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...
