'route add' fails on java meterpreter

[jcran]

running on ARM host, used a simple command to route a single host:

meterpreter > route add 192.168.10.1 255.255.255.0 1
Creating route 192.168.10.1/255.255.255.0 -> 1
[-] stdapi_net_config_add_route: Operation failed: 1

Getting this in the logs:

route in meterpreter is not the same as route at the msfconsole prompt.

Works as expected.
