IP Link Primitive
IP link uses Apstra resource pool Link IPs - To Generics (by default) to dynamically allocate an IP endpoint (/31) on each side of the link. You can create an IP link for any routing zone including the default routing zone. You can use an untagged link even if it is for a non-default routing zone. If you select a tagged interface, the VLAN ID is required.
The IP link primitive ends with an ip_link point that can optionally connect to another compatible primitive, such as BGP peering (generic system).
To see the IPv4 address that's assigned, navigate to Staged > Routing Zones, then select the routing zone name in the table and scroll down to the Interfaces section.
