I’m activating a new PPPoE server, a CCR1009, and for the first time i saw this message, when pppoe clients where connecting:
18:51:16 pppoe,info PPPoE connection established from EC:08:6B:XX:XX:XX
18:51:16 pppoe,info PPPoE connection established from EC:08:6B:XX:XX:XX
18:51:16 pppoe,ppp,info,account xxx-yyy logged in, 146.247.ab.cd
18:51:16 pppoe,ppp,info <pppoe-xxx-yyy>: authenticated
18:51:16 pppoe,ppp,info <pppoe-xxx-yyy>: connected
18:51:17 pppoe,ppp,info <pppoe-xxx-yyy>: terminating... - spurios reauthentication
18:51:17 pppoe,ppp,info,account xxx-yyy logged out, 0 54 72 3 5
18:51:17 pppoe,ppp,info <pppoe-xxx-yyy>: disconnected
This happen only with two clients, the other 60 reconnected without problems
The setup is:
- the CCR has two interfaces, ether5 and ether6, bonded toghether with LACP;
- on bond1 there are 3 VLAN: wan (internet), lan (server), ptp (wireless link to the network);
- from the CCR to the RB750, where there are 4 sectors, there are 4 VPLS tunnels, one for each sector;
- pppoe connections are encapsulated in VLAN, ID 10, but, for legacy configuration, there is also pppoe servers on “native” interfaces, the VPLSs
- VPLS interfaces are unique port for bridges (workaround to avoid mass disconnection from VPLS disconnection)
So, a default configuration is something like this
/ interface vpls
add name=vpls1 ...
/ interface bridge
add name=vpls1-bridge
/ interface bridge port
add bridge=vpls1-bridge interface=vpls1
/ interface vlan
add name=vlan_pppoe-vpls1 interface=vpls1-bridge
/ interface pppoe-server server
add interface=vlan_pppoe-vpls1
add interface=vpls1-bridge
My workaround was to disable pppoe server on native interfaces, because I noticed
18:51:16 pppoe,info PPPoE connection established from EC:08:6B:XX:XX:XX
18:51:16 pppoe,info PPPoE connection established from EC:08:6B:XX:XX:XX
and enabling pppoe debug I saw PADI e PADO packet both from native and VLAN interfaces.
Tomorrow I’ll downgrade the CCR (but then I’ll have to disable bonding interface).
Any idea?
