[LS-272] NEP not checking the sub interface for IP route/ route builder

Wed, 28 May 2025 10:08:32 +0300

While performing IP route on failed route builder cases, the IP route algorithm doesn't check the exact source interface which is the sub interface but instead it takes the interface as the source interface. Due to this it is not able to check the correct routing table and hence failing to build the route.

Attached screen shots for node BD02870 with source GW: 10.116.10.1 and destination GW: 10.238.250.2, " with main failure reason of Destination IP unreachable in route builder ".
Also attached screen shots for node LB00010 with source GW: 10.238.143.1 and destination GW: 10.238.250.54. " with main failure reason of Next Hop IP missing for Router in route builder"
