BGP — CCIE Enterprise Infrastructure
The complete BGP learning path for CCIE Enterprise Infrastructure: how sessions form, how prefixes are chosen and shaped, how the protocol scales with route reflection and confederations, and how it is designed, secured and repaired in production.

Stage 01
Foundations & Core BGP
What BGP is, how a session forms, how prefixes enter the table, and how the next hop is resolved.
- How a BGP session forms
- Loopback peering, multihop and authentication
- Advertising routes into BGP
- Reading the BGP table
- Why the next hop decides everything
Stage 02
Attributes, Path Selection & Policy
The attributes BGP carries, the algorithm that picks one path, and the policy tools that bend the outcome.
- The path attributes
- Why one path wins
- Hot potato and cold potato
- Filtering and route-maps
- Tagging routes with communities
Stage 03
Scaling & Architecture
Summarising the table, shaping the AS path, and the two ways BGP escapes the iBGP full mesh.
- Aggregating without losing the detail
- Shaping and matching the AS path
- Scaling iBGP with route reflection
- Splitting an AS with confederations
- Installing more than one path
Stage 04
Advanced BGP
Carrying more than IPv4, failing over faster than the default timers, and keeping the protocol from being abused.
- Carrying more than IPv4 with MP-BGP
- Failing over faster than the timers
- Making BGP harder to abuse
Stage 05
Design, Services & Troubleshooting
Putting BGP to work at the Internet edge, as the control plane of an L3VPN and an overlay, and repairing it in order when it breaks.
- Designing a dual-provider edge
- Carrying customer routes with VPNv4
- BGP as an overlay control plane
- Finding the fault in order
BGP Mastery
The end of the taught course. What remains is putting it together under exam conditions.
