- You're creating a multi-AS BGP test lab on Sunday evening;
- The core AS is running 12.2SRC code;
- You insert a P-router in the core network ... because every large network has P-routers;
- You create BGP session templates instead of configuring two parameters of a few IBGP neighbors;
- You configure MPLS in the core network instead of using BGP on all routers ... because it saves you a few BGP sessions ... and that's the way things should be done anyway;
- When configuring OSPF, you define inter-AS links as passive interfaces ... not because you're running OSPF in the other AS but for security reasons :)
