to-tunnel
Provides for the configuration of a to-tunnel for a PVC tunnel connection.
Syntax: to-tunnel ttName [backup bttName]
no to-tunnel
ttname
Specify the name of the pre-configured to-tunnel for this PVC tunnel connection.
bttName
Specify the name of the to-tunnel backup for this to-tunnel.
Description: The PVC tunnel connection is configured by associating pre-configured uni-directional to and from tunnels at each end of the CCC connection service. Each to-tunnel primary and backup is configured for no-traffic. The from-tunnel specified is the same as the to-tunnel at the other end of the CCC connection service. Each to-tunnel can have a single optional backup tunnel associated with it. Each from-tunnel can have up to two optional backup tunnels associated with it. The PVC tunnel connection at each end of the CCC connection service is created by specifying the interface and DLCI associated with the PVC for this end of the connection, the name of the to-tunnel, from-tunnel and any backups.
Use the connection name pvc-tunnel command to enter connection configuration mode for the configuration of a PVC tunnel connection. Once in connection configuration mode a to-tunnel can be associated with this PVC tunnel connection using the to-tunnel command.
Use the connection name tunnel-stitch command to enter connection configuration mode for the configuration of a tunnel-stitch connection. Once in connection configuration mode, use the from-tunnel command to configure the tunnel that has its egress at this midpoint stitch node. Use the to-tunnel command to configure the tunnel that has its ingress at this midpoint stitch node.
Use the no to-tunnel command to delete this to-tunnel from the stitch. Perform a shutdown of the connection before attempting to delete a tunnel from a connection.
Modify the from-tunnel of a connection by performing a shutdown of the connection, deleting the tunnel, entering a new from-tunnel and performing a no shutdown of the connection.
Factory Default: None.
Command Mode: Connection Configuration.
Example 1: The following example provides a complete CCC service connection configuration for the 1/1/1.21 frame relay PVC interface side of the CCC service connection by:
- Configuring the 1/1/1 interface for frame-relay encapsulation.
- Creating the 1/1/1.21 PVC.
- Creating the PVC tunnel connection specifying Bos21 as the to-tunnel and Chi23 as the from tunnel.
router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)#interface pos 1/1/1
router(config-if)#encapsulation frame-relay
router(config-if)#no shutdown
router(config-if)#exit
router(config)#interface frl-pvc 1/1/1.21
router(config-pvc)#encapsulation frl-ccc
router(config-pvc)#description Bos-Doc DLCI 21 to 23 CCC connection
router(config-pvc)#no shutdown
router(config-pvc)#exit
router(config)#connection BosCCC pvc-tunnel interface frl-pvc 1/1/1.21
router(config-cxn)#to-tunnel Bos21 backup BkBos21
router(config-cxn)#from-tunnel Chi23 backup BkChi23a BkChi23b
router(config-cxn)#no shutdown
router(config-cxn)#end
router#
Example 2: The following example modifies the BosCCC PVC tunnel connection by first deleting the Bos21 to-tunnel and its backup and replaces it with the Bos21a primary and BkBos21a backup tunnels:
- Configuring the 1/1/1 interface for frame-relay encapsulation.
- Creating the 1/1/1.21 PVC.
- Creating the PVC tunnel connection specifying Bos21 as the to-tunnel and Chi23 as the from tunnel.
router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)#connection BosCCC pvc-tunnel interface frl-pvc 1/1/1.21
router(config-cxn)#shutdown
router(config-cxn)#no to-tunnel Bos21 backup BkBos21
router(config-cxn)#to-tunnel Bos21a backup BkBos21a
router(config-cxn)#no shutdown
router(config-cxn)#end
router#
