To do… Use the command… Remarks
Apply an export routing policy
to the current VPN instance export route-policy
route-policy
Optional
By default, all VPN instance
routes permitted by the export
target attribute can be
redistributed.
z
A single vpn-target command can configure up to eight VPN targets. You can configure up to 20
VPN targets for a VPN instance.
z
You can define the maximum number of routes for a VPN instance to support, preventing too many
routes from being redistributed into the PE.
z
Before associating a routing policy with a VPN instance, you must create the routing policy at first.
Otherwise, the default routing policy is used.
Configuring a Tunneling Policy of a VPN Instance
Configuring a tunneling policy
Follow these steps to configure a tunneling policy:
To do… Use the command… Remarks
Enter system view system-view —
Create a tunneling policy and
enter tunneling policy view tunnel-policy
tunnel-policy-name
Required
Specify the priorities of tunnels
and the number of tunnels for
load balancing tunnel select-seq { cr-lsp |
lsp } * load-balance-number
number
Required
By default, the LSP tunnel is
used and the number of tunnels
for load balancing is 1.
z
When you configure tunnel priorities using the tunnel select-seq command, a tunnel type closer to
the select-seq keyword has a higher priority. For example, with the tunnel select-seq lsp gre
load-balance-number 1 command configured, VPN uses a GRE tunnel if no LSP exists. Once an
LSP is created, the LSP tunnel is used instead.
z
If you specify more than one tunnel type and the number of tunnels of a type is less than the
specified number of tunnels for load balance, tunnels of different types may be used.
