Chapter 21 Configuring Pseudowire
Configuring Hot Standby Pseudowire Support for ATM/IMA
Verifying Hot Standby Pseudowire Support for ATM/IMA
To verify the configuration of Hot Standby Pseudowire Support for ATM/IMA, use the show commands
as shown in the following examples.
Router# show mpls l2transport vc 90
Local intf Local circuit Dest address VC ID Status
------------- -------------------------- --------------- ---------- ----------
AT0/IMA1 ATM VPC CELL 90 2.2.2.2 90 STANDBY
AT0/IMA1 ATM VPC CELL 90 180.0.0.201 90 UP
Router# show mpls l2transport vc detail
ASR901-PE2#sh mpls l2 vc 90 deta
Local interface: AT0/IMA1 up, line protocol up, ATM VPC CELL 90 up
Destination address: 2.2.2.2, VC ID: 90, VC status: standby
Output interface: Vl500, imposed label stack {22 17}
Preferred path: not configured
Default path: active
Next hop: 150.1.1.201
Create time: 5d02h, last status change time: 2d17h
Last label FSM state change time: 5d02h
Signaling protocol: LDP, peer 2.2.2.2:0 up
Targeted Hello: 170.0.0.201(LDP Id) -> 2.2.2.2, LDP is UP
Graceful restart: not configured and not enabled
Non stop routing: not configured and not enabled
Status TLV support (local/remote) : enabled/supported
LDP route watch : enabled
Label/status state machine : established, LrdRru
Last local dataplane status rcvd: No fault
Last BFD dataplane status rcvd: Not sent
Last BFD peer monitor status rcvd: No fault
Last local AC circuit status rcvd: DOWN(standby)
Last local AC circuit status sent: No fault
Last local PW i/f circ status rcvd: No fault
Last local LDP TLV status sent: DOWN(standby)

Step 4
xconnect
peer-ip-address vc-id
encapsulation mpls
Example:
Router(config-if)# xconnect
192.168.1.12 100 encapsulation mpls
Binds an attachment circuit to a pseudowire, and to configure an Any
Transport over MPLS (AToM) static 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 5
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-ip-addr—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.
