If you are trying to maintain the peering connection to be
UP all the time even during the rerouting through alternative paths
is going on, you can do it with keepalive 0 as you said. No way else.

That; why cisco implmeneted the rerouting capable encapsulations:TCP,FST,
LLC2, TCP with RIF-passthrough to handle the re-establishement of the
peer while rerouting to alternative paths.
