ENCOR lab 3
Mutual redistribution between OSPF and EIGRP
Join an OSPF domain and an EIGRP domain at a border router with two-way redistribution, avoiding the classic subnets and seed-metric traps.

Scenario
After an acquisition, the head office runs OSPF (R1) and the new branch runs EIGRP AS 100 (R3). R2 sits between them and already runs both protocols, but the domains cannot see each other. Redistribute in both directions on R2 so PC1 and PC3 can talk: every branch subnet, including the 10.0.23.0/30 link, must appear in OSPF, and the head-office networks must appear in EIGRP.
Your tasks
- R1 learns both the branch LAN 192.168.3.0/24 and the link 10.0.23.0/30 as OSPF external routes.
- R3 learns the head-office LAN 192.168.1.0/24 as an EIGRP external route.
- PC1 can ping PC3.
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.
