[j-nsp] ERX310 disconnects and radius wrong source address

[Tom T]

Hello,

We are using an ERX310 for DSL aggregation (PPPoE)

A day ago we had a strange problem.
All PPPoE session were disconnected and then they tried to reconnect,
normally this shoudn't be a problem.
But the users could not authenticate because de ERX used an IP-address from
one of the loopback interfaces as source address. So the RADIUS-server
denied requests.

Eventually i deleted the loopback interfaces the radius config and added the
radius config and the loopback interfaces again and then all connection came
up.

Does anyone has an idea what the disconnects could have been caused and why
the ERX used a different source address ?

Kind reagards,
Tom
