3.17 Disable Network Routing

Information

The network routing daemon, in.routed, manages network routing tables. If enabled, it periodically supplies copies of the system's routing tables to any directly connected hosts and networks and picks up routes supplied to it from other networks and hosts.

Rationale:

Routing Internet Protocol (RIP) is a legacy protocol with a number of security weaknesses including a lack of authentication, zoning, pruning, etc.

Solution

To enforce this setting and disable IPv4 routing, run the following command:

# routeadm -d ipv4-forwarding -d ipv4-routing

To enforce this setting and disable IPv6 routing, run the following command:

# routeadm -d ipv6-forwarding -d ipv6-routing

To apply these changes to the running system, run the following command:

# routeadm -u
