Configuring the Circuit Emulation over Packet Shared Port Adapter
Command or Action
Step 6
Router(config-if-cem-xconn)# backup peer
peer-router-ip-addr vcid [pw-class
pw-class-name]
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
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:
OL-14127-17
xconnect 10.10.10.1 1 encap mpls
backup peer 10.10.10.2 200
Cisco ASR 1000 Series Aggregation Services Routers SIP and SPA Software Configuration Guide, Cisco IOS XE
Purpose
• 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
Note
router.
Configures a backup pseudowire link for failover mechanism if the link
between PE router and CE router fails or the remote PE router fails.
