Subject: Standard VPP functionality for AD4,AD6,AS4,AS6
Team
Wish to share our observations on validating AD4, AD6 ; AS4 & AS6 functionality
using VPP . We faced issues compared to AD2 (Eth) functionality testing and
following is the summary
For AD2: In Egress packets are getting received from VM's (QEMU VM)
vhost-user-input which is sibling of device-input
For AD4: In Egress packets are getting received from vhost-user-input, so here
packets are going to ethernet-input node which are received from virtual
interface and pkt is getting dropped in Ethernet because of wrong mac. As the
AD4 feature is enabled in ip4-unicast arc, packets are dropped even before
coming to this arc.
/* *INDENT-OFF* */
VNET_FEATURE_INIT (srv6_ad2_rewrite, static) =
{
.arc_name = "device-input",
.node_name = "srv6-ad2-rewrite",
.runs_before = VNET_FEATURES ("ethernet-input"),
};
VNET_FEATURE_INIT (srv6_ad4_rewrite, static) =
{
.arc_name = "ip4-unicast",
.node_name = "srv6-ad4-rewrite",
.runs_before = 0,
};
We have modified the code to receive the packet from device-input as below
VNET_FEATURE_INIT (srv6_ad4_rewrite, static) =
{
.arc_name = "device-input",
.node_name = "srv6-ad4-rewrite",
.runs_before = 0,
};
After this change, we see its working fine, wish to check if our observation
fine along with code changes.
Also we would like to know what setup you have used to act as VM ?? that is,
whether you have used vhost-user-input for sending and receiving packets
to/from VM respectively.
