Hi,

I currently have a Frame Relay network with central site and 22 remote
locations, coupled with ISDN backup. The system works fine, but now our
telecom provider has new service.



They have MPLS backbone, and they are offering IP VPN connections as a
replacement for our current network.



I spent several days in research for this new opportunity and I see that
obviously this is a better offer. We will start a test period in which we
are supposed to connect several locations just to compare with the Frame
Relay.



Now here are the questions:

1. I have problem with understanding the configuration of the customer
(mine) router. I have read many papers about configuring the PE and P
routers in the MPLS backbone, and the PE interface to the CE router, but I
haven't found a paper describing the configuration of the CE interface to
the PE router, nor I have found an example of it. Can someone point me or
explain the configuration of the IP VPN interface. Are there any examples of
it or comparison with the Frame Relay configuration?



2. The current situation is with ISDN backup lines which are configured with
static routes and Frame Relay end-to-end keepalive parameters. This
eliminates using dynamic routing protocols (ex. RIP, OSPF...). Regarding the
previous question and this statement, are there any possibilities of keeping
the static routing or should we definitely turn to a dynamic routing
protocol.



Best regards,

Aleksandar
