RTFM, man routed,
DESCRIPTION
Routed is a daemon invoked at boot time to manage the network routing
tables. It uses Routing Information Protocol, RIPv1 (RFC 1058), RIPv2
(RFC 1723), and Internet Router Discovery Protocol (RFC 1256) to maintain
the kernel routing table. The RIPv1 protocol is based on the reference
4.3BSD daemon.
It listens on the udp(4) socket for the route(8) service (see
services(5)) for Routing Information Protocol packets. It also sends and
receives multicast Router Discovery ICMP messages. If the host is a
^^^^^^^^^ ^^^^^^ ^^^^^^^^^ ^^^^ ^^^^^^^^
router, routed periodically supplies copies of its routing tables to any
directly connected hosts and networks. It also advertises or solicits
default routes using Router Discovery ICMP messages.

ICMP 520? ICMP Router Advertisements are ICMP type 9. Again, if we
RTFM,
no_rdisc
disables the Internet Router Discovery Protocol.
Do you maybe just want to turn this off?
Another question might be, if you don't know what all of this stuff
is, do you really need to be running routed(8) at all?
