Configuring the Xconnect Attachment Circuit for ATM AAL5 SDU Mode over
L2TPv3 Example
The following configuration binds a PVC to an Xconnect attachment circuit to forward ATM cells over
an established L2TPv3 pseudowire:
pw-class atm-xconnect
encapsulation l2tpv3
interface ATM 4/1
pvc 5/500 l2transport
encapsulation aal5
xconnect 10.0.3.201 888 pw-class atm-xconnect
Configuring OAM Local Emulation for ATM AAL5 over L2TPv3 Example
The following configuration binds a PVC to an Xconnect attachment circuit to forward ATM AAL5
frames over an established L2TPv3 pseudowire, enables OAM local emulation, and specifies that AIS
cells will be sent every 30 seconds:
pw-class atm-xconnect
encapsulation l2tpv3
interface ATM 4/1
pvc 5/500 l2transport
encapsulation aal5
xconnect 10.0.3.201 888 pw-class atm-xconnect
oam-ac emulation-enable 30
Configuring Protocol Demultiplexing for L2TPv3 Examples
The following examples show how to configure the Protocol Demultiplexing feature on the IPv4 PE
routers. The PE routers facing the IPv6 network do not require demultiplexing configuration.
Ethernet Interface
interface ethernet 0/1
ip address 172.16.128.4
