  • 1.  Restrict inter-vlan routing on ex 3200

    Posted 09-06-2012 14:45
    I'm very new to juniper switches but have some experience with catalysts.

    I'm looking to have allow only specific vlans route to specific vlans rather than "all to all". On Cisco this is done through acls, is this possible on juniper?

    Thanks

    The feature you want to configure is a "firewall filter".  These are stateless packet filters that can match particular conditions and block or allow the traffic at an interface.  THey work in a manner very similar to Cisco ACLs.
