how to tell is device is PE or CE

[mike18]

Hi Everyone,

I am new to Alcatel 7750.In our current environment I see that we are running VPRN on top of VPLS.
We have remote sites running 6800 switches and core site uses 7750SR.

In between we have MPLS cloud.

Need to know which command or config I can check on 6800 or 7750SR to know which device is CE or PE?

Regards
Mike

The common definition of a MPLS PE router is that it is at the edge of your MPLS network, sending unlabelled traffic towards the CE and labelled traffic towards your core.

So one simple way for your example is by checking if the router is running MPLS. So on the 7750, something like "show router mpls status" or "show router mpls interface". The PE will have MPLS enabled on the interface towards the core and not on the interface towards the customer.

Or check LDP
show router ldp interface
If youre really bleeding edge you may be running segment routing.

If you are using a VPLS and the middle is a 3rd party providers MPLS network then your devices will be CEs as VPLS is an L2VPN and your VPRN might be considered vrf lite.
