Rev 6.03
2.4.12 Software
The enhanced models of the GR2000 (GR2000-2S, GR2000-4S, GR2000-6H,
GR2000-10H, and GR2000-20H) use the same routing software called Routing
Software 2 (ROUTE-OS2). The conventional models of GR2000 (GR2000-4,
GR2000-10, and GR2000-20) use the same routing software called Routing Software
(ROUTE-OS).
With GR2000-6H, GR2000-10H and GR2000-20H, IP-VPN function utilizing the
MPLS function and MPLS can be used by applying the basic plus expansion software
(Routing software3 : ROUTE-OS3) in place of ROUTE-OS2 or ROUTE-OS. This is in
addition to the function provided by the common software (Routing software2:
ROUTE-OS2) or (Routing software: ROUTE-OS). Moreover, in GR2000-2S,
GR2000-4S, GR2000-6H, GR2000-10H and GR2000-20H, an IPv6 relay function can
be used by applying basic + extended software 6 (routing software: ROUTE-OS6).
Embedded BSD/OS is used as an Internet server and kernel in the RM. Various
protocol functions and commands are packaged as separate application processes to
provide scalability. Included in the path control is the commercial version of GateD,
which runs routing protocols such as OSPF and BGP4.
Figure 2-39 shows the composition and functions of the routing software.
