4.5.2 Creating and Configuring VPN

I. Creating VPN
For BGP MPLS L2VPN, you must create a VPN view of MPLS L2VPN on a PE and
specify its encapsulation type, which must be consistent with that for the CE interface.
Perform the following configurations in system view.
Table 4-14 Create VPN
Create a VPN and specify its
encapsulation type
Enter the MPLS L2VPN view
Delete the MPLS L2VPN view
II. Configuring VPN
Configure VPN-target and RD in the VPN view of MPLS L2VPN, which are identical
with those of BGP/MPLS VPN will not be detailed here. But it should be noted that you
must first configure RD for an MPLS L2VPN before other commands and you cannot
modify the RD once you have configured it. The only way out is to delete the MPLS
L2VPN and create another.
You can also configure L2 MTU for the VPN, which must be globally consistent. If the
MTU values for the same VPN on two PEs are different, then the two PEs cannot
exchange reachable information and no links can be established between them.
