What is the maximum number of paths that AR series routers support to perform load balancing

0

The AR120&AR150&AR160&AR200&AR500&AR1200 series, AR2201-48FE, AR2202-48FE, AR2204-27GE, AR2204-27GE-P, AR2204-51GE-P, AR2204E, and AR2204 support a maximum of four paths. AR2220, AR2240, AR2240C, ,AR3600, and AR3200 series support a maximum of eight paths.

NOTE:
In V200R005C10 and later versions, devices with SRU200 or SRU400 installed support a maximum of 16 next hops for load balancing.
In V200R006 and later versions, devices with SRUX5 or SRU400 installed support a maximum of 16 next hops for load balancing.
In V200R007 and later versions, devices with SRU200E installed support a maximum of 16 next hops for load balancing.

How does the tunnel management module select tunnels in multi-path load balancing on S series switches
Q: How does the tunnel management module select tunnels in multi-path load balancing? If the number of tunnels for load balancing is set to 6 and eight LSP tunnels are available, how are tunnels selected during tunnel iteration? If a selected tunnel is in Down state, what will the tunnel management module select tunnels? If the selected tunnel becomes Up, what will the tunnel management module select tunnels? Q: TNLM randomly selects six tunnels and returns the tunnels to RM. If the state of a selected tunnel changes, for example, the Down state, TNLM selects one tunnel from the two alternate tunnels. If the selected tunnel becomes Up and the number of tunnels for load balancing is smaller than 6, TNLM selects another six tunnels for RM. Otherwise, the Up and Down states of a tunnel have no impact on load balancing.
