S4148 OS 10.5 - Cannot pass inter-VLAN routing on instance vrf
I can't get routing to pass through the vrf instance

Traceroute from 10.240.8.64/26 stop on interface vlan3950
Traceroute from 10.128.0.0/24 stop on interface vlan3048
It seems the switch is not passing inter-vlan traffic, but on vlan IP is assigned and interface is in "no shutdown" state

Simone Barucco,
Would you confirm if this is the initial configuration of the switch, as you will likely need to call in for assistance. If not then I would say we definitly need additional information, such as the results of show vrrp as well as the results of show tech-support. You can upload the results on upload. dell. com, then private message me the svc tag used to upload, so I can locate the logs. I can then review them for you to see if I can spot anything.
Let me know.

Hello Simone Barucco,
Can I clarify this is a new configuration since things have change from initial configuration?
Could you log the output of this command:
console#show tech-support
Then upload here, https://upload.dell.com/, under the service tag of the switch and Private Message Chris and myself the service tag so that it can be retrieved for review.

I actually found that the traffic works in one direction now, whereas before it stopped at the switch.

Simone,
After reviewing the logs I am not seeing anything standing out. What I would suggest, based on your warranty, is to call in to support so they can directly analyze the issue with you.

Simone Barucco,
Just a thought, did you happen to run the redistribute connected command, after connecting?
