Do you mean "Full routes" for BGP ?
Sometimes there are extra charge for BGP, but never heard about full
routes or not.
How can they guarantee whether they provide Full routes or not ?
If some routes are missing, are they going to provide the credit for it ?
Full routes from BGP is always best-

If there is DDoS attack going on from/to specific /32, sometimes they do

What about 7600-S models ?
I think Cisco is claiming that Cisco 7600-S (7606S, etc...) chassis is
ready for less than 50 ms switching time with right software.
For routing, you can setup graceful restart or something like that.
For Cisco ASR9000, I couldn't say much, because it is new product.

What if there is a problem from software, filter, mis-configuration from
one of the routers ?
It will affect whole ring network, not just that problem router.
Also if there is routing protocol bounce because of link flapping, it
will be propagate through the ring forever.

It really depends on your application server configuration.
Most people just uses SNMP for this purpose.
Something like net-snmp installed in servers, then monitor the info via
SNMP MIB polling.

About 3 months ago, Cisco Account Team was recommending AS14000 for our
company, and we rejected it.
Poor product development management!

Because of nowadays network scalability demands, Cisco is preparing ASR
14000 series to replace this one, I think. ^^
Basically ASR 14000 is downgrade version of CRS-1, but I consider it is
still developing or beta product.

If it is the way AT&T have designed their product, there may be no other
way around.

If you pay extra, AT&T may have some solution for you.

6) local regulation such as fire department safety rules...

If you want better, why not just have everything to DC power ?
Something like 48V...

I don't think there is no real answer for your question.
It depends on each company's business objective, the cost, network
topology, and their policy.
MX record is the the mechanism for mail delivery procotol.
It doesn't dictate how to implement.
Depending on mail volume, and network policy, you
ASR is embedded linux solution with Quantum Processor architect if I
remember correctly.
So it uses IOS-XE, which is a little bit different from standard IOS.
If you have some room for budget, you can check Foundry MLX/XMR series
router.
It is more geared toward Ethernet Service Router.
But if y
Cisco 7304 may not adequate for service provider.
It's CPU/IO-controller is tied together, and doesn't provide much of
benefit.
Cisco 7200/7300 is enterprise solution pretty much, and doesn't support
distributed CEF.
If you are considering SUP720-3BXL, why not considering RSP720-3CXL ?

Unless you configure Layer 2 for two interfaces, it's not going to work.
It is invalid from networking principle.
If you have to send the traffic for host in same subnet you configured,
which interface it should send out ?
Basically it may create broadcast storm loop by putting two ip addresses
in
Theorically it's doable.
But mostly No to your questions.
IXP means Internet eXchange Point.
So it is public Internet. Why do you want to use private IP address ?
Most RIR allocate /24 unit for IXP.
For troubleshooting purpose, it is better to use public IP address as it
is designed.
Unless you w
maybe host problem?
I can reach to www.level3.com, but not www.level3.net.
It seems both are belonging to same subnet.

Not all of Cisco IOS supports 4-byte ASN.

I think it is really depending on what kind of provisioning system you
have.
Circuit ID is determined by your provisioning system for CLR/DLR reference.
As long as you can find circuit info quickly, it doesn't matter that much.

Also one of the reason why not putting default route may be because of
recursive lookup from routing table.
If you have multi-homed site within your network with static route, and
if you use next-hop IP address instead of named interface, you will see
the problem when you have default route in rout
It may be.
If the customer is BGP customer, and they have connectivity problem,
your traffic will flow into Verizon since Verizon have supernet.
But within Verizon network, Verizon router doesn't have specific route
info to route into.
So you may see time-out as soon as it hit Verizon network.
