How to test

Configure the secondary node API port (not default)

set service https api keys id KID key 'foo'
set service https port '8443'

On the primary node, use this port to connect to the secondary API for config-sync:

set service config-sync mode 'load'
set service config-sync secondary address '192.168.122.11'
set service config-sync secondary key 'foo'
set service config-sync secondary port '8443'
set service config-sync section protocols ospf

Change anything under protocol ospf on the primary node

vyos@r4# set protocols ospf area 0 network '192.0.2.0/30'
[edit]
vyos@r4# commit
INFO:vyos_config_sync:Config synchronization: Mode=load, Secondary=192.168.122.11
[edit]
vyos@r4# 

Check on the secondary node protocol ospf

vyos@r1-right# show protocols ospf 
 area 0 {
     network 192.0.2.0/30
 }
