Ok, I found out what I was doing wrong, I had to have a network statement in
there that fell into the range I was trying to aggregate. Too bad I
couldn't find this an hour and a half ago, but hey, now I will never
forget!!!
router bgp 200
network 172.10.55.0 mask 255.255.255.0
aggregate-address 172.10.0.0 255.255.0.0 summary-only
neighbor 172.10.6.1 remote-as 200
neighbor 172.10.6.1 next-hop-self
neighbor 192.19.15.1 remote-as 100
neighbor 192.19.15.1 soft-reconfiguration inbound

Subject: BGP Aggregate Address
I have an aggregate address configured under bgp, and as far as I know,
as long as there is a route that falls into that range in the routing
table I should be announcing that aggregate to my neighbors. Here is
the config of the bgp on the router, and its routing tables. I can't
get this router to advertise the aggregate to 192.19.15.1 or 172.10.6.1,
am I doing something wrong here? If I redistribute static and put a
static route in there I have no problem. There are no filters applied
anywhere.:
