Cisco Design Advice

[Curiosityx]

Greetings, im half in the final stages of putting together an MPLS / Call Manager Express solution for several sites, the primary site is going to consist of an ASA5510 and a 3825 router running CME, the MPLS will be terminated on ethernet.

What i was wondering was whether to terminate the line on the ASA or the Router, ive currently specified it to be terminated on the ASA so that the router running CME sits on the internal network which i had envisioned it to be, for some reason im thinking this wont work but in theory it will, could anyone advise why this wouldn't be the case or am i going mad?!

Regards

Hi Curiosityx,

That should work just fine - I take it that the MPLS provider will be taking care of your routing tables / updates?

I implemented a similar solution for a remote site last year - though for some odd reason the CME hasn't really been used yet - the testing proved that it worked ok though

So you'd effectivly have the following:

MPLS CE Router > ASA > CME Router
___________________> Internal Network
(depening how you arranged your inside of the ASA - I terminated the CME on interface 2 and the internal network on interface 1, but it's up to you really!)

Indeed the ISP is running BGP within the cloud, thank you for your time
