I'm trunked to my internet service provider for a ethernet handoff. I keep recieving:
%SW_VLAN-4-VTP_USER_NOTIFICATION: VTP protocol user notification: Version 1 device detected on Gi1/26 after grace period has ended
I am using version 2 but thats not the point. I do not want the isp receiving any vtp advertisements, joins, etc.
How do I prevent port g1/26 from receiving vtp advertisements?
I need the rest of my network to receive vtp.
I think the way is to configure ur vtp mode as transparent so that the vtp need not be propogated to isp.The only thing is u need to then manualy configure for the vlans.
Another method that came 2 my mind is to block the multicast mac address (0100.000c.cccc) on which vtp messages are send using mac access-list.but the problem is the same mac is used by DTP messages also.so i thing its better to trunk unconditionaly(ie,nonegotiation)and then block the vtp messages on the interface..
