T-PE1

The following shows an example of the T-PE1 configuration:

*A:ALA-T-PE1>config>service>epipe# info
----------------------------------------------
            endpoint "x" create
            exit
            endpoint "y" create
            exit
            spoke-sdp 1:100 endpoint "y" create
                precedence primary
                revert-time 0
            exit
            spoke-sdp 4:400 endpoint "y" create
                precedence 0
            exit
            no shutdown
----------------------------------------------
*A:ALA-T-PE1>config>service>epipe#

The following shows an example of the T-PE2 configuration for 7950 XRS.

            endpoint "x" create
            exit
            endpoint "y" create
            exit
            sap endpoint "x" create
            exit
            spoke-sdp 3:300 endpoint "y" create

                precedence 0
            exit
            no shutdown
----------------------------------------------
*A:ALA-T-PE2>config>service>epipe#

The following shows and example of the T-PE2 configuration for 7450 ESS and 7750 SR.

T-PE2

*A:ALA-T-PE2>config>service>epipe# info
----------------------------------------------
            endpoint "x" create
            exit
            endpoint "y" create
            exit
            sap 2/2/2:200 endpoint "x" create
            exit
            spoke-sdp 3:300 endpoint "y" create
                precedence primary
                revert-time 0
            exit
            spoke-sdp 6:600 endpoint "y" create
                precedence 0
            exit
            no shutdown
----------------------------------------------
*A:ALA-T-PE2>config>service>epipe#

S-PE1

Specifying the vc-switching parameter enables a VC cross-connect, so the service manager does not signal the VC label mapping immediately, but puts this into passive mode.

The following example shows the configuration:

*A:ALA-S-PE1>config>service>epipe# info
----------------------------------------------
...
            spoke-sdp 2:200 create
            exit
            spoke-sdp 3:300 create
            exit
            no shutdown
----------------------------------------------
*A:ALA-S-PE1>config>service>epipe#

S-PE2

Specifying the vc-switching parameter enables a VC cross-connect, so the service manager does not signal the VC label mapping immediately, but puts this into passive mode.

The following example shows the configuration:

*A:ALA-S-PE2>config>service>epipe# info
----------------------------------------------
...
            spoke-sdp 2:200 create
            exit
            spoke-sdp 3:300 create
            exit
            no shutdown
