I'm having this issue where I have a P2P link between two sites. The moment I would unplug cable from the existing port on one side to another port (say in a router), what happens is that the ISP switch detects a change in MAC address at their end and consequently disables their port (as per them, its a security measure). This is annoying as I can't even do my testing. What I have done is that currently one end of the link terminates into a Cisco Gigbit switch 2960 G. I've enabled BPDU guard command and it works fine. Now, i want to terminate this into an HWIC-4ESW card on a 2800 series router. Can I issue the same command on my router's int f0/0/0 so that it stops sending any BPDUs to the ISP switch, otherwise ISP is going to shut down the port at their end and I loose connectivity.
Given below is the current config of the switchport for bpdu. Can I do anything like this on HWIC-4ESW interface of the router so that it stops sending any BPDUs ?
LANSwitch1#sh running-config interface gigabitEthernet 0/20
Current configuration : 133 bytes
spanning-tree bpdufilter enable
