Hello;
I have the following network topology and when there is any change in the network I lose connectivity with the switches for a long time. also when I configure the neighbor port on port 52 of switch 3 I permanently lose connectivity between some switches.

these are my settings:

Router1:

create vlan "ERPS_RING_1"
configure vlan ERPS_RING_1 tag 301
create vlan "GESTION"
configure vlan GESTION tag 1000
enable sharing 29 grouping 29,33 algorithm address-based L2 lacp

configure vlan ERPS_RING_1 add ports 1,29 tagged
configure vlan GESTION add ports 1-32,34-36 untagged
configure vlan GESTION ipaddress 10.1.0.251 255.255.0.0
enable erps
create erps ERPS_RING_1
configure erps ERPS_RING_1 add control vlan ERPS_RING_1
configure erps ERPS_RING_1 ring-port east 29
configure erps ERPS_RING_1 ring-port west 1
enable erps ERPS_RING_1
configure erps ERPS_RING_1 add protected vlan GESTION

R2:

Hi cpacho,

Did you double checked that spanning tree is disabled on the ERPS ring-ports?

Hello,
if I have checked that there is no STP in any of the ports that form the ERPS
#
# Module stp configuration.
#
Regarding the GESTION vlan, it is the vlan that I need to send the untagged traffic in the trunk links.
