NEP route builder algorithm issues when encountering a tunnel interface.

        Details

        • Customer:
          OMAN-Tel
        • Complexity:
          High
        • Severity:
          Major

          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.
