Description

I have an issue getting G.8032 failover to function properly

Symptoms

Topology:

 

 

 

 

 

Topology configured as ring using ERPS, when the link between R5 and R1 is disabled, traffic from R2 to R4 does not get diverted to the RPL device "R3", any other link disabled works fine and R3 opens its port

Solution

The failover issue can be resolved by switching from the ge-0/0/0 interface to the irb interface. This change allows Layer 3 traffic to be properly integrated into the ring network.

 

// Solution //

 

Below config needs to be added:

Add:

 

set interfaces irb unit 0 family inet address <IP_address from ge-0/0/x>

set bridge-domains CUSTOMER routing-interface irb.0

 

Remove:

set interfaces ge-0/0/0 unit 0 family inet address <IP_address from ge-0/0/x>

The above configs ensure that L3 traffic is routed via the IRB interface, allowing proper communication.

 

R2:

 

set interfaces irb unit 0 description CPE

set interfaces irb unit 0 family inet address 192.168.1.2/30

 

set bridge-domains CUSTOMER vlan-id none

set bridge-domains CUSTOMER interface xe-0/3/0.300

set bridge-domains CUSTOMER interface xe-0/3/1.300

set bridge-domains CUSTOMER routing-interface irb.0

set bridge-domains G.8032_CONTROL interface xe-0/3/0.3

set bridge-domains G.8032_CONTROL interface xe-0/3/1.3

 

R4:

set interfaces irb unit 0 description CPE

set interfaces irb unit 0 family inet address 192.168.1.1/30

 

set bridge-domains CUSTOMER vlan-id none

set bridge-domains CUSTOMER interface xe-0/3/0.300

set bridge-domains CUSTOMER interface xe-0/3/1.300

set bridge-domains CUSTOMER routing-interface irb.0

set bridge-domains G.8032_CONTROL interface xe-0/3/0.3

set bridge-domains G.8032_CONTROL interface xe-0/3/1.3
