Configuring An Rrpp Ring Group; Displaying And Maintaining Rrpp - HP A5830 series Configuration Manual

To do...
• Configure the Hello timer and
Fail timer for the RRPP domain
The Fail timer value must be equal to or greater than three times the Hello timer value.
To avoid temporary loops when the primary ring fails in a dual-homed-ring network, make sure that the
difference between the Fail timer value on the master node of the subring and that on the master node of
the primary ring is greater than twice the Hello timer value of the master node of the subring.

Configuring an RRPP ring group

To reduce Edge-Hello traffic, adopt the RRPP ring group mechanism by assigning subrings with the same
edge node/assistant-edge node to an RRPP ring group. You must configure an RRPP ring group on both
the edge node and the assistant-edge node. You can configure it only on these two types of nodes.
Perform this configuration on both the edge node and the assistant-edge node in an RRPP domain.
To configure an RRPP ring group:
To do...
• Enter system view
• Create an RRPP ring group
and enter RRPP ring group
view
• Assign the specified subrings
to the RRPP ring group
You can assign a subring to only one RRPP ring group. Make sure that the RRPP ring group configured
on the edge node and the RRPP ring group configured on the assistant-edge node contain the same
subrings. Otherwise, the RRPP ring group cannot operate properly.
Make sure that the subrings in an RRPP ring group share the same edge node and assistant-edge node
and that the edge node and the assistant edge node have the same SRPTs.
Make sure that a device plays the same role on the subrings in an RRPP ring group. The role can be the
edge node or the assistant-edge node.
Make sure that the RRPP ring group on the edge node and the RRPP ring group on the assistant-edge
node have the same configurations and activation status.
Make sure that all subrings in an RRPP ring group have the same SRPTs. If the SRPTs of these subrings
are configured or modified differently, the RRPP ring group cannot operate properly.

Displaying and maintaining RRPP

To do...
• Display brief RRPP information
Use the command...
timer hello-timer hello-value fail-
timer fail-value
Use the command...
system-view
rrpp ring-group ring-group-id
domain domain-id ring ring-id-list
Use the command...
display rrpp brief [ | { begin | exclude |
include } regular-expression ]
