 Description   

Currently there are issues in NEP route builder algorithm when encountering a tunnel path in the route path. To solve this issue the below algorithm is proposed.

1. When encountering a routing table information withe a tunnel path the interpretation of the routing table info should be as follows.

  • To reach to the specified destination network - > go to this next hop router - > Via the tunnel specified.
  • Attached the routing table info for route of 4G node LM17130 in the router routing table.
    2. The tunnel path can be determined from the tunnel path configuration information. By going thorough each next hop step by step using the routing table information. Attached the routing table info for the tunnel configuration information on a router in the path of node LM17130.
    3. Corresponding NEP screenshots of the information's also attached.

  • New rules for tunnel was implemented in patch 3.7.0.1290.
  • Still checking the tunnel build issue.

for Tunnel, it's data issue , IP 62.231.253.177 is not configured on the right interface

LM17130 - is isolated now.

Awaiting to close it if we see it is fully fixed

Comment by Bessem Manita [ 01/Jul/25 ]

Release 3.7.0.1315 – Additional Fix

Core RB: Automatically create a virtual link if the expected link is not found during processing.

Release 3.7.0.1312 – Additional Fix

Tunnel Build: set source and destination nodes for virtual links during tunnel creation.
