The diagram is the same as my last VPN Lab. Also it uses my MPLs topology found over here: http://mellowd.co.uk/ccie/?p=522
This is the topology for this lab (click for a bigger image):
- Customer1 and Customer 2 both have MPLS vpn’s through the ISP core.
- Customer1 is using OSPF and Customer2 is using EIGRP
- Customers should have no access to each others networks
- Customers should be able to reach all their sites from all their sites
- The ISP wants to monitor the CPE routers via their monitoring server. Create another loopback on each CPE router and give them all a /32 loopback in the 172.16.1.1/24 range – i.e. 172.16.1.1/32 for CPE1, 172.16.1.2/32 for CPE2 and so on
- Ensure the monitoring router can get to all these /32 routes (and ONLY these /32 routes) – It should not know about any customer routes – CPE routers should only see their OWN loopbacks in the routing table
- Now enable CPE3 and CPE6 to see each others subnets. All other CPE routers should see no change in their routing tables
