A "soft" reset is generally only seen from the end doing the reset.
IIRC, a soft reset withdraws all the prefixes and re-announces the new
set of prefixes. There's really no way to detect that.
You could monitor the number of prefixes you are receiving and take
action if that falls below a certain amount.
