Usage guidelines
Isolation is a method used for network device maintenance. It gracefully removes a device from the
packet forwarding path for maintenance and gracefully adds the device to the network after
maintenance.
To reduce impact on traffic forwarding, you can isolate a device before upgrading it. OSPFv3
isolation works as follows:
1. After OSPFv3 isolation is enabled for a device, OSPFv3 increases the link cost in LSAs
advertised by the device based on the following rules:
The link cost in Type-1 LSAs (Router LSAs) is set to 65535.

The link cost in Type-9 LSAs (Intra-area-prefix LSAs) that reference Type-1 LSAs is set to

65535.
The link cost in the following LSAs is set to 16711680:
