Nice research :) I didn't bother to stretch back pre 93'ish :)

I don't disagree with most of your points, but really think synch should be
disabled in all cases at all times along with auto summary. It should be
disabled by default and indeed shouldn't even be included as a configurable
option.

I understand the what sync does and I also assume that someone setting
up such an config, dual homed full routing, should understand BGP
fundamentals.
It's like auto summerization, I have never seen it fix anything but I
have seen it cause problems many times.

It's not default for the same reason why unicast rpf (antispoofing) is
not default in ISO; because people are stupid, and under poor design, it
could produce very undesirable and hard to troubleshoot results. In
other words, if you don't know why you are disabling synchronization,
don't do it.

I can think one one good reason why you would disable sync, you can't
redistribute 100K routes into ANY IGP. Why are you so concerned about
disabling sync?? It should be default.

BGP Rules of thumb:
BGP advertised prefix must also exist in local IGP table.
iBGP learned prefix must also exist in local IGP table
-or use #no sync on iBGP learning router, but if you do, you'd sure as
hell better know why you disabled it.

Thanks Peter,
I just got the following link which confirms what you
say.
http://www.cisco.com/warp/public/459/bgp_noad.html#intro
The BGP table must have got populated since the
networks where directly connected.
I also had auto-summary on (Dohh), using /30 s (Dohh,
Dohh).

Network statements only advertise routes that exists in the routing
table. Further, if you use a "mask" on the statement, you need to match
the prefix exactly. Usually, one uses static routes to null0 to pin up
aggregate routes, or normal static routes (non null0) for others.

did you turn off sync.?

Hi Group,
Hope someone can help out with this as I don4t have
access to my kit at the moment.
I tried to set up my first BGP lab last week.
I configured a full iBGP mesh, three routers connected
in a triangle via serial lines.
I set up (neighbour( statements on each router (Hope
