This is my first lab to use my MPLS topology found over here: http://mellowd.co.uk/ccie/?p=522 (Click the link as you’ll need the core ISP set up to run this lab)
This is the lab topology – click for a larger image:
- Use RIP as the routing protocol on CPE devices
- CPE1 and CPE5 belong to Company_A
- CPE2 and CPE6 belong to Company_B
- Each site has a /24 that is advertised via the loopback
- CPE1 should be able to ping CPE5′s loopback and vice-versa
- CPE2 should be able to ping CPE6′s loopback and vice-versa
- Different companies should NOT be able to ping each other. They must stay completely separate
- Now remove RIP and configure it so that both companies are using OSPF
- Once complete, remove the OSPF config and use EIGRP
Solution is now here: http://mellowd.co.uk/ccie/?p=570
very good
