Given you only want the /32 you can't use the address (with netmask) directly from the interface. You could do this with bgpd by *not* announcing it directly from bgpd.conf but instead run something that monitors the DHCP address, and uses "bgpctl network flush" and "bgpctl network add $ip/32". Or you could monitor the DHCP address and add that same address but with a /32 netmask to a new loopback interface (e.g. lo1) and redistribute that loopback address. Either way, to monitor the dhcp address you can watch /var/db/dhclient.leases.$iface, you can try entr (in packages) to trigger on updates rather than polling. > Is this such an exotic set-up? Yes.
