ExpressRoute/BGP issue on Dell S4048T-ON
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.
