This value sets a numeric load-balancing parameter, likely the number of tunnels or paths to spread traffic across, for this tunnel policy, ranging from 1 to 64 and defaulting to 1, meaning no load sharing. Administrators increase it when they want traffic under this policy to be spread across multiple parallel tunnels rather than a single path. For example, setting this to 4 would configure the policy to load-balance traffic across up to four tunnels simultaneously.
