RRPP protocol causing network loops

Dear All,

I am working in the Train metro domain and configured a 5510 HP switch with RRPP protocol for 25 locations/metro stations, but each location has 2 switches stacking (Totally 50 switches).

Stacking configuration:

irf domain 100

 irf mac-address persistent always

 irf auto-update enable

 undo irf link-delay

 irf member 1 priority 32

 irf member 2 priority 1

 

irf-port 1/1

 port group interface FortyGigE1/1/1

#

irf-port 1/2

 port group interface FortyGigE1/1/2

#

irf-port 2/1

 port group interface FortyGigE2/1/1

#

irf-port 2/2

 port group interface FortyGigE2/1/2

 

Between each stations configured LACP using two links (10G+10G) :

interface Bridge-Aggregation10

 description RING-PORTS Link Aggregation

 port link-type trunk

 undo port trunk permit vlan 1

 port trunk permit vlan 19 69 100 192 194 196 to 197 200 999 2140 to 2143 2145 to 2147

 port trunk permit vlan 2200 to 2201 2211 to 2215

 link-aggregation mode dynamic

 undo stp enable

 

RRPP configuration: (Master also configured in one of the location and RRPP status is showing properly)

 rrpp domain 1

 control-vlan 20

 protected-vlan reference-instance 1

 fast-detection enable

 fast-timer hello-timer 10 fail-timer 30

 ring 1 node-mode transit primary-port Bridge-Aggregation10 secondary-port Bridge-Aggregation20 level 0 

 ring 1 enable 

Issue: Facing looping issues the entire line if the RRPP ring is closed, if i broke the ring , it will work properly. Could you please give me some suggestion, how to solve this issue?

Re: RRPP protocol causing network loops

Hi @MadhuAlstom 

Have you created  MST instance and region-configuration for the VLAN passing between the switches ?

stp region-configuration
instance 2 vlan 1<>
active region-configuration

I suggest you to refer below setps if in case you have missed something.
