Is there a possibility to bring a Dialer interface down?
Or at least remove the route x.x.x.x via Dialer1
problem is that dialer interface remains up/up
I have workarounds but the best way is to remove the route when the Dialer interface has no ip route
I thought to do something with track??
Track 1
Interface Dialer1 ip routing
IP routing is Down (no ip addr)
1 change, last change 00:07:32
Can I do something with this?

Hello Rik,
dialer interfaces are spoofed up that is they are supposed to be up/up to allow for the DDR to take place.
you should using floating static routes like
ip route 10.0.0.0 255.0.0.0 dialer1 220
in order to use dialer interface only as a backup route
Hope to help

dialer interface is of an ADSL link (primary link). A static route TOHUB via dialer1 is used to initiate a tunnel. When ADSL goes down, the backup route must setup a route towards HUB. You see the blackholing...
There are workarounds: another HuB_IP for backup,..., create a static route with a lower AD (as backup interface is down by default it won't be installed but here is a risk that the primary won't take over unless after idle time-out)
but the situation as explained is simplified but represents the problem as it's explained.
Nothing possible with tracking interface (track ip routing) and remove a route from the routing table ?
