Usage:
osken-manager --verbose \
os_ken.services.protocols.vrrp.dumper \
os_ken.services.protocols.vrrp.sample_manager.py \
os_ken.tests.integrated.test_vrrp_linux_multi \
os_ken.app.rest
os_ken.services.protocols.vrrp.dumper is optional.
os_ken.app.rest is merely to prevent osken-manager from exiting.

/--<--veth0-->| |
OSKen | linux bridge |<--veth2--> command to generate packets
\--<--veth1-->| (vrrpbr) |
----------------
# ip link add veth0 type veth peer name veth0-br
# ip link add veth1 type veth peer name veth1-br
# ip link add veth2 type veth peer name veth2-br
# ip link add vrrpbr type bridge
# ip link set dev veth0-br master vrrpbr
# ip link set dev veth1-br master vrrpbr

# ip link set veth1 up
# ip link set veth1-br up
# ip link set veth2 up
# ip link set veth2-br up
# ip link set vrrpbr up
if you like, capture packets on each interfaces like
# tshark -i vrrpbr
# tshark -i veth0
# tshark -i veth1
# tshark -i veth2
virtual router mac address: 00:00:5E:00:01:{VRID} = 00:00:5E:00:01:07
during working, send packets destined to mac address 00:00:5E:00:01:07
from veth2 by packet generator like packeth
NOTE: vrid: 7 and ip address: 10.0.0.1... are hardcoded below
