Unable to access slice

[Kriti Goel]

Hi,

For the past 2-3 days, every time I create a slice and work on it for a few hours, I encounter the following error:

“From 192.168.24.254 icmp_seq=1 Destination Net Unreachable.”

SLICE_NAME = “ospf_13node”
SITE_NAME = “MASS”

I created multiple different slices on different sites but still the issue persists.

And for the slice extension using  the Calendar by clicking on the small square shown next to Lease End at to choose the timestamp and then click on Extend, that is also not working. I’m using the script to extend the slice.

Hi Kriti,

I created a slice on MASS for a Layer2 Network as well as Layer3 network. Both slices were able to pass traffic.

This may be something specific to your slice or configuration. Please share your slice id. We can help to take a look but would also recommend checking configuration on your side as well.

Thank you for letting us know about the portal. We will work on addressing that as well.

Thanks,

Komal

Hi Kriti,

It appears that there may be a configuration issue with your experiment. I recommend checking your settings. Based on your slice, there’s a Layer 2 network established between ipnode-1 (192.168.14.1) and n6 (192.168.14.254).

I can confirm that pinging from ipnode-1 to n6 is successful, which indicates that the underlying Layer 2 network is functioning properly. While you do have a route on ipnode-1 to direct traffic through n6, it seems that the subnet you’re trying to access is not reachable from n6. This issue seems to be specific to your experiment’s configuration, so you may need to troubleshoot on your end.
