Hi Xiaodong
Yes and if i add an ip to the tap in Linux it also shows up in VPP. I'm
adding the full config at the end of the mail.
No I can't get an answer that's what I'm trying to achieve.

Hi Stefan,
Did you also enable 'linux-nl' plugin, in addition to 'linux-cp'? I
suppose 'linux-nl' is the one which syncs IP addresses/routes from
Linux to VPP.
BTW, were you able to get the IP address / route after you ran the
dhcp client on the tap interface? If not what do the error / log
messages look like?

Hi
I would like to use VPP with the lcpng plugin as a home gateway
where I
have to use dhcp to get an IP from my ISP. If I use the dhcp
plugin of
VPP it works and I can see an IP address on the interface on Linux
but
no route which was to be expected as lcpng doesn't sync routes
from VPP
to Linux.
Is it possible to use a dhcp client on Linux to get the IP and
routes on
Linux where they are synced back to VPP? I naively tried "lcp create
GigabitEthernet3/0/0 host-if ge0-3" in VPP and then "dhclient -v
ge0-3"
on Linux without success. Is there anything I have to configure or is
this not possible? I'm using VPP 23.02 with lcpng master.
Any help is highly appreciated.
Best regards,
Stefan
