iBGP
Assignment
Goal: Configure iBGP in the Moscow office, configure iBGP in the Triada provider network, and establish full IP connectivity across all networks.
- Configure iBGP in the Moscow office between R14 and R15
- Configure iBGP in the Triada provider network
- Configure the Moscow office to prefer Lamas as the primary provider
- Enable iBGP in the St. Petersburg office (without using OSPF)
- Configure the St. Petersburg office to load-balance traffic to any office across both uplinks simultaneously
- All networks in the lab must have IP connectivity
- Document the plan and changes
iBGP — Moscow (R14 ↔ R15)
iBGP session uses Loopback0 addresses reachable via OSPF area 0. next-hop-self ensures the iBGP peer can reach external next-hops.

Moscow — Lamas as preferred provider
R15 marks all updates from R21 (Lamas) with local-preference 150 at ingress via route-map LP. This preference is then propagated to all iBGP peers — R14 sees LP=150 for Lamas-learned routes and prefers them over Kitorn paths. A filter-list restricts outbound announcements to only locally originated prefixes (^$).

Note: Setting local-preference at R15 ingress (instead of outbound from R14 toward R15) is the scalable approach — R15 propagates LP=150 to all iBGP peers automatically. (Thanks to Alexei for the consultation.)
iBGP — St. Petersburg (AS 2042, no OSPF)
EIGRP is used for loopback reachability within the office. iBGP sessions run between all four routers using loopback addresses.
