PPPoe link down - no route recreated

Hi,

We have two WAN connections with the latest stable version of firmware (7.23.2).

WAN connection via PPOE, has a distance with 1, and route automatically created.

WAN 2 connection via DHCP client, has a distance of 2, with route automatically created.

Today I found that my PPPOE connection dropped for a few hours and came back. WAN #2 took over the routing as normal. However, when the PPPOE came back up the router failed to create a route with a distance of 1 again. Only when I disabled and re-enabled the PPPOE interface; did the route distance of 1 get recreated.

This feels like a bug to me?

Thoughts anyone?
