Hi All,
I have 2 PPPoE servers on the same vlan. PPPoE server 1 is erx1410, MAC = Unispher_40:08:a1 ,PPPoE Server 2 is erx1440,mac = Unispher_41:eb:42 .
See the PPPoE log below,I am wondering why the ERX1440 send the PADR to PCs and not ERX1410? Does the Junose support "delayNumber of seconds that the PPPoE underlying interface waits after receiving a PADI packet from the client before sending a PADO packet in response."?
Anybody know how to implement 2 PPPoE servers? one as primary, one as backup?

delayNumber of seconds that the PPPoE underlying interface waits after receiving a PADI packet from the client before sending a PADO packet in response. In networks with mesh topologies, you might want to designate a primary PPPoE server and a backup PPPoE server for handling a particular service request. In such a scenario, you can configure a delay for the associated service name tag on the backup PPPoE server to allow sufficient time for the primary PPPoE server to respond to the client with a PADO packet. If the primary server does not send the PADO packet within the delay period configured on the backup server, then the backup server sends the PADO packet after the delay period expires.
