Juniper JUNOSE 11.1.X - LINK LAYER CONFIGURATION 4-7-2010, Руководство по настройке

Страница: 216 / 774

■
9100—Specifies Ethertype value 0x9100, which is the default
■
Use an Ethertype value that matches the Ethertype value set on the customer
premises equipment (CPE) to which your router connects.
■
Example
host1(config-if)# svlan ethertype 8100
■
Use the no version to restore the default value, 9100.
■
See svlan ethertype.
svlan id
■
Use to assign S-VLAN IDs and VLAN IDs to VLAN subinterfaces.
■
Use S-VLAN ID and VLAN ID numbers that are in the range 0–4095 and that are
unique within the Ethernet interface.
■
Use the mac-address keyword to specify a unique MAC address for the VLAN
subinterface. When you do not specify a unique MAC address, the VLAN uses
the MAC address of the Ethernet interface.
■
Examples
host1(config-if)# svlan id 4 255
host1(config-if)# svlan id 4 255 mac-address 0090.1a01.1234
■
Issue the svlan id command before any upper bindings are made, such as IP or
PPPoE.
■
There is no no version.
■
See svlan id.
Configuring S-VLAN Tunnels for Layer 2 Services over MPLS
When you configure Ethernet layer 2 services over MPLS, you can create a special
type of S-VLAN called an S-VLAN tunnel that uses a single interface to tunnel traffic
from multiple VLANs across an MPLS network. The S-VLAN tunnel enables multiple
VLANs, each configured with a unique VLAN ID tag, to share a common S-VLAN ID
tag when they traverse an MPLS network.
Advantages
Using S-VLAN tunnels provides an easier and faster way to configure Ethernet layer
2 services over MPLS than using standard S-VLANs. For example, consider the network
configuration shown in Figure 19 on page 185.
