NX-OS (Nexus 7k) to block/filter traffic between vlans.

[navnath.dighe]

I am working on a solution to block traffic between two vlans communications. . When I tested connectivity between vlans,  traffic is passing. I have configured VRRP protocols for l3  vlans  and 99 vlans  created on nexus7k. Please guide me how to block/communications between vlans.

show us your ACL or configuration how you have configured. simple ACL should deny the traffic between VLAN

Hello,

you can use access lists or Vlan access list (VACLs). VRRP adds a bit of complexity, as you need to allow UDP port 8888 (that is the port VRRP uses as far as I recall).
