Caution:
Following must be met to make an LDP Layer 2 VPN to go up:
The interfaces of the two CEs are physically up.
Two LSP tunnels, which are opposite in direction, exist between two PEs.
The encapsulation types of interfaces of the two CEs are the same and are
supported by the MPLS VLL.
It is recommended that the VLANs on PE A and PE B which are connected to the
CEs be consistent.
LDP remote sessions exist between PEs and are in Operational state.
To establish a tunnel, routes to the peer PE are necessary. So you need to
configure interior gateway protocol (IGP) on each router along the path, such as
OSPF.

1.3.3 Martini MPLS VLL Primary/backup PW Configuration Example

I. Network requirements
The CEs are connected through VLAN. A remote connection is established
between PE2 and PE1, PE2 and PE3, respectively.
On VLAN101, the virtual interface of PE2, configure a primary virtual connection to
PE1 and a backup virtual connection to PE3. Enable manual primary/backup
switchover on VLAN101.
In system view, restore the connection mode to primary.
