we've Cat 3560 running IP Base image (switching only on L2), with several 802.1q trunks:
- 2 are connected to routers/firewalls
- others are connected to other L2 switches,
- each trunk contains over 40 Vlans
The routers/firewalls are "virtualized" using VRRP. I'l like to limit propagation of VRRP only to 3560, without flooding the information to other L2 switches. I tried to block the traffic (multicast IP address 188.8.131.52, MAC address 0100.5e00.0012) using
switchoport block multicast
mac-address-table static 0100.5e00.0012 vlan X interface A,B (A and B interfaces are the routers/firewalls)
but I didn't succeeded. Do you have any idea what to try?
