Configuring VPN
Follow these steps to configure VPN:
To do...
Enter system view
Create a VPN and enter
MPLS L2VPN view
Configure an RD for the
L2VPN
Associate a particular VPN
with one or more VPN
targets
Set the Layer 2 MTU for
the VPN
The command for creating a VPN and entering MPLS L2VPN view is also available
in MPLS L2VPN view.
CAUTION:
The mtu command is not recommended. It affects only parameter negotiation,
■
which may occur; it does not affect data forwarding.
With Kompella MPLS L2VPN, you must create on the PE an L2VPN instance for
■
each VPN where a directly connected CE resides. When creating an L2VPN, you
must specify an encapsulation type matching that of the CE interface.
The configuration of the VPN targets and RD are the same as that for MPLS
■
L3VPN. For Kompella MPLS L2VPN, the RD is required. Once configured, an RD
cannot be changed, unless you delete the L2VPN and then re-create it.
Use the command...
system-view
bgp as-number
peer { group-name | ip-address }
as-number as-number
peer { group-name | ip-address }
connect-interface interface-type
