About the ACX5448-R-DC-AFI
ACX5448-R-DC-AFI is the fuller bundle: a 1U DC router with 48 SFP+ ports and 4 QSFP28 ports that includes L2, IGP, MPLS and BGP. The 48 10GbE ports, the 4 100GbE ports and all 1GE, 25GbE and 40GE ports are covered, and FIB and VRFs go up to the system limit.
Air enters at the power-supply side and leaves at the port side. Because rights are in the bundle, a typical metro design needs no extra feature license to start.

Common questions
Does it need a license for MPLS or BGP?
No. The bundle includes MPLS and BGP rights, along with L2 and IGP. FIB and VRFs are covered up to the system limit.
How is this different from the ACX5448-A-AC-AFO bundle?
The A bundle is AC powered and carries only L2 and IGP with a 256K FIB. This R bundle is DC powered and adds MPLS and BGP.
Can I still add Advanced or Premium licenses?
Yes. Those tiers, other right-to-use options and Juniper Care are listed in Support & Licensing above.
