Hi
I have 6 routers in 6 cities interconnected by 1Gbps links from third party
providers (just 1 VLAN over xconnects, no QinQ, MTU=1500). Each city is
connected to main node. I have to distribute multicast streams (around 100
channels of IPTV) from source 1 city to 5 others over these 1Gbps
Hi all,
The entire picture includes trunk port with 2 unicast and 1 multicast
VLANs and the goal is to do a traffic policing to the multicast one.
I can not perform per port - per vlan policing so I created SVI
interface, configured the trunk port as mls qos vlan-based and expected
that

How do this best ? Use mBGP ? Use MSDP ? Configure just PIM-SM on
backbone
interfaces ? Or maybe some hybrid solution ?
You just need PIM-SM.
Designate one router as the RP. Configure PIM-SM each router. Configure
them all with the same RP.

Hi folks,
Would You consider an ASR 9K as a reasonable (money and tech-wise) upgrade to
Cat7600? I understand that ASR9K scales way better than c7600, and there should
be lots of other reasons why ASR9K would be more appropriate for SP core
network... but I just can not gather enough arguments
The 9K is an evolution of the 7600.
The biggest differences are the newer DFC components and the XR code.
The down side is the 9K is relatively new so there may be more bugs.
And there are always plenty of bugs.

You mention you're using iSCSI.
What utilisation rates are you hitting? The 3750 has pretty small
per-port buffers, so if you are contending one or more ports, you could
be getting packet loss due to that.
e.g. you boot a machine, it hits a disk very hard over iSCSI, causing
contention and packet
I believe the greatest difference which _may_ or will happen will be its
roadmap on the 100G cards ?
I doubt it'll be happening on a 1:1 basis on the 7600, you may want to verify
with your Cisco account rep.
Nothing is bug free, which includes printing hello world. look at the
brighter side,
The faster backplane is a long term advantage.
The current advantages are pretty minimal.
There really isn't a good business case to upgrade at the moment.

Hi All
Can some one please suggest me a good book to study about the DSL

Out of print and a little outdated for cutting-edge stuff, but X-DSL
Architecture by Padmanand Warrier is an excellent book
So far I've received several ideas:
- Go for Juniper's MX series. Technicaly - yes, MXes are good, politicaly - no,
I'd like to stick with Cisco and evaluate ASR9K pros/cons;
- Go for Nexus 7K. Politicaly - yes, technicaly - no no no, as Nexus series are
excellent for DC deployments but
Andris,
MX's are decent devices, however I would say that the 9K has on-up'ed
Juniper on this.. I have experiences with both platforms and working with
them both, the MX is definitely outdated. However their new Trio 3D
linecards are bringing the MX back into the new-age a bit. I would agree
with
On a lighter note,
Not sure why you want to aproach the problem logically and from
technology viewpoint, the people you are going to speak to are not
going to understand your argumentation anyway :)
I suggest you use some slides from this link I found on google
there should be lots of other reasons why ASR9K would be more appropriate for

ASR9K gives good NetFlow, 7600 doesn't.
ASR9K doesn't have weird ACL-construction caveats, 7600 does.

I understand why that would appear to be the case, but the reality is that
ASR9K and 7600 have absolutely nothing in common, from OS to ASICs to
Asr is a router from the start. 7600 was a switch from the start. Totally
different approaches.

mostly - it's getting there (e.g. doesn't support destination based netflow
for ipv4, or either peer-as or destination AS records for v6) But it
doesn't have the awful limitations of the sup720 in this regard.

Just a quick question:
Why are the 3745's so inexpensive? I am seeing them go for about $175
base price (128MB RAM/ 64MB flash, 1 power supply) on that auction
site and other places.
Is there a feature that Cisco is not supporting on them? Do they have
high rates of failure that make them

Hi,
I'm trying to figure out if BFD is supported on a PortChannel
interface on IOS-XE (3.1.0S) on ASR1006. Configuration is accepted but
then the session never comes up:

Thanks for your response Jason.

Hi
I have very basic question. Sorry for this.
How I am able to see traffic (source IP, destination IP and port) which is
passing from Cisco routers, from specific interface or as a whole.
Which is easiest and troubleless way to achieve this. Kindly also guide me

If you do not need the MLS capabilities of the 7600 such as SVIs, then the
ASR9K is a good box. The ASR9K should be able to solve that problem in
the future, but a loopback cable is the current solution. :) The routing
table capacity isn't huge for both V4/V6 combined but it's adequate until
