“show plugin” will tell you which plugins are loaded. Note that the .so files
must be located in the same directory with all of the other plugins. Find
“dpdk_plugin.so”, etc.

Subject: Re: [vpp-dev] VPP with FRR Bring-up - not able to enable tap-inject
Hi folks,
I have made some code changes in VPPSB (the code changes are attached here),
with these changes I have re-compiled. I was able to successfully compiled vpp
with the netlink and router plugins. I have verified the router plugin contains
the correct symbols to enable tap-inject interface. But still can’t enable
tap-inject in VPP. I have stopped and started the VPP service. I am guessing
that VPP is not loading these two plugins.
I would appreciate if you have any workaround or suggestion to load VPP with
the router and netlink plugins.

Subject: RE: [vpp-dev] VPP with FRR Bring-up - Netlink and Router Plugin build
failures
Hi Balaji,
Thanks for replying. Yes, I have that wiki and followed that, may be it is out
dated. I have mentioned that in a different thread on yesterday (attached here).
I have tried to build from different release versions, initially with v18.10 as
mentioned in the wiki. Currently, I am v20.01. These plugins doesn’t build
properly.
Few issues –
1. I didn’t find ‘bootstrap.sh’ file under build-root dir as mentioned in
the wiki.
2. $ cd build-root/
3. $ ./bootstrap.sh
2. The VPP vnet/ip dir doesn’t contain ip6_neighbor.h, but it is included in
tap_inject_netlink.c
/root/vpp/src/vnet/ip
[root@localhost ip]# ls ip6*
ip6_error.h ip6_forward.h ip6_hop_by_hop.h ip6_input.h
ip6_ll_table.c ip6_ll_types.h ip6_punt_drop.c
ip6_format.c ip6.h ip6_hop_by_hop_packet.h ip6_link.c
ip6_ll_table.h ip6_packet.h ip6_to_ip4.h
ip6_forward.c ip6_hop_by_hop.c ip6_input.c ip6_link.h
ip6_ll_types.c ip6_pg.c
/root/vpp/build-data/../router/router/tap_inject_netlink.c:19:34: fatal error:
vnet/ip/ip6_neighbor.h: No such file or directory
#include <vnet/ip/ip6_neighbor.h>
1. The netlink build issue was discussed in the thread, but not sure what
was the resolution of it.

Subject: [vpp-dev] VPP with FRR Bring-up - Netlink and Router Plugin build
failures
Hi folks,
I wanted to start a new thread on the discussion related to VPP with FRR bring
up and get this working together for VPP as a Data plane with FRR as a Control
/Routing plane. Please chime in if you have already got VPP and FRR working
together or can help on the current issues.
I am currently facing issues to build VPP plugins for netlink and router.
1. Netlink build error -
I looked into the previous discussion on netlink compilation issues, I didn’t
find proper resolution for it. I made simple hack in the codebase and with that
I was able to build netlink lib. I am sure folks have gone through this issue,
so would like to know if any fix or patch is available.
