"CSR source route insecure. DROP IT" drop code

Products

• VMware VeloCloud SD-WAN

Issue/Introduction

When attempting to reach a destination within an NSD, there were drop codes which stated the following:

24/11/11 22:59:02.448181,504|7|14090/84327|edged_ipv4_handle_route_fail:8262 No valid src/dst route for pkt [src=X.X.X.X] [dst=X.X.X.X], seg 0, sroute=(nil) droute=(nil) lookup failed due to [CSR source route insecure]. DROP IT.



Cause

A switched port that was configured was changed to a routed port. This caused the static routes interfaces to be marked as "N/A". Which also marked them as Reachable: False

Resolution

After the interface configuration was changed, the static routes needed to be reconfigured to include the new routed interface.

VCO release 6.1.0.1 now has a validation error when attempting to make this change.
