forwarding-options (Routing Instance)

Configure IPv6 access security options.

Specify the discard accounting instance name and options.

Configure extended Dynamic Host Configuration Protocol (DHCP) relay and DHCPv6 relay options on the router or switch to enable the router (or switch) to function as a DHCP relay agent.

(MX Series routers with MPCs, T4000 routers with Type 5 FPCs, and EX9200 switches) Select data used in the hash key for enhanced IP forwarding engines.

Specify address family for filters.

Specify the fast reroute priority for a VPLS routing instance. You can configure high, medium, or low fast reroute priority to prioritize specific VPLS routing instances for faster convergence and traffic restoration.

Enable TFTP or DNS request packet forwarding, or configure the router, switch, or interface to act as a DHCP/BOOTP relay agent. Enable forwarding LAN broadcast traffic on custom UDP ports to particular servers as unicast traffic.

Configure logical queue-depth in the PFE for ip-options packets for a given protocol such as TCP, UDP, ICMP, and so on, except IGMP.

Enable destination MAC and IP address check to prevent the router from forwarding IPv4 packets that have link layer destination address set to broadcast or multicast, unless directed to an IPv4 multicast address.

Enable per-prefix or per-flow load balancing so that the router or switch elects a next hop independently of the route selected by other routers or switches.

Enable the router to push and pop the load balancing label and causes LDP and RSVP to advertise the entropy label TLV to neighboring routers.

Configure the mode of multicast replication that helps to optimize multicast latency.

Specify the next-hop address for sending copies of packets to an analyzer.

Disable advertisement of entropy label capability in LDP and RSVP.

Specify the input, output, and traceoptions properties for sending copies of packets to an analyzer.

Configure unicast reverse path forwarding (unicast RPF) loose mode with the ability to discard packets with the source address pointing to the discard next hop.

Configure traffic sampling.

Configure a storm control profile on a switch or router. Storm control is used to prevent network outages that are caused by broadcast traffic storms.
