non500-isakmp to 2 hub routers?

I have a hub and spoke design where the spokes do IPSec tunnels to 2 different hub sites for redundancy and as a backup link. These spokes are behind a nat router provided by an ISP. Do I need to configure a different port other than 4500 for the second IPSec tunnel?

You dont need IPsec use SPI (Security parameter index) for identification peers

This makes no sense - can you explain with more detail?
