Community
This parameter specifies the community name used by this interface for
authentication purposes as specified in RFC 1723 section 3.1. It is valid for
interfaces with a SUPPLY value of RIP2. The
rip_community_name
is a character
string of 1 to 16 characters in length.
If you specify the community option, then the system indicates that authentication is
needed for this interface. The community name that is specified with the community
option must match the community name sent in all RIP2 message blocks for this
interface. If you do not specify the community option, then the system does not
indicate any authentication for this interface.
Additional Parameters
You can also encounter the following RIP_INTERFACE parameters:
v BLOCK
v FORWARD
v FORWARD.COND
v NOFORWARD
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 the0–nbits of the
IP address (counting left to right) is the last bit of the network portion of the IP
address. If the MASK and bit number are missing, the system calculates a
network by using the subnet mask of the interface specified through the
ADDTCPIFC CL command.
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
private
internets
. For more information, see RFC 1918, section 3.
v 10.0.0.0 to 10.255.255.255 (10/8 prefix) 1 class A network.
v 172.16.0.0 to 172.31.255.255 (172.16/12 prefix) 16 contiguous class B
networks.
v 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
not to forward.
