Forcing A Manual Switchover To The Backup Pseudowire; Configuring Preferred Tunnel Path - Cisco ASR 9000 Series Configuration Manuallines

Implementing Point to Point Layer 2 Services
• Use the neighbor keyword to specify the peer to the cross-connect. The A.B.C.D argument is the IPv4 address
of the peer.
• Use the pw-id keyword to configure the pseudowire ID. The range is from 1 to 4294967295.
Step 11 Use the commit or end command.
commit - Saves the configuration changes and remains within the configuration session.
end - Prompts user to take one of these actions:
• Yes - Saves configuration changes and exits the configuration session.
• No - Exits the configuration session without committing the configuration changes.
• Cancel - Remains in the configuration mode, without committing the configuration changes.

Forcing a Manual Switchover to the Backup Pseudowire

To force the router to switch over to the backup or primary pseudowire, use the l2vpn switchover command
in EXEC mode.
A manual switchover is made only if the peer specified in the command is actually available and the
cross-connect moves to the fully active state when the command is entered.

Configuring Preferred Tunnel Path

This procedure describes how to configure a preferred tunnel path.
Note The tunnel used for the preferred path configuration is an MPLS Traffic Engineering (MPLS-TE) tunnel.
SUMMARY STEPS
1. configure
2. l2vpn
3. pw-class {name}
4. encapsulation mpls
5. preferred-path {interface} {tunnel-ip value | tunnel-te value | tunnel-tp value} [fallback disable]
6. Use the commit or end command.
