limit to the settle time from the initial ROA table change even if

Default: 20 s.
<tag><label id="rtable-gc-threshold">gc threshold <m/number/</tag>
Specify a minimum amount of removed networks that triggers a garbage
collection (GC) cycle. Default: 1000.
<tag><label id="rtable-gc-period">gc period <m/time/</tag>
Specify a period of time between consecutive GC cycles. When there is a
significant amount of route withdraws, GC cycles are executed repeatedly
with given period time (with some random factor). When there is just
small amount of changes, GC cycles are not executed. In extensive route
server setups, running GC on hundreds of full BGP routing tables can
take significant amount of time, therefore they should use higher GC
periods. Default: adaptive, based on number of routing tables in the
configuration. From 10 s (with <= 25 routing tables) up to 600 s (with
>= 1500 routing tables).
