Link between the syslog server & device fails then syslog message fails. Syslog: If the router is set up to send logs to a syslog server, you will see some information on what happened before the crash on the syslog server. However, when the router is crashing, it may not be able to send the most useful information to this syslog server. So most of the time, syslog output is not very useful for troubleshooting crashes.
Yep, totally agree and understand, but most or less I have customer that part of their security requirement is if a device stops logging they want to know about it.
The only thing that I can think of is writing a script to sent a syslog message back to the syslog server and if it receives it then great. If not then alarm or try again then alarm... I was hoping that someone else might have this requirement too.
Pre-12.4T, set up an IP SLA monitor performing ICMP path echo (ping) against the syslog server, then have an EEM policy fire off heartbeat syslog (action_syslog) loosely according that. With 12.4T, send the same heartbeat syslog from IOS tclsh using the opaque write-only file system. Then it's up to the log-watcher software on the syslog server to "monitor" who's checked in and who's not.

Introduction The purpose of this document is to demonstrate the Open
Shortest Path First (OSPF) behavior when the V-bit (Virtual-link bit) is
present in a non-backbone area. The V-bit is signaled in Type-1 LSA only
if the router is the endpoint of one or ...
