is not selected except in the case of load balancing or when the preceding tunnels are in the
Down state.
For example, if the tunnel select-seq lsp gre load-balance-number 1 command is configured,
a VPN selects GRE tunnels if no LSP exists. After an LSP is set up, the VPN selects the LSP
and does not use GRE tunnels anymore.
In IPv6 VPN networking, no GRE tunnel can be configured between PEs,and does not support
load balancing by tunnels, that is, the number of tunnels for load balancing is 1.
