dpdk-udp to linux-udp is not working between devices #103

Closed jihwanseo closed 5 years ago

jihwanseo commented 5 years ago

Hi. ANS Team.

I'm facing some issue about UDP test. I'm trying to test udp between dpdk_udp_stability and linux-udp. When i try to run these in the same device. it's working fine. However it seems like it is not working between other devices. dpdk_udp_stability can receive data from linux-udp app. but linux-udp can't receive response data from dpdk_udp_stability. (I use ip address 10.113.174.184 in the test apps) Anyone who know what i miss something?

please refer below setup

If you use different IP, you shall change the hardcode IP in dpdk_udp_stability. By the way, what IP is used in linux-udp? if it is in different subnet, you shall also configue the default route.

jihwanseo commented 5 years ago

Yes. I changed hardcode IP in dpdk_udp_stability (10.113.174.184) 10.113.175.70 is used in linux-udp. Can you tell me how to config the default route?

bluenet13 commented 5 years ago

anscli> ip route add 0.0.0.0/0 via x.x.x.x
