Hi,

I'm trying to set an IPv6 Address on an virtual interface veth0:
Here is the current config :

Code:

root@vxq:~# ip netn add net_ns0
root@vxq:~# ip netns exec net_ns0 ip link add veth0 type veth peer name veth1
root@vxq:~# ip netns exec tst_net_ns0 ifconfig veth0 inet6 add fd00::2/64

I get an error :

Code:

ifconfig: bad address 'inet6'

Can anyone tell me what is wrong with this address?

Can you try:

Code:

ip netns exec tst_net_ns0 ip addr add fd00::2/64 dev veth0

I tried it and it works.
In this case, In this case, I guess that ifconfig did not support 'inet6'.

Code:

root@vxq:~# ifconfig --help
BusyBox v1.24.1 (2018-09-06 07:51:52 IST) multi-call binary.

Usage: ifconfig [-a] interface [address]
