Description
Configure detection parameters in a network isolation group for an EVPN network. The device uses these parameters to detect network isolation condition changes. You also specify how long to delay before the device records and acts on a network isolation status change.
A network isolation condition means a bridge domain, VLAN, or EVPN instance (EVI) becomes isolated from the EVPN core network, usually for one or more of the following reasons:
-
The associated interconnecting physical or logical links are down.
-
The device doesn't have routes to the remote endpoints in the bridge domain, VLAN, or EVI.
You can configure either the link-tracking option or the
service-tracking option in a particular network isolation group,
and assign that group as a network isolation profile. You can't define link tracking and
service tracking parameters in the same network isolation group.
Options
| hold-time down milliseconds |
When evaluating the device has experienced a network isolation condition, the time the device waits in milliseconds before declaring the network is not reachable. Specify a value of 1 or more milliseconds. This setting is supported only with the |
| hold-time up milliseconds |
When evaluating if the device has recovered from a network isolation condition, the time the device waits in milliseconds before declaring the network is reachable and acting to bring up the associated interfaces. Specify a value of 1 or more milliseconds. |
You usually want to set a hold time greater than 0 so the device isn't excessively processing rapid status changes.
The remaining statements are explained separately. See CLI Explorer.
