How to Configure Layer 2 Tunnel Protocol Version 3
49
Cisco IOS Releases 12.0(29)S and 12.2(25)S
Step 3
interface type slot/port
Example:
Router(config)# interface ATM
4/1
Specifies the interface by type, slot, and port number, and enters interface
configuration mode.
Step 4
atm mcpt-timers
[timeout-value-1
timeout-value-2
timeout-value-3]
Example:
Router(config-if)# atm
mcpt-timers 10 100 1000
(Optional) Sets up the cell-packing timers, which specify how long the PE
router can wait for cells to be packed into an L2TPv3 packet.
Step 5
pvc [name] vpi/vci [ces | ilmi
| qsaal | smds | l2transport]
Example:
Router(config-if)# pvc 1/32
l2transport
Creates or assigns a name to an ATM PVC, specifies the encapsulation type on
an ATM PVC, and enters ATM VC configuration mode.
Step 6
encapsulation aal0
Example:
Router(config-if-atm-vc)#
encapsulation aal0
Specifies ATM AAL0 encapsulation for the PVC.
Step 7
cell-packing [cells]
[mcpt-timer timer]
Example:
Router(config-if-atm-vc)#
cell-packing 10 mcpt-timer 2
Enables the packing of multiple ATM cells into each L2TPv3 data packet.
• cells—(Optional) The number of cells to be packed into an L2TPv3 data
packet. The default number of ATM cells to be packed is the MTU of the
interface divided by 52.
• mcpt-timer timer—(Optional) Specifies which timer to use. The mcpt
timers are set using the mcpt-timers command. The default value is 1.
Step 8
xconnect peer-ip-address vcid
pseudowire-parameters
[sequencing {transmit | receive
| both}]
Example:
Router(config-if-atm-vc)#
xconnect 10.0.3.201 888
encapsulation l2tpv3
Binds an attachment circuit to a Layer 2 pseudowire and enters Xconnect
configuration mode.
