Hi Guy,
If that’s the full packet trace, then it looks like the packet was dropped by
an input feature. Use:
sh int feat <INPUT_INTERFACE>
To see what’s configured. Do you have an IP address configured on the input
interface? You’ll need one.
If it’s not that, do you have a route for 232.0.0.1 in the multicast FIB? If so
what is it:
sh ip mfib 232.0.0.1
Regards,
Neale

Subject: [vpp-dev] problem getting udp_register_dst_port interface to work.
I am trying to process the following packets using the udp_register_dst_port
interface:
UDP: 10.10.10.34 -> 232.0.0.1
tos 0x00, ttl 0, length 1428, checksum 0x792c
fragment id 0x0000, flags DONT_FRAGMENT
UDP: 1234 -> 5001
length 1408, checksum 0x0000
01:22:29:244229: ip4-input-no-checksum
UDP: 10.10.10.34 -> 232.0.0.1
tos 0x00, ttl 0, length 1428, checksum 0x792c
fragment id 0x0000, flags DONT_FRAGMENT
UDP: 1234 -> 5001
My registration function below is getting called:
#define UDP_DST_PORT_stream 5001
udp_register_dst_port (vm, UDP_DST_PORT_stream,
udp4_test_node.index, 1 /* is_ip4 */);
But I never get a call when packets are received. Any idea what could be going
wrong or how to debug this?
Thanks,
Guy
