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
|
|
|
|
# brctl addbr vrrpbr
|
|
# brctl addif vrrpbr veth0-br
|
|
# brctl addif vrrpbr veth1-br
|
|
# brctl addif vrrpbr veth2-br
|
|
|
|
|
|
# ip link set veth0 up
|
|
# ip link set veth0-br up
|
|
# 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
