vEOS MLAG won't come up due to auto generated mac addresses

[nanisyako]

it seems auto-generated macs causing mlag issues:

GNS3/gns3-gui#2475

I tried to change that in /vrnetlab/veos/docker/vrnetlab.py

def gen_mac(last_octet=None):
""" Generate a random MAC address that is in the qemu OUI space and that
has the given last octet.
"""
return "0C:54:00:%02x:%02x:%02x" % (
random.randint(0x00, 0xff),
random.randint(0x00, 0xff),
last_octet
)

but somehow after running "make" it returns to the original value and the device booted from that image still has the macs that start with 52:54 instead of 0C:54 . I think after running make, the docker image installs a new vrnetlab.py

@monrad , could you have a look please?

vrnetlab.py is copied in from common/vrnetlab.py by the Makefiles so you would need to modify common/vrnetlab.py or the better way is to override the gen_mac function specifically for veos.

Awesome, thanks a lot, @plajjan. Yeap, that fixed it. Once I figure out how to selectively do it for vEOS, I can create a pull request
