SDN interface creation

[damo2929]

hi all

just looking for information about the SDN and the interfaces it creates.

I have created a vlan SDN on bond0 but its created 4 interfaces instead of the expected 2

13: ln_example@pr_example: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue master example state UP mode DEFAULT group default qlen 1000
    link/ether e6:ec:d2:7b:98:75 brd ff:ff:ff:ff:ff:ff
14: pr_example@ln_example: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue master bond0v77 state UP mode DEFAULT group default qlen 1000
    link/ether 5a:eb:55:6b:8a:e5 brd ff:ff:ff:ff:ff:ff
15: bond0v77: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DEFAULT group default qlen 1000
    link/ether 5a:eb:55:6b:8a:e5 brd ff:ff:ff:ff:ff:ff
16: example: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DEFAULT group default qlen 1000
    link/ether e6:ec:d2:7b:98:75 brd ff:ff:ff:ff:ff:ff

I would have just expected 15 to be created and 16 as a bridge, what are the other 2 interfaces for ?

this is internal plumbing, ln_ && pr_ are veth interfaces, like a virtual link, between bondv77 && exemple bridge.
