Goal : R1 (IPv6 2000::1) is able to ping R5 (IPv6 4000::5) and vice versa. IPv6 Network using RIP as routing protocol and IPv4 using OSPF. No direct link between R2 & R4, using tunnel interface instead.
Scenario :
- Create IPv4 & IPv6 addresses on each router as picture above
- No need to config IPv6 in R3 & there is no directly connected link between R2 & R4
- Create OSPFv2 and advertise IPv4 network address in R2, R3, R4
- Create tunnel interface mode ipv6ip (default mode is GRE) in R2 & R4,
- Tunnel source is Lo1 for R2 & R4, and make sure tunnel destination addresss is reachable.
- All RIPng routers should reachable by each other.
- Verify : show ipv6 route, test ping / trace IPv6 address from R1 to R5 and reverse
Configuration :
- OSPF Config R2,R3,R4
