Chapter 21 Configuring L2VPN Interworking
Ethernet/VLAN to ATM AAL5 Interworking
You can configure the ATM AAL5 to Ethernet VLAN 802.1Q feature on a PE2 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
8. interface [ fastethernet | gigabitethernet ] slot/subslot/port.subinterface
9. encapsulation dot1q VLAN-ID
10. xconnect remote-ip-address vci pw-class name
Note In the case of ATM AAl5 to VLAN, the PE2 configuration includes the interworking command
for both bridged and routed interworking.
The following example shows how to configure the ATM AAL5 to Ethernet VLAN 802.1Q feature on a
PE1 router using bridged interworking:
config t
mpls label protocol ldp
interface Loopback100
ip address 10.0.0.100 255.255.255.255
pseudowire-class atm-vlan
encapsulation mpls
interworking ethernet
interface atm 2/0/0
pvc 0/200 l2transport
encapsulation aal5snap
xconnect 10.0.0.200 140 pw-class atm-vlan
The following example shows how to configure the ATM AAL5 to Ethernet VLAN 802.1Q feature on a
PE2 router using bridged interworking:
config t
mpls label protocol ldp
interface Loopback200
ip address 10.0.0.200 255.255.255.255
pseudowire-class atm-vlan
encapsulation mpls
interworking ethernet
interface gigabitethernet 5/1/0.3
encapsulation dot1q 1525
xconnect 10.0.0.100 140 pw-class atm-vlan
