I added two namespace:

ip netns add ns-0
ip netns add ns-1
root@debian:~# ip netns show 
cni-19d9438b-3df3-bf3d-a1e8-b4f00d2248b5 (id: 1)
cni-7c21b40c-3188-dc56-19da-a5897af1e916 (id: 0)
ns-1
ns-0

I have the following interfaces:

I have two outputs:

root@debian:~# ip netns exec ns-0 ip addr
1: lo: <LOOPBACK> mtu 65536 qdisc noop state DOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
root@debian:~# ip netns exec ns-1 ip addr
1: lo: <LOOPBACK> mtu 65536 qdisc noop state DOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

My /etc/cni/net.d/10-mynet.conf is:

{
	"cniVersion": "0.2.0",
	"name": "mynet",
	"type": "bridge",
	"bridge": "cni0",
	"isGateway": true,
	"ipMasq": true,
	"ipam": {
		"type": "host-local",
		"subnet": "192.168.1.0/24",
		"routes": [
			{ "dst": "0.0.0.0/0" }
		]
	}
}

My /etc/cni/net.d/99-loopback.conf is:

{
	"cniVersion": "0.2.0",
	"name": "lo",
	"type": "loopback"
}

Then I wanted to create two peered vet such as:

root@debian:~# ip link add dev vetha9a94b4a@if2 type veth peer vetheea973b5@if2
Error: Attribute failed policy validation

After googling I found my interfaces not longer than 15. How can I‌ changed my interfaces name without any change in their attributes?
