Re: [AFMUG] MPLS for non-redundant paths

[Carlos Alcantar]

MPLS TE (traffic engineering) is widely used in large networks.  It can add a 
layer if complexity so your milage may vary and may not be worth the time and 
energy of having to deal with this other abstract layer.

Subject: [AFMUG] MPLS for non-redundant paths

If I have a hub-and-spokes topology I want to do some traffic engineering on to 
avoid congestion, is there an advantage to MPLS over just using separate 
subnets to ease congestion if I don’t have multiple redundant paths that I need 
to be able to route around? I understand there is advantages if you have 
multiple paths to the endpoint, but this wouldn’t be the case here.

I also would like to move routing out closer to the edge. What are the real 
benefits of MPLS in either case?

[AFMUG] Verizon Unlimited coming back

[Darin Steffl]

So tomorrow, Verizon launching an Unlimited cell plan like the other 3 big
carriers. Full speed up to 22GB, then will only be slowed if a certain
tower is congested. 10GB mobile hotspot included with 4G, then drops to 3G
after. Includes Mexico and Canada roaming up to 500MB per day.

$80 for single line.
$45 per line if you have 4 lines.

They lost quite a few postpaid customers last quarter and this seems to be
a response to them losing customers to the other 3 carriers. So now all 4
national carriers have an unlimited data plan with caveats of course.

Re: [AFMUG] odd mt behavior

[Larry Smith]

Agree with Faisal, proxyin arp turned on somewhere.
Track the MAC address that is replying to all the ARP
and you will find your culprit.

Re: [AFMUG] odd mt behavior

[Faisal Imtiaz]

We have seen that behavior from misbehaving sonic wall (firewall) 
and some implementations of consumer firewalls (Watchguard, Sonicwall etc) will 
do this when the proxy arp is set to be on.

Re: [AFMUG] odd mt behavior

yeah...tracked it to arp table full...something is flooding the arp list
with every unused ip.
