INDUSTRY LEADING PERFORMANCE AND 
SCALABILITY
 
The BigIron RX Series is the industry’s most powerful switch 
family, delivering up to 3.2 terabits per second data throughput 
per system.
HIGH-AVAILABILITY DESIGN
 
Redundant and resilient design ensures high availability operation 
for demanding environments.
t
 Redundant, hot-swappable components provide non-stop 
 service 
delivery 
 – Management module: Systems configured with dual 
   
management modules with sub-second detection and fail-over
 – Switch Fabric Element Redundancy: Systems configured 
   
with a redundant switch fabric module support millisecond 
   fail-over 
performance
 – Hitless Management Failover (HMF): Stateful failover 
   
ensures that the forwarding engines on the line modules are 
   
not impacted by a management failover. This capability enables 
   
non-stop packet forwarding in the event of a management 
   module 
failover.
 – Redundant Power Supplies: All three chassis support M+N 
   
power module redundancy for AC and DC power configurations.
t
 Distributed Forwarding Architecture—Advanced network 
  processors, high-performance CPU and high-speed memory 
  on each interface module provide for a scalable high-performance 
 architecture 
 
t
 IEEE 802.3ad link aggregation up to eight links—Scalable, 
  cross-module trunking provides for resilient high-capacity 
  connections between switches. 
t
 Resilient Layer 2 and Layer 3 protocols provide fast service 
  restoration in event of link or equipment failures
  –  Metro Ring Protocol optimized for ring topologies, 
   
IEEE 802.1s and 802.1w for general Layer 2 topologies, 
   
VSRP for redundant switch configurations and VRRP/
   
VRRP-E for redundant router configurations, ECMP 
   
for routed backbones
ROBUST LAYER 3 FEATURE SET
Foundry’s IronWare software suite includes scalable EGP and 
IGP routing protocols.
t
 BGPv4—Scalable to 4 million routes, 500 peers and 14,000 
  attributes with MR2 management module
t
 OSPF—Scalable to over 400,000 routes
t
 IS-IS—Support for Level 1 and Level 2, includes 25,000 routes 
  and 512 adjacencies 
t
 Foundry Direct Routing (FDR)—The forwarding information 
  base (FIB) is downloaded to the hardware-based forwarding engine 
  on each line module. This memory can be pre-populated with 
  as many as 512,000 IPv4 and 64,000 IPv6 routes for wire-speed 
 routing 
performance. 
 
t
 Policy-based Routing (PBR)—Support customizable routing 
  policies using access control lists (ACLs). This feature can be 
  used to balance network usage by controlling the network paths 
  for different traffic flows.
t
 Comprehensive multicast feature set—Provides hardware-
  based support for a number of multicast protocols including 
  MSDP, PIM-SM (Sparse Mode) and PIM-DM (Dense Mode), 
  allowing network managers to efficiently deploy next-generation 
 multicast 
applications 
t
 VRRP and VRRPE (Enhanced VRRP)—Enables the BigIron 
  RX to operate as a backup router to other network routers. In 
  the event of a router failure, the BigIron RX will automatically 
  and seamlessly perform the tasks of the failed router.  
INDUSTRY LEADING LAYER 2 FEATURES
To provide self-healing topologies in Layer 2 configurations, 
the BigIron RX supports industry standard Ethernet protocols 
including Spanning Tree Protocol (STP), Rapid Spanning Tree 
(RSTP), per VLAN STP (PVST) and per VLAN group STP 
(PVGST). The BigIron RX also supports Foundry’s Metro 
Ring Protocol (MRP) for sub-second service restoration in ring 
topologies. Additionally, the BigIron RX supports multi-instance 
spanning tree, VLAN topology grouping and VLAN tunneling 
for advanced Layer 2 service configurations.  
t
 Metro Ring Protocol (MRP)—An alternative to Spanning 
  Tree Protocol, MRP provides sub-second fault detection and 
  fail-over for Ethernet ring topologies. MRP works in conjunction 
  with VSRP and 802.3ad based link aggregation to provide 
  bandwidth scalability and SONET-like resilience.
t
 Virtual Switch Redundancy Protocol (VSRP)—Supports 
  sub-second fault detection and fail-over for mesh topologies 
  in which redundant switches provide back-up operation for 
 one 
another
t
 Single-instance STP—Provides a single instance of STP to run 
  on all port-based VLANs within a single device, interoperable 
  with others that are 802.1d compliant
t
 Rapid Spanning Tree Protocol based on IEEE 802.1w
  Dramatically improves the spanning tree convergence time to 
  sub-second by automatically renegotiating port roles in case of a 
  link failure without relying on timers
