some pointers here.  I am currently having trouble with exactly such
a combination which has led me down the road of trying to find where
an mroute for a host I turned off three weeks ago is getting refreshed
from (it shows as proxy joined on one router (flags CLX) and CLT, registering
on the local router....

Good luck!
