Hi,
I am seeing an issue running kea-dhcp4 on multiple interfaces configured as
ip unnumbered.
Here is my interface configuration. rt1_0_1 and rt1_0_2 are both sharing
the same IP address on a loop[back interface.
rt1_0_1 Link encap:Ethernet HWaddr 50:9a:4c:e9:c0:73
inet addr:192.168.200.2 Bcast:192.168.200.2 Mask:255.255.255.255
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
rt1_0_2 Link encap:Ethernet HWaddr 50:9a:4c:e9:c0:73
inet addr:192.168.200.2 Bcast:192.168.200.2 Mask:255.255.255.255
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
When I run kea-dhcp4 on rt1_0_1 and rt1_0_2, it complains while opening
socket for rt1_0_2 as 192.168.200.2:67 is already used for rt1_0_1.
If I configure to run kea-dhcp4 only on loopback interface then it does not
listen on rt1_0_1 and rt1_0_2 and the dhcp requests are dropped.
Is there a way to make kea-dhcp4 work in this use case?
Thanks,
Avoy
