Question about third party VPN remote subnet availability....
My org is a hub-spoke setup....the data center is the hub for the Auto-VPN setup, and all the branch offices are the spokes. We do split tunnel on the Auto VPN, so only those advertised subnets on the Auto VPN go over the S2S VPN, and clients use the local internet connection for everything else.
We are setting up a third party IPSec VPN to an offsite network that is hosting some servers. We are going to peer the Hub MX in the data center to this IPSec tunnel. The clients in the various Spoke networks will need access to the servers being hosted on the remote side of this IPSec tunnel.
Question...how do we advertise the remote network's subnet to the Spoke networks over the Auto VPN, so that clients in the Spoke networks can connect to the servers in the remote network on the other side of the IPSec VPN tunnel? Is that possible with only the Hub MX peering this connection?
