Use this dialog box to configure the ASN Range to assign Autonomous System Numbers (ASNs) for new appliances. Note the following before configuration:
ASNs are applied only to new appliances. The ASNs configured in this dialog box do not impact or change any previous or manually configured ASNs.
ASN Range is configured for Default Segment and cannot be changed.
ASN Orchestration assigns the same ASN to EdgeHA appliances.
ASN Orchestration assigns the same ASN to appliances with same site name.
Enter the start and end ranges for the ASNs. Click the +Add Reserved ASN to exclude any ASNs from being applied to an appliance. You can reassign ASNs manually by using the BGP tab.
