•
If the matching tunnel is unavailable (for example, the tunnel is down or the tunnel's ACL does
not permit the traffic) and is not specified with the disable-fallback keyword, the local PE
continues to match other tunnels. If the tunnel is specified with the disable-fallback keyword,
the local PE stops matching and tunnel selection fails.
To configure a tunneling policy for a VPN instance:
Step
1. Enter system view.
2. Create a tunneling policy
and enter tunneling policy
view.
3. Configure a preferred
tunnel and specify a tunnel
interface for it.
4. Specify the tunnel selection
preference order and the
number of tunnels for load
balancing.
5. Return to system view.
6. Enter VPN instance view.
7. Enter IPv6 VPN view.

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.
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.
