FastPath Handlers
Currently RouterOS has three fast path handlers
- ipv4 fast path
- traffic generator
- mpls fast path
- bridge handler
Note: Packet will be forwarded in fast path only if source and destination interfaces support fast path. See the list of supported interfaces.
IPv4 handler
IPv4 fast path is automatically used if following conditions are met:
- firewal rules are not configured,
- simple queues are not configured
- source interface is not bridge or bonding slave
- destination interface have configured only-hw-queue,
- no vrrp, mesh, metarouter interface configuration,
- sniffer, torch or traffic generator is not running
- connection tracking is disabled
/ip firewall connection tracking set enabled parameter has new auto value Which means that connection tracking is disabled by default until firewall rules are added.
Traffic Generator handler
Traffic Generator fast path is automatically used for interfaces that support this feature.
Bridge handler
Bridge fast path is automatically used if following conditions are met:
- ) bridge filter rules are not configured,
- )
/interface bridge settings use-ip-firwall=no, - ) destination interface has configured only-hw-queue,
- no vrrp, mesh, metarouter interface configuration,
- sniffer, torch or traffic generator is not running
Bridge fast path is approximately twice as fast.
