l Configuring tunnels between PEs based on the tunnel policy
l Configuring the IP address for the CE interface that is connected to the PE
Data Preparation
To configure basic BGP/MPLS IP VPN, you need the following data.
No. Data
1 To configure a VPN instance, you need the following data:
l Name of the VPN instance
l (Optional) Description of the VPN instance
l RD, VPN target attribute of the VPN instance
l (Optional) Routing policy used to control the sending and receiving of VPN routes
l (Optional) Tunnel policy
l (Optional) Maximum number of routes permitted in a VPN instance
2
IP address of the PE interface that is connected to the CE
3 Route-exchanging mode between the PE and CE, which can be the static route, RIP,
OSPF, IS-IS, or BGP
4 AS number of the PE
5 IP address and interface of the PE used to establish the BGP peer relationship
3.4.2 Configuring a VPN Instance
This part describes how to configure a VPN instance to manage VPN routes.
Context
For the details, see Configuring VPN Instances.
3.4.3 Binding an Interface with a VPN Instance
After associating an interface with a VPN instance, you can change the interface to a VPN
interface. As a result, packets that pass through the interface are forwarded according to the
forwarding information of the VPN instance, and Layer 3 attributes such as the IP address and
routing protocol that are configured for the interface, are deleted. These Layer 3 attributes need
to be re-configured if required.
Context
Do as follows on the PE that is connected to the CE.
