If set to "true" the sil-prio-reverse-for-deletes parameter for netconfd-pro

dictates that the SIL priority for DELETE operations will be reversed.
This parameter can be used to delete leafref nodes with referenced by node in reverse order.
If 'false' then the SIL priority will not be reversed.

The default is "false". 


The sil-prio-reverse-for-deletes parameter can be set via the command line when starting netconfd-pro:


user@system> netconfd-pro --sil-prio-reverse-for-deletes=true


or configured in the /etc/yumapro/netconfd-pro.conf file:


#### sil-prio-reverse-for-deletes
#
# If set to "true" this parameter for netconfd-pro
# dictates that the SIL priority for DELETE operations will be reversed.
# This parameter can be used to delete leafref nodes with referenced
# by node in reverse order.
# If 'false' then the SIL priority will not be reversed.
#
 sil-prio-reverse-for-deletes false
