    • Type: Bug
    • Status: Resolved (View Workflow)
    • Priority: Major
    • Resolution: Fixed
    • Affects Version/s: 2.2.0
    • Fix Version/s: None
    • Component/s: None
    • Labels:
    • Environment:
      • Two IS-IS routers
      • BGP Configured on one of the routers
      • ONOS 2.2 connected to router using BGP

      Description

      Steps to reproduce:

      1. Connect two routers, R1 and R2 via IS-IS
      2. Configure BGP on R1
      3. Connect R1 to ONOS via BGP (To check, use "devices" and "links" command in karaf console. R1 and R2 are seen in devices command and R1->R2 and R2->R1 links are seen in links command)
      4. Turn off R2

       Expected Output:

      1. Links should disappear from "links" command
      2. R2 should disappear or shown as isReachable = false

       Actual Output:

      1. Links disappear
      2. R2 is shown as isAvailable=true, isReachable=true

       

      Note : We could see from packet captures that proper MP_UNREACH_NLRI is received on ONOS, so theoretically R2 should become isReachable = false
