TitleISIS WARNING plsbScAddRouteToRTM:VrfId:0 Unable to add REMOTE ISIS route
Symptoms
The log displayed the following 
GlobalRouter ISIS WARNING plsbScAddRouteToRTM:VrfId:0 Unable to add REMOTE ISIS route 204.130.13.32/255.255.255.240 in RTM, SrcVrfId:0 Vlan:4051 Cost:20 Bmac:00:02:02:82:00:00

 
Environment
  • VSP 8242XSQ
  • SW 6.1
Cause
There is a timing issue when the switch makes an attempt to add the route(s) to the RTM (Routing Table Manager) when a route or routes has already been learned via OSPF on each of the peers w/ different metrics and the switches are configured to have the OSPF routes redistributed into ISIS, via a metric type of external. 

    Timing issue
    The OSPF maxage of the LSA & advertising of the new sequence number is being performed quickly triggering a timing issue. During this period, ISIS is making an attempt to replace the existing OSPF route. This is not allowed, hence the reason for the log message.
    Resolution
    Functioning as designed, this message is informational.
    Additional notes
    This was put in place by design on the VSP switches to note this activity.
