Layer 3
The AT-8800 Series Switch routes IP and IP multicasting traffic at wire speed
between VLANs, and supports a number of other Layer 3 protocols. Once a
VLAN has been created (see “Virtual Local Area Networks (VLANs)” on page 72),
the VLAN name can be used wherever a logical interface is required in
commands for configuring routing protocols.
VLAN names are of the form:
VLAN-vlanname
or
VLANn
where vlanname is the manager-assigned name of the VLAN, and n is the
VLAN identifier (VID).
For example, to create a VLAN called “admin” with a VID of 11, and add port 3
to it, use the commands:
CREATE VLAN=admin VID=11
ADD VLAN=11 PORT=3
The following names can be used to identify this VLAN in routing commands:
vlan-admin
vlan11
The following sections illustrate the use of VLANs for IP, RIP, IPX, AppleTalk
and RSVP. For a complete description of all the protocols supported by the
switch, see the Rapier Switch Software Reference.
