Thamir,

For the most part, vendor products are RFC compliant should interoperate.

However, in some cases they do not. In particular, If you are running LDP

pay attention to “modes of operation” which is simply: DU vs DoD, Ordered vs Independent, and Conservative vs Liberal retention.

Some combinations may cause abnormal behaviour in regards to label binding and release.

Thanks Padmini for your prompt replay,

But what services you are running? Any NGN?

Do you have mix of PEs? Or mix of Ps (mix in the core)?

 

Br,

Thamir

Yes of course its practical.  We in India very much have this kind of configuration and things work fine provided you find the compatible routers.

Hi,

 

I want to know your opinion regarding running MPLS from multi-vendors, is it practical? I mean the PE from vendor and the P from other vendor or  mix of PEs and Ps from different vendors? Specially, in NGN environment where no doubt about TE, QoS, L2VPN & multicasting.

I am afraid about this because I think any of these technologies still draft in IETF and there are different philosophies from different vendors.

 

Do you know any case which successful or failed? Any white paper? What is the possible risk?

 

Br,

Thamir  Alhammad
