How to configure exchange hub transport with exchange servers

We currently have exchange 2007 and Exchange 2010 servers and Smart SMTP host box as an email filter.
Hub Transport on 2007       has few connectors configured. Here is a list of connectors on both servers
Column1      Column2      Column3
server      network      network
      Use this local IP      receive from remote servers
07 local      second local domain      local subnets to relay
07 clients      all on port 587      0.0.0.0 - 255.255.255.255
07 default      Smart Host IP      Smart Host IP
07 to 2010      All IPV4      Exchange 2010 IP
            
      All IPv6 587      ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff
2010 client      all IPv4 587      0.0.0.0 - 255.255.255.255
            
Default      All IPV6 25      ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff
      All IPV4 25      0.0.0.0 - 255.255.255.255


How should I reconfigure 2010 to have transport redundancy so that email will flow even when ex 2007 is down as well as flow between servers? I understand that I have to change 2010 default to point both to smart host so I am not looking for simple guesses rather and advice from an expert on correct configuration so I can avoid trial and error method on my production servers

"07 to 2010      All IPV4      Exchange 2010 IP"

If that is what I think it is, then it is unnecessary if both Exchange servers are in the same Exchange org (ie can see each other). It should be removed. Exchange doesn't need a connector to link them.

For outbound email, just have a Send Connector on both versions that points to the smart host.
For inbound email, have your smart host configured to send email to both hosts. Exchange will sort out routing.
If you have email delivered directly (so MX records point to the Exchange server), then have each side on their own external IP address and both listed in the MX records.

Keep it very simple, and leave the routing of email to Exchange.

my MX points to the Smart host
Smart host points to both servers
so do you suggest to
1.  remove 07to 2010
2. set default connector on 2010 both "Use this local IP" and  "Recieve email from Remote servers that have These IP" to my SMART SMTP host IP address under IPV4?
3. what about IPV6 on both?

IPv6 you can leave alone.

If you are going to change the default receive connector, then ensure that you have your internal subnet listed as well as the smart host. Exchange transfers email between servers using SMTP, so the restriction has to allow them to connect.

could you be more specific.
Smart host is on my local net
what should I have for IPV$ on "Use this local IP" and  "Recieve email from Remote servers that have These IP"  ?

You need to ensure that under the Receive Email from remote servers, that you have all IPs that could send email to that server listed. That will be your smart host and other Exchange servers. Don't touch the binding information in the top box.
