The Juniper M7i is a legacy multiservice edge router offering flexible interface expansion, modular services, and strong IP/MPLS performance in a compact chassis. It was widely used in small PoPs, enterprise WAN edges, and campus border roles but has since been superseded by newer generations of Juniper routers.
Product Overview
The M7i is the most compact routing platform in Juniper’s M-Series lineup, optimized for small Points of Presence (PoPs), enterprise edge, Internet gateway, or campus border roles. It runs Juniper’s JUNOS Operating System, delivering consistent IP/MPLS routing and service features across M-Series routers.
Key Features
• Compact Chassis:
• 4 PIC (Physical Interface Card) slots for flexible interface expansion.
• Fixed interfaces vary by model — options include 1 or 2 Fast Ethernet ports or 1 Gigabit Ethernet port on the base unit.
• Performance:
• Up to 10 Gbps throughput, suitable for edge routing and aggregation workloads.
• Capable of handling up to 16 million packets per second (Mpps).
• Routing & Services:
• Full IP/MPLS feature set supported via JUNOS, including standard Layer-3 routing protocols.
• Optional Adaptive Services Module (ASM) available — adds hardware-accelerated services like NAT, stateful firewall, IPSec VPN, and flow-based accounting when installed.
• Flexible Interfaces:
• Supports a range of interface cards including Fast Ethernet, Gigabit Ethernet, ATM/SONET PICs depending on deployed modules.
• Enterprise & SP Applications:
Suitable for:
– Small service provider PoPs as an IP/MPLS edge router.
– Enterprise WAN edge or Internet gateway.
– Campus border/router aggregation roles.
