Hi Artem, I think that is telling you not to use /32 address on interface for which you expect there to be connected peers. >From an IP networking perspective, if you want two peers to be connected on an >interface, they need to be within the same subnet, so use a /31.

For example, memif. When I'm creating memif interfaces and run ping I see: DBGvpp# ping 10.10.2.1 Failed: no source address for egress interface ... But it is worth mentioning that I am setting /32 mask for IP address Managed to fix IP mode with these patches: https://gerrit.fd.io/r/c/vpp/+/32801, https://gerrit.fd.io/r/c/vpp/+/33303 But Ethernet mode still doesn't work. ============================== There was already a similar topic: https://lists.fd.io/g/vpp-dev/topic/84038840 Created a jira issue with details: https://jira.fd.io/browse/VPP-1992 Does anyone have any thoughts on this? Thank you.
