/24 multihoming issue

Thu Oct 20 06:17:09 UTC 2005

I opened ticket with both 701 and 19094 when we did
failover 2 weeks ago. Both 701 and 19094 insist that
they just take the route and send it out to the rest
of the world. And at that time, I thought it was RADB
problem and agreed to close the tix.
Now that RADB is fixed, I'm back at square one with
more confusions :(
I will open case with both 701 and 19094 soon. I am
making sure that I'm not missing a smoking gun.
