The posts in the order the lab was built. Each one starts from the network the previous post left, on the same 25-node topology.
The Lab
Building a 25-Node CCIE SPv5.1 Lab
Part 1 – Foundation
- SP-A IGP Foundation: Multi-Area Dual-Stack OSPF for a Service Provider Core
- SP-B IGP Foundation: Dual-Stack IS-IS L2 for a Modern Service Provider Core
- IGP Optimization: Prefix Suppression, Overload Bit, LSP Fragmentation, and a little more
- SP-A MPLS Transport: LDP Label Ranges, OSPF Sync and Session Protection
- SP-B SR-MPLS: Predictable Labels, TI-LFA vs Classic LFA, and fragmentation problem
- The BGP Control Plane: iBGP Route Reflectors and VPNv4/v6 on One Session
- Convergence: BFD and Dual-Stack LFA on Both Providers
- Intra-AS L3VPN: Dual-Stack PE-CE OSPF and eBGP on Both Providers
Part 2 – Services
Coming next, mostly on SP-A: RSVP-TE with inter-area tunnels, SR-LDP interworking, VPWS and EVPN, a multicast core, and mVPN Profile 0.
The stage configurations for every post are in the public config repo.
