Usage guidelines
You can use the stub-router r-bit command or stub-router max-metric command to configure a
router as a stub router.
•
The stub-router r-bit command clears the R-bit of the Option field in Type-1 LSAs. When the
R-bit is clear, the OSPFv3 router can participate in OSPFv3 topology distribution without
forwarding traffic.
•
The stub-router max-metric command specifies the OSPFv3 max-metric router LSA feature.
This feature enables OSPFv3 to advertise its locally generated Type-1 LSAs with a maximum
cost of 65535. Neighbors do not send packets to the stub router as long as they have a route
with a smaller cost.
