Hard interface shutdown when a device detects EVPN core isolation conditions

You can configure a device to bring associated interfaces down (hard shutdown) when the device detects an EVPN core isolation event.

In the CLI:

1. Define a service tracking profile for detecting core isolation conditions.

2. Set the link-down service tracking action in the profile.

3. Assign the profile to the interfaces you want the device to bring down after it detects a core isolation condition.

We support core isolation service tracking on:

• Links to single-homed customer edge (CE) devices.
• Ethernet segment identifier (ESI) LAG member interfaces to multihomed CE devices.
