Associating a VPN instance with an interface
After creating and configuring a VPN instance, associate the VPN instance with the MCE's interface
connected to the site and the interface connected to the PE.
To associate a VPN instance with an interface:
Step Command Remarks
1. Enter system view.
system-view
N/A
2. Enter interface view.
interface
interface-type
interface-number
N/A
3. Associate a VPN instance
with the interface.
ip binding vpn-instance
vpn-instance-name
By default, an interface is not
associated with a VPN instance.
The
ip binding vpn-instance
command deletes the IP address
of the current interface. You must
re-configure an IP address for the
interface after configuring the
command.
Configuring route related attributes for a VPN instance
Step Command Remarks
1. Enter system view.
system-view
N/A
2. Enter VPN instance
view or IPv4 VPN view.
• Enter VPN instance view:
ip vpn-instance
vpn-instance-name
• Enter IPv4 VPN view:
a. ip vpn-instance
vpn-instance-name
b. address-family ipv4
Configurations made in VPN
instance view apply to both IPv4
VPN and IPv6 VPN.
IPv4 VPN prefers the
configurations in IPv4 VPN view
over the configurations in VPN
instance view.
3. Configure route targets.
vpn-target
vpn-target&<1-8> [
both
|
export-extcommunity
|
import-extcommunity
]
By default, no route targets are
configured.
4. Set the maximum
number of active routes
allowed.
routing-table
limit
number
{ warn-threshold |
simply-alert
}
By default, the maximum number
of active routes in the VPN
instance is not limited.
Setting the maximum number of
active routes for a VPN instance
can prevent the PE from learning
too many routes.
