if you are allowed to also trade transit across the IX then you have to
do nothing. Just ask them to give you the full table and let them tag
their own prefixes so that you are able to distinguish between peering
and transit.

if you are _not_ allowed to trade transit across the IX then you need an
additional interface anyway to get the backup transit. Establish an
additional BGP session across this interface and prefer routes via peering.
