Our peering setup is a follows: - Our peering exchange connection goes into switch A - Switch A has a dark fibre connection to switch B, which is in a different PoP - Our peering router is connected to switch B We use spanning tree across our network to allow the VLANs connectivity across our network. The peering exchange has an MoU that only 1 MAC address should be visible on their switch. However they see 2 MAC addresses on our port. - MAC address of Peering router - MAC address of the port they are connected to on switch A Is there any way to prevent switch A from presenting the interface MAC address? Or is this a symptom of spanning tree that cannot be stopped? Your input will be most welcome. The config on switch A is as follows: interface GigabitEthernet0/5 description Peering Link switchport access vlan 148 switchport mode access speed nonegotiate storm-control broadcast level 5.00 no cdp enable spanning-tree portfast spanning-tree bpdufilter enable spanning-tree guard root Regards Simon Brilus
