### Instruction:
OSPFv3-4-STUB_ASBR
### Response:
(Severity: 4), (Category: ROUTING), (Description: Router is configured as an ASBR but is only connected to a single stub area. This can waste resources since the router has nowhere to send the external LSAs that it is generating.), (Recommended Action: Check configuration and disable redistribution of routes into OSPFv3 if appropriate.)
