Unable to Receive RTM_NEWNEIGH Netlink Messages for Interfaces in a VRF

[firasrasmy-thg]

I am using pyroute2 to listen for netlink RTM_NEWNEIGH messages on an interface that is part of a VRF. However, no netlink messages are received for the interface under the VRF. The same code works fine for interfaces not assigned to a VRF.

Code:

with IPRoute() as ipr:
    ipr.bind()
    while True:
        for message in ipr.get():
            print(message)
            if message['event'] == 'RTM_NEWNEIGH':
                attrs = dict(message['attrs'])
                if not attrs.get('NDA_LLADDR', None):
                    print(f"Null route: {attrs['NDA_DST']}")
                else:
                    print(f"{attrs['NDA_DST']} is alive!")
        time.sleep(1)
