Subject: [vpp-dev] IGMP enable issue
Hello,
I am trying to configure VPP for IGMP, but with this configuration it seems
doesn't work:
vpp# igmp listen enable int GigabitEthernet0/3/0
vpp# sh igmp config
vpp# trace add dpdk-input 10
vpp# sh trace

igmp-input: IGMP not enabled on this interface
Source host: Linux a 4.9.0-6-amd64 #1 SMP Debian 4.9.88-1+deb9u1 (2018-05-07)
x86_64 GNU/Linux, IP 172.16.1.1
Target: VPP v18.10-rc0~248-g4553c95a on VM, compiled with GCC 6.3.0 20170516,
IP 172.16.1.2
Multicast group address: 224.0.0.22
As you can see, the command "sh igmp config" shows nothing, and trace is
reported error: IGMP not enabled on this interface.
Could you help me with this? Thanks a lot.
Regards,
Aleksander
