ExpressRoute/BGP issue on Dell S4048T-ON

Hello all:

I've got an AT&T ADX/ExpressRoute connected and the routes coming in through eBGP show up correctly. However, when I advertise my local network, we lose all connectivity to Azure. 

Here is the show ip bgp ipv4 unicast:

    Network            Next Hop            Metric     LocPrf Weight Path
*>  10.0.0.0/16        10.220.56.2                            50000 13979 12076 i
*>  10.1.0.0/16        10.220.56.2                            50000 13979 12076 i
*>  10.2.0.0/16        10.220.56.2                            50000 13979 12076 i
*>  10.220.56.0/30     10.220.56.2                            50000 13979 i
*>  10.220.56.8/30     10.220.56.2                            50000 13979 i
*>  10.220.56.12/30    10.220.56.2                            50000 13979 i

When I edit the BGP config to advertise my local network it shows up like this:

n*> 192.168.1.0/24 0.0.0.0                                        32768 i

Which is the wrong path. Instead the next-hop should be 10.220.56.2. 

I've noticed that when I try add network using address-family configuration, I'm not able to input ipv4 unicast on the advertisement. The router only seems to allow address-family ipv4 multicast or address-family ipv6 unicast, which does me no good since we are talking ipv4 here. Any guidance on how to get to the right configuration would be appreciated greatly, as I believe this is the only thing holding up connectivity on our ExpressRoute currently.
