config vpn ipsec phase1-interface
edit "Hub_to_Spokes"
set type dynamic <-- Must be a dial-up server, not static
set mode-cfg enable <-- RECOMMENDED: Dynamically hands out IPs to spokes
set ipv4-start-ip 169.254.1.1
set ipv4-end-ip 169.254.1.254
set net-device disable <-- Disabled on Hub to share a single interface for all dials
next
end

Using loopback interfaces for BGP, meaning tunnel interfaces dont need IP addressing, thus mode-cfg is unnecessary
