Troubleshooting: BGP edge and EIGRP core
A branch's LAN never reaches the provider over BGP. Find the faults in the EIGRP core and the BGP edge and fix them.

Scenario
The branch (AS 65002) runs EIGRP AS 100 between edge router R2 and core router R3; R3 owns the LAN 192.168.3.0/24 and has a default route to R2. R2 should advertise 192.168.3.0/24 to the provider R1 (AS 65001) over eBGP, and R1 should advertise 203.0.113.0/24 back. Nothing works yet: PC3 cannot reach the provider server. There are several faults. Use `show ip bgp summary`, `show ip bgp`, `show ip eigrp neighbors`, `show ip route` and the running configs.
Your tasks
- The eBGP session between R1 and R2 is Established.
- R2 and R3 are EIGRP neighbours and R2 learns 192.168.3.0/24 from R3.
- R1 learns 192.168.3.0/24 by BGP and PC3 can reach the server 203.0.113.10.
The lab checks the result, not the exact commands. For example, a ping task passes only when the ping really succeeds through the network you built.
