R2511-HP MSR Router Series MPLS Command Reference(V5)

101
revertive: Enables support for switchback. With this keyword specified, when the primary VC recovers,
traffic is switched from the backup VC back to the primary VC automatically. If you do not specify this
keyword, traffic will not be switched back automatically.
wtr-time wtr-time: Specifies the switchback delay time. When the primary VC recovers, the device waits
for the switchback delay time before switching the traffic from the backup VC back to the primary VC. The
value range for the wtr-time argument is 1 to 720, and the default is 30, in minutes.
Usage guidelines
If you do not specify a tunneling policy, or if you specify a nonexistent tunneling policy, the default policy
is used for the VC. The default tunneling policy selects only one tunnel in this order: LSP tunnel, GRE
tunnel, CR-LSP tunnel. For information about how to configure a tunneling policy, see MPLS Configuration
Guide.
Only L2VPNs that use encapsulation types of PPP, HDLC, FR DLCI, FR port mode, ATM AAL5 transparent
transport, and ATM cell transparent transport support the control word function.
If the AC link type is Ethernet, the VC encapsulation type can be Ethernet or VLAN. The device allows you
to specify the VC encapsulation type for only Layer 3 Ethernet interfaces and subinterfaces, Layer 3
virtual Ethernet interfaces and subinterfaces, VLAN interfaces, and VE-L2VPN-Terminate interfaces.
When not specified, the VC encapsulation type is Ethernet on Layer 3 Ethernet interfaces, Layer 3 virtual
Ethernet interfaces, and VE-L2VPN-Terminate interfaces and is VLAN on Layer 3 Ethernet subinterfaces,
Layer 3 virtual Ethernet subinterfaces, and VLAN interfaces.
Examples
# Create a Martini VC, and specify the peer PE IP address as 2.2.2.9 and VC ID as 999.
<Sysname> system-view
[Sysname] interface serial 2/0
[Sysname-Serial2/0] mpls l2vc 2.2.2.9 999
Related commands
tunnel-policy
mpls l2vc switchover
Use mpls l2vc switchover to switch traffic from the active VC to the standby VC manually.

Default command level
2: System level
Usage guidelines
This command applies only to Martini VCs create by using the mpls l2vc command.
You can use this command to manage traffic on the network.
After you execute this command, if the VC has an available primary or backup VC, the device switches
traffic from the VC to the primary or backup VC. Otherwise, the device does not switch traffic.
