Dear Experts,
I am working on an MPLS core design for an ISP out here in Africa. I have two
types of customers that require internet access via the MPLS core.
1. MPLS VPN clients that connect via a 3800 CE router (PE - CE routing
protocol is OSPF)
2. Broadband clients that terminate on a Cisco 7609 (with Cisco MWAM module
configured as PDSN)
Below is a schematic topology of the MPLS design
Broadband _____________
Client -------------> | PDSN (7609) | Global routing
_________________________________________
|____________|
-------------------------------->|
|
|
|
|
|
| MPLS CLOUD | -------> INTERNET (VPN or GLOBAL)
_____________
| |
MPLS | Cisco 3800 | VRF VPN_A |
|
Client -----------------> | CE Router |
---------------------------------->|_________________________________________
|
|____________|
My Challenge however is how to configure the internet link whether in a VPN or
global routing table to give access for both broadband and MPLS clients.
Thank you for your advice
