Fault analysis
The VC ID is optional for the static PWE3. The static PW without a VC ID cannot be switched
with the dynamic PW.
If you configure the mixed PW switching, specify a non-zero VC ID for the static PW.
Otherwise, the multihop PW (MH-PW) cannot be located. Normally, the VC ID for the static
PW is the same as that of the dynamic PW.
In this case, the possible cause is that the PW ID of the static PW is 0. You can use the following
method to solve it.
# Configure U-PE1:
[U-PE1] pw-template pwt1
[U-PE1] peer-address 3.3.3.3
[U-PE1-Pos1/0/0] mpls static-l2vc pw-template pwt1 1 transmit-vpn-label 100
receive-vpn-label 100
# Configure U-PE2:
[U-PE1] pw-template pwt1
[U-PE1] peer-address 1.1.1.1
[U-PE1-Pos1/0/0] mpls static-l2vc pw-template pwt1 1 transmit-vpn-label 100
receive-vpn-label 100
# Configure static PW switching on S-PE:
[S-PE] mpls switch-l2vc 3.3.3.3 100 trans 100 recv 100 between 1.1.1.1 100 trans 100
recv 100 encapsulation ppp
Establishment of the static PW does not involve the signaling. As long as the label is correct,
VC IDs can be different.
Troubleshooting procedure
Step 1 Create a PW template in the system view.
Step 2 Specify a peer for the PW in the PW template.
Step 3 Create a PW by using the PW template and specify a non-zero PW ID (also called VC ID) for it.
Or specify a non-zero VC ID for the static PW.
—End
Summary
The PW ID for the static PW is optional.
Static PWs to be switched must be configured with a PW ID.
