is, assign subrings with the same edge
node/assistant-edge node to a ring group.
z
It is recommended to configure the primary ring first and then the subring when you configure an
RRPP domain. Moreover, a Ring ID cannot be applied to more than one RRPP ring in one RRPP
domain.
z
If a device lies on multiple RRPP rings in an RRPP domain, only one primary ring exists. The
device serves as either an edge node or an assistant-edge node on the subrings.
z
The total number of rings configured on a device in all RRPP domains cannot be greater than 16.
z
Modification of node mode, port role and ring level of an RRPP ring is prohibited after configuration.
If needed, you must first delete the existing configuration.
z
During load balancing configuration, different protected VLANs must be configured for different
domains.
Ports connected to an RRPP ring must meet the following conditions:
