G’day g’day.
We use Routerboards primarily for MLPPP-PPPoE deployments.
We’ve noticed over the years that intermittently, some Routerboards will establish more PPPoE sessions than they have links to DSL modems.
i.e. if we’re using ports 1 through 4 as our uplinks to DSL modems (in bridged mode), we’ll sometimes see 5 or more active PPPoE sessions on the Routerboard itself. This results in service degradation.
Is there any parameter that can be set to limit the total # of PPPoE sessions being made from the device? So if we have 4 DSL modems connected to the Routerboard, we can limit it to 4 active PPPoE sessions?
We’ve already got scripts in place to detect when excessive PPPoE sessions exist and to try to correct it via disabling and re-enabling the MLPPP PPPoE interface, but ideally, we’d like a way to prevent the issue from happening in the first place.
I’ve poked around online and in message forums, but I haven’t come across anything that would limit the # of PPPoE sessions as desired, so I suspect this function doesn’t exist, but I figured I’d ask anyway!
Thanks!
