Thanks HC,
Two things. I was told this was not a topic for this list. Sorry about =
that.
Since I've already posted, I think I should post what the problem was.
Problem=3DI'm stupid. I wasn't looking in the right place for what I =
was advertising.
I ran:
router#sh ip bgp nei 10.99.200.75 adv
BGP table version is 43, local router ID is 10.1.80.44
Status codes: s suppressed, d damped, h history, * valid, > best, i - =
internal,
r RIB-failure, S Stale
Origin codes: i - IGP, e - EGP, ? - incomplete
Originating default network 0.0.0.0
Network Next Hop Metric LocPrf Weight Path
*> 1.2.3.0/24 1.2.3.3 0 32768 i
router#
I was looking for the network, but not the line that stated:
Originating default network 0.0.0.0
So it was advertising and I've verified it on the remote peers (which I =
should have done first!).
Still doesn't answer why CISCO says you apply default orig to the peer, =
not the peer group (which we've proven is backwards). It shouldn't be =
this way since you may want to use the peer group as a template for =
multiple customers, but they may not all want 0/0 sent to them.
ALSO I didn't need to have 0/0 in my local routing table nor did I need =
to add the BGP command "Synchronization."
According to CISCO (which is actually accurate), it will originate =
default UNCONDITIONALLY, which it does.
I'm still concerned about applying the command to the peer vs. the peer =
group issue.
Sorry about having posted this to Nanog, I'll filter my future questions =
more carefully.
Thanks for everyone who answered!

After you applied default-originate to peer-group, have you done =
soft-clear of your bgp session?
It usually takes a little while for changes in config to propagate, =
unless you force an update using soft clear...
