Juniper has built in policer to handle exceptional traffic like broadcast. When you configure any interface you will see a default policer associated with the interface.
Check for the 'show interface intf-name extensive' at the bottom you will see a default filter. Cherrs!!!

For example telnet, SSH or SNMP traffic. I guess it is technically correct to say that "incoming frames which have one of the router interfaces MAC addresses as a destination MAC address are exception traffic"? 2) IPv4 packets with options set. IPv6 packets with extension headers? 3) Packets requiring the generation of an ICMP error message. For example if IPv4/IPv6 packet comes in with TTL/hop-limit 1, then router has to send ICMP error message to destination. Are there any other exception traffic types? When is broadcast and multicast traffic handled as exception traffic? thanks, Martin _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp _________________________________________________________________________________________________________________________ Ce message et ses pieces jointes peuvent contenir des informations confidentielles ou privilegiees et ne doivent donc pas etre diffuses, exploites ou copies sans autorisation.
