MPLS

[teltac]

Hello,

we r ISP and we need to migrate to MPLS.We r planning to provide MPLS VPN , MPLS TE, End to end QoS , attacks Restrictions ( coming from outside and from our registered Users) .

we r running a Catalyst 5509 as a backbone Layer 3 Switch ( serving our corporate users) and two Cisco router 7206 vxr with NPE 400 ,one is serving as a Main Gate and Broadband access aggregator for our PPPoE clients and the second one is used as LNS( terminating L2TP tunnels) for our dialup customers.

i am asking what we need to build a MPLS backbone ? could it be done with the actual devices used ?

then how the feature above will be provided to our customers ?

any Basic Docs or urls that elaborate MPLS plus implementation , configuration and benefits will be an assest.

Thanks & Best Regards,

Ali.

I think the 7206 provides MPLS support, but doubt whether the 5500 does. Check out this page for more info :

7206 supports MPLS, although if you need AToM, you have to run 12.2S.

Are you sure you need MPLS?

MPLS is just another switching method.

IF you need TE, thats a good reason to switch to

MPLS.

It seems to me that the equipment listed will not

be sufficient to implement MPLS.

I mean of course you'll be able to run it on 72xx

but does running MPLS on 2 boxes, make you having MPLS backbone?

But again with the 2 72xx you can do MPLS TE,

if that is your aim.

I would advise going and bying a very good book on the MPLS:

MPLS by Yakov Rekter and Bruce Davie.

One of the best books I have ever read.

Very simple and clean discussion on the

MPLS, FIB, etc.

Here is the Link on the amazon.com

So again, before doing anything first try to understand what you would like to acomplish with the MPLS, then do a change proposal and

estimate the affected users/downtime/risk.

i will try to get book .

Thanks anf Regards,
