Solved how to add a ipv6 alias to jail by manual in freebsd14.2 ?

[fff2024g]

Dear all:
My pc is FreeBSD 14.2 with bastille tool for jail. I have created a vnet jail and want to manually add IPv6 ULA for my jail. Below is my configuration.

ifconfig_e0b_yggdrasil_name="vnet0"
ifconfig_vnet0=" syncDHCP "
ifconfig_vnet0_ipv6=" inet6 accept_rtadv "
ifconfig_vnet0_ipv6_alias0=" inet6 32f:dde0:cca9:7788::115/64 "

note: Now this jail can get SLAAC IPv6 address for vnet0
question: I want to add assigning other IPv6 address for jail. How to do that? Thanks.

problem was solved .
we can't not add space work in the address " xx.xx.xx.xx::x/64 "
error :
ifconfig_vnet0_ipv6_alias0=" inet6 32f:dde0:cca9:7788::115/64 "

correct:
ifconfig_vnet0_ipv6_alias0="inet6 32f:dde0:cca9:7788::115/64"

don't leave space work . thanks.
