Hello,
We have several Mikrotiks, all with version 7.12.1 or higher and different hardware tile, arm, etc. It happens that unexpectedly, the PPPoE server kills all client connections. The clients reconnect and everything seems to work. These disconnections occur more or less frequently. It doesn't follow any specific pattern.

.....
and so on.
After restarting pppoe sessions, the /32 routes associated with some clients with a specific Address List are not advertised by ospf correctly. This is also absolutely random. This OSPF instance have a out filter like : if ( dst in ROUTE32) { accept }, where ROUTE32 is a Adress List.
PPPoE server Configuration:
/interface pppoe-server server
add authentication=pap,chap default-profile=FTTH disabled=no interface=VLAN keepalive-timeout=20 max-mru=1492 max-mtu=1492 service-name="PPPoE FTTH"
/ppp profile
set *0 dns-server=8.8.8.8 local-address=X.X.X.X only-one=yes
add change-tcp-mss=yes dns-server=8.8.8.8 interface-list=PPPoE_FTTH local-address=X.X.X.X name=FTTH only-one=yes use-encryption=no
OSPF Configuration:
/routing ospf instance
add disabled=no name=default-v2 originate-default=never out-filter-chain=ospf-out redistribute=connected,static router-id=X.X.X.X
/routing ospf area
add disabled=yes instance=default-v2 name=backbone-v2
add area-id=1.1.1.1 disabled=no instance=default-v2 name=wifi_network-v2
/routing ospf interface-template
add area=wifi_network-v2 auth-id=1 auth-key="" cost=10 disabled=no interfaces=sfp-sfpplus1 networks=172.16.62.48/30 priority=1 use-bfd=yes
add area=wifi_network-v2 disabled=no interfaces=lo networks=10.127.248.210/32 passive priority=1
add area=wifi_network-v2 disabled=no networks=10.8.1.0/24,10.8.32.0/21,10.8.40.0/21 passive
We don't know what could be happening. I think configurations seems correctly.
Thanks
