[c-nsp] Internal BGP routes redistributed into OSPF w/o bgp redistribute-internal

[Friedrich, Gregor]

Hi list 
 

I have a strange behavior with redistributing BGP Routes (no internet!) into OSPF inside an VRF on ASR1001-HX running IOS-XE 16.3.4 

Network statements are redistributed into OSFP  *without* to  configure "bgp redistribute-internal" !

That isn't a normal behavior, right? It should happen, if " bgp redistribute-internal" It's not happen in IOS-XE on Cat. 4500X 3.6.02E

Any hint?
