R2511-HP MSR Router Series MPLS Command Reference(V5)
105
Parameters
destination: Specifies the IP address of the peer PE.
vc-id: Specifies an ID for the VC, in the range of 1 to 4294967295.
control-word: Enables the control word function.
ethernet: Specifies the VC encapsulation type as Ethernet.
ip-interworking: Enables the SVC to support IP interworking. If you specify this keyword, when the PE
receives a packet from an AC bound to the SVC, it extracts the IP packet from the packet, sends the IP
packet to the peer PE over the SVC. When the PE receives a packet from the SVC, it encapsulates the IP
packet according to the link type of the AC bound to the SVC, and sends the encapsulated packet to the
AC link. In this way, the PEs at the two ends of a SVC shield the differences between two AC links,
implementing communication between the ACs with different link types.
no-control-word: Disables the control word function.
vlan: Specifies the VC encapsulation type as VLAN.
tunnel-policy tunnel-policy-name: Specifies a tunneling policy for the VC by its name, a string of 1 to 19
case-insensitive characters.
backup-peer ip-address vcid: Specifies the peer PE IP address and VC ID of the backup VC. The vc-id
argument specifies a VC ID for the backup VC, in the range of 1 to 4294967295.
backup-tunnel-policy tunnel-policy-name: Specifies a tunnel policy for the backup VC, a string of 1 to 19
case-insensitive characters.
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 primary static VC and a backup static VC on interface Serial 2/0 and enter static-L2VC view.
Specify the peer PE IP address and VC ID as 1.1.1.9 and 100 for the primary VC and as 2.2.2.9 and 200
for the backup VC.
