1.2 RRPP Configuration Task List
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
Caution:
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 should not 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.
The ports accessing an RRPP ring must conform to the following conditions:
z Trunk port;
z Layer 2 Ethernet port or layer 2 GE port;
z Except for aggregation port and loopback port;
z Port with STP, 802.1x, MAC address authentication, voice VLAN disabled;
z Do not enable OAM remote loopback function on an RRPP port. Otherwise, this
may cause temporary broadcast storm;
z Enable link status rapid report function on a port accessing an RRPP ring (the
link-delay of the port is set to 0) to accelerate topology convergence.
