8. Configure protected VLANs
for the RRPP domain.

By default, no protected VLAN is
configured for an RRPP domain.
Configuring RRPP rings
When configuring an RRPP ring, you must make some configurations on the ports connecting each
node to the RRPP ring before configuring the nodes.
RRPP ports (connecting devices to an RRPP ring) must be Layer 2 Ethernet ports, Layer 2 GE ports, or
Layer 2 aggregate interfaces and cannot be member ports of any aggregation group or smart link
group.
After configuring a Layer 2 aggregate interface as an RRPP port, you can still assign ports to or
remove ports from the aggregation group corresponding to the interface.
Configuring RRPP ports
Perform this configuration on each node's ports intended for accessing RRPP rings.
Follow these guidelines when you configure RRPP ports:
 RRPP ports always allow packets from the control VLANs to pass through.
 For more information about the port link-type trunk, port trunk permit vlan, and undo stp enable
commands, see Layer 2—LAN Switching Command Reference.
 Do not enable OAM remote loopback function on an RRPP port. Otherwise, it might cause
temporary broadcast storms.
 HP recommends using the link-delay command to enable link status rapid report function on an
RRPP port by setting the physical state change suppression interval to 0 seconds, accelerating
topology convergence. For more information about the link-delay command (or the undo
link-delay command), see Interface Command Reference.
