there are not multipaths, here is my very simple testsetup:
all network are /24 and starting with '10.', all MAC-addrs=00:00:IP
HOST
---------lsr1-------------lsr3----------------lsr6---------next LSR not
started
0.30.2 1.2.1 1.2.3 3.6.3 3.6.6 10.6.6

really 'trace all', is there no quieter option ?
i start for today with the kernel log: (tomorrow i'm going to send the
'strace all' dump from lsr1, lsr3 and lsr6)
