usr.sbin/ldpd : hello.c ldp.h ldpd.conf.5
Log message:
Validate received hello holdtime and keepalive time.
Refuse a keepalive time of zero because it's invalid. For the hello
holdtime, zero is valid and means infinite.
Additionally, refuse values smaller than three for both the keepalive
timer and the hello holdtime. The keepalive/hello interval is calculated
as one third of their holdtime, which means that if the holdtime is one
or two, the calculated interval would be zero using integer arithmetic.
If anyone wants to use such a small holdtime, he or she should use
BFD instead.
