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
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 IPv4 VPN view.
ipv4-family
Optional.
8. Apply the tunnel 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.
NOTE:
• A tunneling policy configured in VPN instance view is applicable to both IPv4 VPNs and IPv6 VPNs.
• You can configure a tunneling policy for IPv4 VPNs in both VPN instance view and IPv4 VPN view. A
tunneling policy configured in IPv4 VPN view takes precedence.
Configuring an LDP instance
LDP instances are for carrier's carrier network applications.
This task is to configure the LDP capability for an existing VPN instance, create an LDP instance for the
VPN instance, and configure LDP parameters for the LDP instance.
