I have been having problems with the bri interface being brought up for reasons i can't work out. I noticed that if i ping an ip address the bri interface stays down but if i traceroute to the same ip then the bri interface comes up:
Dial String Successes Failures Last DNIS Last status

If i do a show ip route for the destination ip it shows the serial interface as i would expect:
sh ip route 10.2.44.200

why does the router send a broadcast via the bri interface when i traceroute?
debug dialer packet shows following:

Any further data needed then please let me know.
