L2VPN
Configure the VPN-target of
the MPLS L2VPN
Configure the Layer 2 MTU

Range of an existing CE
Enter an existing CE
Create connections between
CEs
CAUTION:
You can only change the CE range to a number larger than the existing one.
■
For example, you can change a CE range from 10 to 20, rather than from 10 to
5. The only way to change a CE range to a smaller number is to remove the CE
and create a new one.
You can configure only one VLAN on the access side of each VPN private
■
network. Each VLAN can have only one interface. And all the VLANs
connecting to the interface must have IGMP disabled.
In Kompella MPLS L2VPN, the encapsulation type on the access side of each
■
private network can be Ethernet access and VLAN access. Ethernet access is the
default type. If you configure the encapsulation type as Ethernet access, the
port link type in a private network VLAN is Access type; if you configure the
encapsulation type as VLAN access, the port link type in a private network

Description
Required. For an MPLS L2VPN,
you must configure the RD
before performing other
configurations. An RD cannot
be modified once it is
configured. The only way to
modify a configured RD is to
remove the corresponding
MPLS L2VPN and create
another one. As for L2VPN, it
is recommended that you
assign a unique RD for each
VPN.
Required
Optional. The same MTU
value must be configured for
all PEs in the same VPN.
Required. Each CE created on
a PE needs to uniquely
correspond to one actual CE
device connected to the PE.
You need to specify a unique
ID for these CEs. You can also
specify the CE Range. It is
desired that the CE ID begins
with 1 and increases in step of
1.
Required. When planning a
VPN, you can specify CE IDs
for CEs beginning with 1 and
increasing in step of 1, and
then establish connections by
CE IDs. You can establish
connections with CE Offset
not provided for simplifying
the configuration. In this case,
the default CE Offset is used.
