Hi someone has build a BRAS with HA on vyos ?
Can you share an exemple of config please or a scheme
Thank you
Hello @Mohamed_El_Bouddunti, many people usually deploy 2 or more BRAS on L2 network (for PPPoE BRAS) and PPPoE Clients connect to the BRAS which first replies.
https://docs.vyos.io/en/latest/configuration/service/pppoe-server.html
And for user synchronization we just need to use the same radius server between the two bras ? And If the first bras down the client will be connect automatically to the second with the same pppoe credentials it’s correct ?
Yes, all correct. You need to use the same RADIUS server/servers for both BRAS.
VyOS also supports advanced balancing feature based on pado-delay.
set service pppoe-server pado-delay <delay> sessions <bumber>
But the problem I can just use I public IP.
I connected behind and ISP for PPP service with a /30 he forwarding to my bras all request finishing “@MYCOMPANY” in this case I can only reply with 1 bras
Do you have an solution ?
I think in this case you need to use clustering
vyos@vyos# set cluster
Possible completions:
dead-interval
Interval after which a node is considered dead after missing heartbeats (milliseconds)
+> group Name of resource group for clustering [REQUIRED]
+ interface Interface(s) for sending/receiving heartbeat packets [REQUIRED]
keepalive-interval
Time interval between heartbeat packets (milliseconds)
mcast-group Multicast group for sending/receiving heartbeat packets
monitor-dead-interval
Interval after which a monitor node is considered dead (milliseconds)
pre-shared-secret
Pre-shared secret for authentication between cluster nodes [REQUIRED]
Or VRRP with transitional scripts and enabling pppoe server on some interface.
Tell me if you need additional explanation.
