• Performs Layer-3 switching across 4-16 adapter slots, depending upon router model
• Supports large suite of dynamic routing protocols
• Accommodates multiple types of media, including HSSI, 10/100Base-T (fast Ethernet),
ATM OC-3c, ATM OC-12c, SONET OC-3c, HIPPI, and FDDI
• Provides basic filtering, OSPF multicast, SNMP v1

Figure 1-1. Connections between the SP Switch Router and an SP system
Configured with an IBM SP system, the SP Switch Router provides multiple media LAN and
WAN connectivity for the SP. The SP Switch Router Adapter card connects directly to the SP
Switch. Other components communicate across the administrative Ethernet network.
(While using a hub or a bridge to interconnect the administrative Ethernet segments is
common, other network components can be used to provide connectivity between the
segments.)
