Chapter 21 Configuring Pseudowire
Configuring Hot Standby Pseudowire Support for ATM/IMA
DETAILED STEPS
Command Purpose
Step 1
enable
Example:
Router> enable
Enables privileged EXEC mode.
• Enter your password if prompted.
Step 2
configure terminal
Example:
Router# configure terminal
Enters global configuration mode.
Step 3
interface
interface-name
Example:
Router(config)# interface ATM0/IMA1
Selects the interface.
• interface-name—Name of the interface
Step 4
pvc
vpi/vci
l2transport
Example:
Router(config-if)# pvc 90/90
l2transport
Create or assigns a name to an ATM permanent virtual circuit (PVC), to
specify the encapsulation type on an ATM PVC.
• vpi—ATM network virtual path identifier (VPI) for this PVC.
• vci—ATM network virtual channel identifier (VCI) for this PVC.
Step 5
encapsulation { aal0 | aal5 }
Example:
Router(config-if)# encapsulation
aa10
Configures the ATM adaptation layer ( AAL) and encapsulation type for
an ATM virtual circuit (VC), VC class , VC, bundle, or permanent virtual
circuit (PVC) range.
Step 6
xconnect
peer-ip-address vc-id
encapsulation mpls
Example:
Router(config-if-srv)# xconnect
192.168.1.12 100 encapsulation mpls
Binds an attachment circuit to a pseudowire.
• peer-ip-address—IP address of the remote provider edge (PE) peer.
The remote router ID can be any IP address, as long as it is reachable.
• vcid—32-bit identifier of the VC between the routers at each end of
the layer control channel.
• encapsulation—Specifies the tunneling method to encapsulate the
data in the pseudowire.
Step 7
backup peer
peer-router-ip-addr
vcid
Example:
Router(config-if-xconn)# backup
peer 170.0.0.201 200
Specifies a redundant peer for a pseudowire virtual circuit (VC).
• peer-router-id—IP address of the remote peer router.
• vcid—32-bit identifier of the VC between the routers at each end of
the layer control channel.
