Chapter 21 Configuring L2VPN Interworking
Ethernet/VLAN to Frame Relay Interworking
FR DLCI to Ethernet VLAN 802.1Q
You can configure the FR DLCI to Ethernet VLAN 802.1Q feature on a router using the following steps:
1. config t
2. frame-relay switching
3. interface serial slot/subslot/port[:channel | .channel]
4. encapsulation frame-relay
5. frame-relay intf-type dce
6. frame-relay interface-dlci DLCI switched
7. interface [ fastethernet | gigabitethernet ] slot/subslot/port.subinterface
8. encapsulation dot1q VLAN-ID
9. connect connection-name [ fastethernet | gigabitethernet ] slot/subslot/port.subinterface serial
slot/subslot/port[:channel | .channel] interworking ethernet|ip
Note The order of the interfaces in the connect command is not important.
The following example shows how you can configure the FR DLCI to Ethernet VLAN 802.1Q feature
on a router using bridged interworking:
config t
frame-relay switching
interface serial 2/0/0:1
encapsulation frame-relay
frame-relay intf-type dce
frame-relay interface-dlci 100 switched
interface gigabitethernet 5/1/0.3
encapsulation dot1q 2
connect fr-vlan gigabitethernet 5/1/0.3 serial 2/0/0:1 100 interworking ethernet
AToM
Figure 21-9 illustrates different AToM configurations. This section explains the following AToM
configurations and provides examples:
• FR DLCI to Ethernet Port, page 21-24
• FR DLCI to Ethernet VLAN 802.1Q, page 21-26
FR DLCI to Ethernet Port
You can configure the FR DLCI to Ethernet port feature on a PE1 router using the following steps:
1. config t
2. mpls label protocol ldp
3. interface Loopback name
4. ip address local-ip-address local-mask
5. pseudowire-class name
6. encapsulation mpls
7. interworking ethernet|ip
