Command Remarks
1. Enter system view.
system-view N/A
2. Create a tunneling policy
and enter tunneling policy
view.
tunnel-policy tunnel-policy-name
N/A
3. Configure a preferred tunnel
and specify a tunnel
interface for it.
preferred-path number interface
tunnel tunnel-number
[ disable-fallback ]
Optional.
By default, no preferred tunnel is
configured.
In a tunneling policy, you can
configure up to 64 preferred tunnels.
The tunnel interfaces specified for the
preferred tunnels can have the same
destination address and the tunnel
encapsulation type must be MPLS TE.
4. Specify the tunnel selection
preference order and the
number of tunnels for load
balancing.
tunnel select-seq { cr-lsp | gre |
lsp } * load-balance-number
number
Optional.
By default, only one tunnel is selected
(no load balancing) in this order: LSP
tunnel, GRE tunnel, CR-LSP tunnel.
NOTE:
• 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
only when no LSP exists. After an
LSP is created, the VPN uses the LSP
tunnel instead.
• 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
balancing, tunnels of different types
may be used.
5. Return to system view.
quit N/A
6. Enter VPN instance view.
ip vpn-instance
vpn-instance-name
N/A
7. Enter IPv6 VPN view.
ipv6-family Optional.
8. Apply the tunneling policy to
the VPN instance.
tnl-policy tunnel-policy-name
By default, only one tunnel is selected
(no load balancing) in this order: LSP
tunnel, GRE tunnel, CR-LSP tunnel.
The tunneling policy to be applied must
have existed. Otherwise, the default
tunneling policy is used. The default
tunneling policy selects only one tunnel
in this order: LSP tunnel, GRE tunnel,
CR-LSP tunnel.
