This is perfectly normal spanning-tree behaviour - if edge ports didn't send BPDUs and you looped a cable between two edge ports then broadcast storm hilarity would ensue.
If you want to stop this from occurring (and have a good understanding of the implications of doing this between two switches), disable RSTP on the interface: set protocols rstp interface ge-0/0/0 disable If you're just trying to keep your RSTP topology separate but want to keep the protection mechanisms in place, use root-guard: set protocols rstp interface ge-0/0/0.0 mode point-to-point set protocols rstp interface ge-0/0/0.0 no-root-port If you're carrying traffic for your customer from one site to another (Q-in-Q) and they need their spanning-tree topology maintained transparently across your network, then you'll need to use dot1q-tunneling: set vlans CUST-A-OUTER dot1q-tunneling layer2-protocol-tunneling stp set vlans CUST-A-OUTER dot1q-tunneling layer2-protocol-tunneling vstp On 23/03/2011, at 8:10 AM, Pavel Dimow wrote: > Hi, > > I have strange situation where my customer receives bpdu's on his > cisco switch from my ex4200 despite the fact that I have configured my > port as access (default in JUNOS) > and as edge on rstp configuration.
