This chapter describes how to configure IP routing on the Switch 9000.
It assumes that you are already familiar with IP unicast routing. If not,
refer to the following publications for additional information:
RFC 1058 —
Routing Information Protocol
RFC 1256 —
ICMP Router Discovery Messages
RFC 1723 —
RIP Version 2
RFC 1812 —
Requirements for IP Version 4 Routers
Overview of IP
Unicast Routing
The Switch 9000 provides full Layer 3, IP unicast routing. It exchanges
routing information with other routers on the network using the
Routing Information Protocol (RIP). The Switch 9000 dynamically builds
and maintains a routing table, and determines the best path for each
of its routes.
Each host using the IP unicast routing functionality of the Switch 9000
must have a unique IP address assigned. In addition, the default
gateway assigned to the host must be the IP address of the Switch
9000 router interface.
Router Interfaces
The routing software and hardware routes IP traffic between router
interfaces. A router interface is simply a VLAN that has an IP address
assigned to it.
As you create VLANs with IP addresses belonging to different IP
subnets, you can also choose to route between the VLANs. Both the
VLAN switching and IP routing function occur within the Switch 9000.
In Figure 8-1, a Switch 9000 is shown with two VLANs defined:
Finance
and
Personnel
. Ports 1 and 3 are assigned to
Finance
; ports 2 and 4 are
assigned to
Personnel
.
Finance
belongs to the IP network 192.207.35.0;
