PPPoE for 1Gbps clients

Fri Nov 08, 2019 2:25 pm

Hi Guru,

I tried to configure PPPoE server to provide 1Gbps to our client. However, speedtest for 1 connected client only shows 500Mbps-600Mbps if clent connect via PPPoE. If client connect directly without PPPoE via static IP, we can achieve 900+Mbps. Our upstream is 10Gbps.

We are using CCR1009 with CPU load is less than 5% on each core.

Please help.

Try to change your mtu values.
For this type of clients personally I don't connect them via pppoe but with static ip address given via my radius server to limit each one of them and for expiration purposes.

Your throughput may be impacted by out of order packets due to fragmentation. If you have at least 1508 layer 2 MTU between your clients and the server, you can change MTU and MRU to 1500 on both sides. Then PPPoE should not theoretically be any more overhead than simply adding a VLAN tag and I would expect you to be able to get full 1Gbps.
