IPv6 Static Route: Invalid Next Hop
IPv6 static routes follow the same forwarding principles as IPv4, but link-local next hops require an exit interface. This lab teaches both forms and when each applies.
The problem
R1 has a static route for a remote IPv6 LAN that uses an unreachable global next hop. The command is present, but the prefix is not installed and remote pings fail.
What you'll practice
- Read IPv6 static-route configuration
- Check IPv6 route installation
- Distinguish global and link-local next hops
- Verify remote IPv6 reachability
The topology
Two IPv6 routers share a point-to-point transit network; R2 routes to a remote /64 LAN.
