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:

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.
