Compact 400G-Ready Edge & Aggregation Platform
The Juniper MX304 is a next-generation, compact 1RU routing platform that delivers
extraordinary 100G/400G density for edge, aggregation, and metro networks. As part of the
MX Series Universal Routing Platform, the MX304 offers powerful forwarding capabilities, advanced
5G-ready features, and energy-efficient performance in the smallest MX form factor ever produced.
BrightStar Systems supplies fully tested, used and refurbished Juniper MX304 routers that deliver
high-capacity routing at a fraction of OEM cost. Each platform undergoes complete port and performance testing
and is backed by our in-house warranty for reliable deployment in production environments.
Why Choose the Juniper MX304?
The MX304 is one of the most efficient high-density routers on the market, offering:
Up to 4.8 Tbps of throughput in a compact 1RU design
8 × 400G QSFP-DD ports and 16 × 100G QSFP28 ports (model dependent)
Optimized for edge, metro, 5G transport, and peering applications
EVPN-VXLAN, MPLS, Segment Routing, SRv6 support
Redundant power supplies & fans for continuous operation
Lowest power per 100G port in its class
The MX304 is ideal for providers and enterprises needing large-scale 100G/400G capability
without moving to a full-size chassis router.

Frequently Asked Questions
Does the MX304 support EVPN-VXLAN?
Yes — the MX304 fully supports EVPN-VXLAN and can act as a VXLAN gateway for modern data center fabrics.
Can you mix 100G and 400G ports on the MX304?
Yes. Depending on the model, the MX304 supports mixed configuration of
QSFP28 100G and QSFP-DD 400G ports.
Is the MX304 suitable for 5G transport?
Absolutely. Its high throughput, compact footprint, and Segment Routing (SR-MPLS and SRv6) support
make it an excellent 5G edge and metro routing platform.
Is the MX304 quieter and more power efficient than older MX routers?
Yes—it’s one of the most power-efficient 100G/400G routers available and significantly quieter than larger chassis systems.
