Hi Abeeha,
Have you tried the suggestion I made previously in a similar thread to get rid
of the dummy_interface_tx nodes for PPPoE sessions?
diff --git a/src/plugins/pppoe/pppoe.c b/src/plugins/pppoe/pppoe.c
index d73a718..f61926d 100644

hw_if_index, u32 flags)
VNET_DEVICE_CLASS (pppoe_device_class,static) = {
.name = "PPPoE",
.format_device_name = format_pppoe_name,
- .tx_function = dummy_interface_tx,
+ // .tx_function = dummy_interface_tx,
.admin_up_down_function = pppoe_interface_admin_up_down,
};
/* *INDENT-ON* */
I believe this would prevent creation of TX nodes for PPPoE sessions which are
not used anyway. Then you should not encounter any problem with node index
assert error.
If it does work, please submit this patch via gerrit.fd.io so it can be merged
upstream.
Regards,
John

Dear Hongjun,
(PFA = Please find attached)
Code:
Branch: stable/1901
Patch: PFA: stable_1901_patch.txt
Configuration:
PFA: vpp-startup.conf
Steps for setting up:
PFA: setup_steps.bash
Attempted to make 10,000 connections.
Using API calls from control plane application; to create pppoe sessions
Final output from control plane before VPP crashed:
PFA: no_of_connections.png
VPP log-file:
PFA:vpp.log
Dump from journalctl:
PFA: journal_dump.txt
As you can see from the journalctl output, the code crashes on the Assertion
‘node_index < 2^14’. And as you can see from the patch file included, we
changed the original assertion from ‘less than 2^10’ to ‘less than 2^14’. We
did that, because the original assertion crashes VPP way before even 7,000
connections are connected. (Around 400 connections.)

Hi Aqeel,
Could you send out the core dump log when VPP crash with 7000 sessions?
Thanks,
Hongjun

Subject: VPP PPPoE Plugin
Dear Hongjun,
I am trying to create 64000 VPP sessions with the VPP Plugin. VPP is being used
as the forwarding plane while our control plane separately caters the PPPoE
control packets. The VPP is installed on Centos 7 on bare-metal server. The
current implementation of the plugin included in VPP Stable 19.01 is allowing
only 7000 sessions and VPP crashes afterwards.
I tried to add the PPPoE plugin implemented by OpenBRAS
(https://gerrit.fd.io/r/#/c/7407/) to the VPP Stable 19.01 (
https://github.com/FDio/vpp.git) with DPDK 18.11.0. VPP built successfully
and started as well but the PPPoE plugin did not show in “vppctl show plugins”.
Kindly, suggest how to connect 64000 pppoe sessions with VPP.
Regards,
Abeeha Aqeel
