BGP path control with route-maps

Objectives

The simulator ticks each one as soon as the network meets it.

1. Peer R1 with R2 (10.0.12.2, AS 65002) and R3 (10.0.13.2, AS 65003); advertise 192.168.1.0/24.
2. Create route-map PREFER-B that sets local-preference 200, and apply it inbound from R3.
3. Confirm R1’s best path to 8.8.8.0/24 is now via ISP-B (10.0.13.2).
4. Create route-map PREPEND (set as-path prepend 65001 65001) and apply it outbound to R3.
5. Confirm R4 now reaches 192.168.1.0/24 through ISP-A and ping 8.8.8.8 from PC1.
