In this webinar, we discuss a feature from mikrotik routerOS that is called fastpath. This feature will improve routerboard performance by increasing number of packet per second and lowering CPU usage. Fastpath requires several conditions to be active, and the webinar is talking about them. the recording is available on youtube (GLC Networks Channel): https://www.youtube.com/channel/UCI611_IIkQC0rsLWIFIx_yg

Drawbacks of slowpath
● SLOW -> lower performance -> lower
packet per second
● Packets should go through many processing
post -> higher CPU usage

10. www.glcnetworks.com
Can we improve slowpath?
Yes -> fastpath
● Just skip the processing posts (in
case you dont use them)
● This will improve routerboard
performance

Fastpath conditions (1)?
YES. fastpath will active if following conditions are met (aka. handler)
● IPv4 handler
○ firewal rules are not configured;
○ firewall address lists are not configured;
○ Simple and queue trees with parent=global are not configured;
○ no mesh, metarouter interface configuration;
○ sniffer, torch and traffic generator is not running;
○ connection tracking is not active;
○ ip accounting is disabled (/ip accounting enabled=no);
○ VRFs are not set (/ip route vrf is empty);
○ Hotspot is not used (/ip hostspot has no interfaces);
○ IpSec policies are not configured (ROS v6.8);
○ /tool mac-scan is not actively used;
○ /tool ip-scan is not actively used;
○ route cache must be enabled
○ /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.

Fastpath conditions (2)?
● IPv4 FastTrack handler
○ FastTrack is available on the devices with FastPath support.
● Traffic Generator handler
○ Traffic Generator fast path is automatically used for interfaces that support this feature.
● MPLS handler
○ MPLS fast path is automatically used for interfaces that support this feature.
○ Currently MPLS fast-path applies only to MPLS switched traffic
● Bridge handler
○ no bridge firewall rules (/interface bridge filter, /interface bridge nat) are configured,
○ /interface bridge settings use-ip-firwall=no,
○ no mesh, metarouter interface configuration,
○ sniffer, torch and traffic generator is not running,

Is my routerboard supported by Fastpath?
● Almost all routerboard support fastpath
● To check physical interface: /interface print detail
13

14. www.glcnetworks.com
Fastpath supports virtual
interface?
Yes.
● more and more virtual interfaces will
be added to support fastpath
● To check: /interface print detail
○ Check “allow fast-path”
