[nsp] ios ntp

[Marcus Keane]

Firstly, I'm not an expert in NTP so bear with me. But the problem is
that it is built into the design of NTP that a server can lose
connectivity to it's upstream server for 24hrs and still have downstream
clients pass sanity check 6. So in the case of the router/server that
has synchronised within 24hrs it will serve and the downstream
client(router?) sanity checks will pass. 

But if your router/server hasn't synced ever or within 24hrs then it
will still serve but these packets will fail sanity checks on the
downstream client.

hi there,


is anyone aware if it's possible to set ios built-in ntp server to serve
only if it is synchronized to a higher-stratum peer?


thanks

A transistor protected by a fast-acting fuse will protect the fuse by
blowing first.
