ospfv3 frr block

Function

The ospfv3 frr block command blocks FRR on an OSPFv3 interface.

The undo ospfv3 frr block command restores the default configuration.

By default, FRR is not blocked on an interface.

Usage Guidelines

Usage Scenario

To prevent the link that travels through the devices running important services from becoming a backup link, run the ospfv3 frr block command on the devices. In this manner, services on the devices are not affected when FRR calculation is performed.

Precautions

Before configuring OSPFv3 IP FRR, you need to run the ospfv3 frr block command to block FRR on a specified interface. In this manner, the link where the interface resides is not calculated as a backup link during FRR calculation.

Example

# Block OSPFv3 IP FRR on GigabitEthernet 0/1/0.
