They are set static. I'm going to see if a problem device has lost its gateway setting, as soon as I figure out how to access the interface. ------------------------------ JOHN WILLIAMSON ------------------------------

Are the devices DHCP or static addressed? If they are DHCP perhaps they are failing in lease renewals and that is why they drop off apparently randomly. Or perhaps the devices in low power mode or similar are bouncing the ports and the dynamic port ...

Do all devices on vlan 93 use the gateway on the core switch as their gateway or default route? Yes. Or at least, they were all supposed to. We had a vendor install an A/V system in every classroom in the school district and I gave them the network ...

Securing your IGP is great. Securing your iBGP, no that much. First BGP is a protocol using TCP (so you already have the TCP segment numbers protecting somewhat introducing stuff in the flow). Second, in my experience, I've seen catastrophic failures ...

Since the trace route dies at the core there is a reachability issue between the mgmt vlan and vlan 93 in this case. Are all gateways for the vlans on the core switch? Is the mgmt vlan gateway on the core switch the default route destination configured ...

I could still use some help understanding this issue. In a nut shell, why can I ping a device at a school on the core switch but not on the switch the device is plugged into or anywhere else in our school district? What could be different about this ...

Thanks for your answer of my question. I will shortly explain, why we wan to secure our bgb roote reflector. Wer operate like you our own backbone and we have like youl full controll over the end-to-ens paths between the mpls router. The idea, to ...
