Dear All,
I am trying to evaluate the support of pppoe in vpp. However, I am facing
some issues, here is my startup conf file.
unix {
nodaemon
log /var/log/vpp/vpp.log
full-coredump
cli-listen /run/vpp/cli.sock
gid vpp
}
api-trace {
on
}
api-segment {
gid vpp
}
socksvr {
default
}
cpu {
main-core 1
corelist-workers 2,4,3,5
}
dpdk {
dev 0000:05:00.1
uio-driver vfio-pci
socket-mem 2048,2048
}
plugins {
plugin default { enable}
}
tuntap {
enable
ethernet
name newtap
}
After that I run the following commands:
vpp# set interface state TenGigabitEthernet5/0/1 up
vpp# set interface state local0 up
Now at this point if I try to connect from the pppoe client, I can see three
PADI request reaching VPP, and VPP trying to forward them at local0
interface.
To forward this traffic to the tap port instead, I use this command.
vpp# create pppoe cp cp-if-index 2
The help and the documentation for this command show this "create pppoe cp
if-name <intfc> [del]", which doesn't work.
Now at this moment, I was expecting the VPP to forward the PADI request to
tuntap-0 interface, but I don't see anything in the VPP counters, nor by
using tcpdump on interface "newtap" which is the kernel facing side of
"tuntap-0" interface.
My question is, Is my approach correct? Are the PADI requests forwarded to
the tuntap-0 interface? If not where do they go? I cannot find any good
documentation on this anywhere.
Any help regarding this would be highly appreciated.
Regards,
Alp Arslan
