Purpose
Command or Action
•
encapsulation mpls
sets MPLS for tunneling mode.
•
pw-class name
specifies a pseudowire class that includes the
encapsulation mpls
command.
The
peer-router-id
and
vcid
combination must be unique on the
router.
Note
Configures a backup pseudowire link for failover mechanism if the link
between PE router and CE router fails or the remote PE router fails.

Step 6
Example
The following example shows pseudowire redundancy configured for a CEM circuit (group). In the following
example, the
xconnect
command configures a primary pseudowire for CEM group 0. The
backup peer
command creates a redundant pseudowire for a CEM circuit (group).
int cem0/1/0
no ip address
cem 0
xconnect 10.10.10.1 1 encap mpls
backup peer 10.10.10.2 200
exit
Configuring T1 on a 24-Port Channelized T1/E1 ATM CEoP SPA
When configuring T1 on a 24-Port Channelized T1/E1 ATM CEoP SPA, follow these guidelines:
•
There can be 0 to 23 channels under a T1 controller, one for each T1 time slot.
•
Each channel can be configured as a CEM group.
•
Maximum channels under a single CEM group are 24.
•
Each CEM group number under a controller must be unique.
•
A maximum of 191 CEM circuits can be configured.
To configure T1 on a 24-Port Channelized T1/E1 ATM CEoP SPA, perform the following steps:
