vlan flooding VOSS 8.1.0.0

[Stephane_Lemair]

Hello,

Since I upgraded my fabric to VOSS 8.1.0.0, I experience vlan flooding. I receive all traffic of a vlan on each ports belonging to the vlan. It’s the same behavior for every VSP 7200 an 8400 in the fabric in 8.1.0.0.

Does anyone have the same issue ?

Thanks,

Hi Roger,

could you explain what you mean with a next hop filter?

We dont use any Filters to our knowledge.

Thanks

Are you using Forward to next hop filters on two switches?

Hi Roger,

we have a similiar flooding issue but just in one of our VLANs since the Update from 6.0.1.2 to 8.0.7.0.

Could you explain your solution.

Thanks

quick update on this: The issue that was seen in this case was related to a InVSN forward to next hop filter that was pointing to another InVSN forward to next hop filter that was pointing back to the original device. Adjusting the filters resolved the flooding. So there is NO flooding issue with VSP release 8.0 nor 8.1.

ok, thanks. We will look into it with support/engineering. Will provide an update for the rest of the readers once we know more.
