Chapter 6
Inter-VLAN Routing
To configure a default gateway on a 5000 series switch, use the set ip
route
command:
Todd5000> (enable) set ip route 0.0.0.0 172.16.1.1
Route added.
You can also use the command set ip route default 172.16.1.1,
which will configure the route the same as the set ip route 0.0.0.0
172.16.1.1
will.
The 1900 switch default-gateway command was covered in Chapter 2.
Summary
I
n this chapter, we described inter-VLAN routing issues and solutions.
Because routers are needed to allow hosts on different networks to commu-
nicate, you also need to remember that a layer 3 device, either an external
router or an internal route processor, is needed to allow inter-VLAN com-
munication.
We discussed both internal route processors, known as Route Switch
Modules (RSMs), and external route processors and showed you how to use
them for inter-VLAN configuration.
