vRtrPimNgInvalidIPmsiTunnel

Table 11. vRtrPimNgInvalidIPmsiTunnel properties
Property name	Value
Application name	PIM
Event ID	2014
Event name	vRtrPimNgInvalidIPmsiTunnel

Default severity	warning
Source stream	main
Message format string	Received intra-as a/d route with invalid i-pmsi tunnel group address $vRtrPimNgWrongMdtDefGrpAddr$ from $vRtrPimNgNotifySourceIp$, expected $vRtrPimNgAFGenMdtDefGrpAddress$
Cause	The vRtrPimNgInvalidIPmsiTunnel event is generated when an invalid default core group address specified by vRtrPimNgWrongMdtDefGrpAddr of the Multicast Distribution Tree(MDT) is received in PIM message from vRtrPimNgNotifySourceIp, instead of the expected address specified by vRtrPimNgAFGenMdtDefGrpAddress.
