Run the display mpls l2vpn forwarding-info [ vc-label ] interface interface-type interface-
number command, and you can view that the ENTRYTYPE of the master PW is SEND,
PWSTATE is ACTIVE, BFDSTATE is UP, and ADMIN is UP. For example:
<Quidway> display mpls l2vpn forwarding-info interface vlanif 10
The Main PW Forward Information :
VCLABEL TNLTYPE ENTRYTYPE PWSTATE BFDSTATE ADMIN CTLWORD CC CV TNLID
------------------------------------------------------------------------------
23553 LSP SEND ACTIVE UP UP TRUE 1 8 0x10005
1 Record(s) Found.
The Second PW Forward Information :
VCLABEL TNLTYPE ENTRYTYPE PWSTATE BFDSTATE ADMIN CTLWORD CC CV TNLID
------------------------------------------------------------------------------
23553 LSP SEND ACTIVE UP UP TRUE 1 8 0x10003
1 Record(s) Found.
Run the manual-set pw-ac-fault command on the AC interface of the master PW, the following
situations occur:
l The status of the master PW is Down.
l VC status of the master PW is InActive, and that of the backup PW is Active.
l L2VPN data is switched to the backup PW.
Run the undo manual-set pw-ac-fault command on the AC interface of the master PW to rectify
the fault on the PW, the following situations occur:
l The status of the master PW is up.
l VC status of the master PW is Active, and VC status of the backup PW is InActive.
l L2VPN data is switched to the master PW.
6.11 Configuring Inter-AS PWE3
This section describes how to configure inter-AS PWE3. After inter-AS PWE3 is configured,
the MPLS backbone network that bears PWE3 can span multiple ASs.
6.11.1 Establishing the Configuration Task
Before configuring inter-AS PWE3, familiarize yourself with the applicable environment,
complete the pre-configuration tasks, and obtain the required data. This can help you complete
the configuration task quickly and accurately.
Applicable Environment
If the MPLS backbone network bearing PWE3 spans multiple ASs, the inter-AS PWE3 must be
configured.
Inter-AS PWE3 has the following schemes:
l Inter-AS PWE3-Option A: Option A is easy to implement and applicable to the scenario
where the number of inter-AS PWs is small.
l Inter-AS PWE3-Option C: In this option, PWs are not required for ASBRs. When multiple
inter-AS PWs exist in each AS, the ASBR may be the bottleneck in expanding the network.
S7700 does not support Option C.
