Our company is planning to migrate all our point-point curcuits to MPLS.
As a customer, I would like to understand more about how the ISP will provide this service? Will they install a router at our site and provide us with an ethernet handoff to our own router?
Is the bandwith scalable to any size we want? Will they accept OSPF from our network? Any documents would be appreciated.
Well.. it depends which provider you are talking about.. i haven't seen one running OSPF between CE and PE yet.. but from an config standpoint it's possible.
Most of the times they have an BGP peer between your CE and their PE and you have to run both protocols and perform mutual redistribution.
You can specify the bandwidth, but it will be up to the provider what was the link you ordered.
Hope that helps.
I think his question is more related how this setup between his CE router and the ISP would work?
Briefly, in the most of cases you won't be running MPLS over our CE router. Usually, you would have an simple EBGP peers with the provider and in this case the provider is the responsible to route your network over their MPLS backbone.
Does that makes sense?
