Got it Ed, I think I can understand now. It's more or less a
precaution.
Thanks,

Ben, If you have a copy of Bruce Caslow's book check out Page 462 on
the bottom. He has a nice explanation of the rule of
synchronization.
The way I understand it, synchronization is used when you have BGP
redistributing to the IGP. With Synchronization (on by default) a
router will not announce BGP routes to other EBGP neighbors until the
routes appear in the IGP through the redistribution.
Turning off synchronization will allow the BGP router to advertise
routes to another EBGP neighbor without knowledge of the route in it's
IGP...

My favorite topic...NOT.
I just realized that I don't really know when to use the "no sync"
command in BGP. I mean, why would you want to advertise routes that
you don't have in your route table?
When those routes do get propagated to your route table, won't they
instantly be injected into your BGP because you have advertised them
with the "network XXXX" cmd, eventhough you don't have the "no sync"
cmd?
Please explain...
