NTP implementations all tend to "resolve at start, and never again".
Cisco does it that way, standard unix ntpd does, ...
I wouldn't ever do a stackable for a core, that is just asking for
down time for various scenarios for no appreciable reason. If anything
the 4948 is an upgrade for the 3xxx gear. I would also suggest either
the X or the n5600 like two previous suggestions, with leanings to the
n56 depending on wha
Thanks very much for the infogot a couple of 4500X's(In VSS, and hasnt

to go with what you have described...just would mean replacing all the e

You can never assume that windows does anything correctly.

I guess I assumed windows using DNS correctly was wrong. There is a way to
flush dns (I think it’s ipconfig /flushdns) but it really shouldn’t be

I can live with that :-). The concept is still the same, just that SVI's
are replaced with BDI's.
I can imagine how hard it would have been to find this out on the back
of poor documentation.

TTL is 1 hour. this lasted over 2 weeks before we changed from FQDN
to IP. which corrected the problem.

What was the TTL of the DNS entry? I'm assuming windows DNS respects TTLs
and re-polls when it expires?

we ended up changing the NTP FQDN to the IP and restarted services and it
fixed it. It's like the FQDN only gets resolved once and never again. So
after changing it to the IP I'm guessing I could change back to the FQDN.
we were just hoping that changing the DNS was going to fix it.

Why would it? You could simply dual stack your CPE handing out 100.x.y.z
CGN prefix IPv4 addresses and a public IPv6 address/prefix.
Hello,
I've not been able to find any references on cisco.com so i'm asking
here before reaching TAC.
As per my understanding IOS-XE does not support RT constrained route
distribution (address-family rtfilter / RFC4684 ) for VPLS NRLIs
(AFI=25, SAFI=65).
Is it a bug or a (missing) feature?
Dear,
Perhaps I will say mistakes, but I can read :

Rancid seems to work well for our network. We can get the location of any
serial number from the history in CVS as an example.
