The area 0 network is 172.17.59.16 / 28 with the 3 interfaces in question
being .17 .18 & .19.
The E0 network on R4 is 172.17.59.160 / 30 Ethernet 0 on R4 is set to
172.17.59.161
The token ring network that R2 & R3 share is 172.17.59.128 / 28 with the 2
interfaces set to .129 & .130 and is in OSPF area 1
I have the ip classless statements around the house, I have 'no summary'
statements in the BGP processes, and I am using the appropriate masks in
the BGP network statements.
My OSPF redistribute command includes the subnets parameter.
R2 & R3 can see the 160 network from R4, and R4 can see the 128 and 16
network. R2 & R3 cannot see the .0 network. Since I am subnetting down a
class B, I don't need to worry about the IP subnet zero, but the commands
are there anyway.
I did try a few things last night, including redistributing connected on R1
and the route to the 0 subnet still didn't show up on R2 & R3.
I think that's everything.
Thanks!

Can you supply some IP addressing information on the links? Specifically,
the E0 on router 4, the EBGP link, and the 2 area 0 links on router 1?
