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.
