I cannot bind more than 8 destination UseNetworks to vCore.

Please be advised the maximum number of destination UserNetwork that can be configured on portal is '13', but the maximum number of destination UserNetwork that can be binded to vCore at a time is '8'.
* If you try to register more than 13, an error message "more than table limit" appears.

*According to the situation, the number of destination UserNetwork can be reduced by changing the destination UserNetworks to network address.
<Example>
Host A(192.168.0.1/32)
Host B(192.168.0.2/32)
If these two are registered, they can be integrated into one destination UserNetwork
such as Network A(192.168.0.0/17)

The number of destination UserNetwork is limited, so please refer to FAQ below, too.
