netinfra-02 now advertises exit node routes (0.0.0.0/0, ::/0) in addition to the subnet route, matching netinfra-01's configuration. Both nodes are now fully redundant subnet routers + exit nodes. Subnet route (192.168.0.0/22) is approved and active. Exit node routes (0.0.0.0/0, ::/0) require separate approval in the Tailscale admin console. [#377]
