Yes, absolutely.  Just the other day I fixed a bug that was causing
routers to fail to send the "infinite-hop" full linkstate updates.
Eventually, important foreign linkstates (especially "backplane"
linkstates) would expire, and the routing would unravel.

hslsd will write its IPv4 & IPv6 routing tables in /var/db/routes
every few seconds or when you send a SIGUSR2, e.g., pkill -USR2 hslsd.
hslsd writes the linkstates to /var/db/linkstates at the same time.
This all happens "atomically," so the two dumps will be consistent with
each other.  The routing table in /var/db/routes is good for comparing
with Zebra's routing table (telnet localhost 2601; show ip route) to
make sure that Zebra and HSLS agree.

The ping test only affects whether we advertise a default route to
other routers using HSLS.  It cannot be disabled.

BTW, I have decided that advertising with HSLS any RFC1918 subnet other
than the ones a CUWiN network synthesizes is sufficiently evil that I
may stop doing it.  Actually, I may have already stopped doing it.
