Description
Configure traffic forwarding options. For more information about each option, click a linked statement in the Syntax section.
Options
| access-security | Configure IPv6 access security options. |
| accounting | Specify the discard accounting instance name and options. |
| dhcp-relay | 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. |
| enhanced-hash-key | (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. |
| family | Specify address family for filters. |
| fast-reroute-priority | Specify the fast reroute priority for a VPLS routing instance. You can configure |
| helpers | 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. |
| inband-telemetry | Enable or disable the Inband Network Telemetry feature at the data path level, without intervention from the control plane. |
| ip-options-protocol-queue | 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. |
| link-layer-broadcast-inet-check | Enable destination MAC and IP address check to prevent the router from forwarding IPv4 packets that have link layer destination address set to |
| load-balance | 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. |
| load-balance-label-capability | 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. |
| multicast-replication | Configure the mode of multicast replication that helps to optimize multicast latency. |
| next-hop-group | Specify the next-hop address for sending copies of packets to an analyzer. |
| no-host-as-lpm |
Prevent host entries from overflowing into the LPM table when the host table is full. Configuring this restarts the PFE in standalone devices. Virtual Chassis (VC) devices require a manual restart. This restart removes any previously learned host entries from the LPM table. |
| no-load-balance-label-capability | Disable advertisement of entropy label capability in LDP and RSVP. |
| port-mirroring | Specify the input, output, and traceoptions properties for sending copies of packets to an analyzer. |
| rpf-loose-mode-discard | 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. |
| sampling | Configure traffic sampling. |
| storm-control-profiles | 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. |
