[j-nsp] L2 flooding

[Johan Borch]

Hi!

I have a L2 network with a core and a bunch of access switches, all juniper
EX. The links between the access switches and the core are marked with vlan
all and trunk.

Here's to my problem. I'm deploying a CEPH cluster and the cluster is
running on it's own vlan. This vlan only exists on the core and on one
other switch. The problem is that CEPH is very chatty and due the fact that
the core links accepts all vlan the core floods the traffic to all other
switches and fills upp the uplinks (even if the vlan don't exists on those
switches). Is there some way to mitigate this except the obvious to not run
vlan all on the uplinks and to move ceph-cluster to it's own switches?
