They are by default. See

"Cisco IOS assigns an IP precedence of 6 to routing protocol packets
on the control plane. As noted by RFC 791, "The Internetwork Control
designation is intended for use by gateway control originators only."
Specifically, Cisco IOS marks these IP-based control packets: Open
Shortest Path First (OSPF), Routing Information Protocol (RIP),
Enhanced Interior Gateway Routing Protocol (EIGRP) hellos, and
keepalives. Telnet packets to and from the router also receive an IP
precedence value of 6. The assigned value remains with the packets
when the output interface transmits them into the network."
