[c-nsp] Static Inter-VRF Routing on VSS 1400 not working with 12.2(33)SXI6

[Friedrich, Gregor]

Hello 

We are trying to migrate an  existing configuration form an older 6500  with SUB 720 and  12.2(17d)SXB1 to  VSS system. There are 10 VRF used. Some subnets are static routed between some VRFs (Inter-VRF Routing) like:  ip route vrf AAA 172.24.192.0 255.255.248.0 Vlan400 172.24.193.1 

On the older 6500 this configuration is running fine since years. But on the new system it works not, I cannot ping the SVI in different VRFs and also not from any host in  vlan 100 to any  host in  vlan 400 . I s this behavior  documented? 

 If I try  "VRF SVI to VRF SVI"  ping i get a traceback:
