BLOCK

The BLOCK parameter prevents the network route received on the specified interface from being included in the RouteD routes table.

Consequently, the network is unknown and not forwarded to any other routers. Specify networks that you want to block by one of the following methods:

Network

A network that is specified as an IP address and a mask or as an IP address and a bit number. The bit number n indicates which bit in the 0 – 32 bits of the IP address (counting left to right beginning from 0) is the last bit of the network portion of the IP address. If the MASK and bit number are missing, a mask of 255.255.255.255 is used.

PRIVATE

The PRIVATE keyword refers to the sets of IP addresses that are designated for use by the Internet Assigned Number Authority (IANA) only within the private Internet. For more information, see RFC 1918, section 3.

• 10.0.0.0 to 10.255.255.255 (10/8 prefix) – 1 class A network.

• 172.16.0.0 to 172.31.255.255 (172.16/12 prefix) – 16 contiguous class B networks.

• 192.168.0.0 to 192.168.255.255 (192.168/16 prefix) – 256 contiguous class C networks.

When the RouteD server tries to send a route, it processes multiple forward parameters in the supplied order. The first forward parameter that allows the system to send the route over the specified interface ends the processing. The default is to forward.
