Significance of "@" in "ip a" command

Question

The output of the ip a command in CentOs 7:

259: veth2060b59@if258: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue master docker0 state UP
    link/ether c6:1b:2a:b3:f6:c3 brd ff:ff:ff:ff:ff:ff link-netnsid 1
    inet6 fe80::c41b:2aff:feb3:f6c3/64 scope link
       valid_lft forever preferred_lft forever

Why there is "@" in the interface name?
What is the significance of it.?

Note:

Output of ifconfig command:

 veth2060b59: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet6 fe80::c41b:2aff:feb3:f6c3  prefixlen 64  scopeid 0x20<link>
        ether c6:1b:2a:b3:f6:c3  txqueuelen 0  (Ethernet)
        RX packets 1878  bytes 161872 (158.0 KiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 3262  bytes 372175 (363.4 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

there is no "@" in interface.

List of interfaces in /sys/class/net:
```
 [root@nix-lin415-01 net]# ls /sys/class/net/
 docker0  eno16777984  lo  veth2060b59
```
- note that interface name is veth2060b59 and NOT veth2060b95@if258.
