Rip Interface Settings - D-Link DES-3350SR User Manual

RIP Command Codes
The field VERSION contains the protocol version number (1 in this case), and is used by the receiver to verify which version of
RIP the packet was sent.
RIP 1 Message
RIP is not limited to TCP/IP. Its address format can support up to 14 octets (when using IP, the remaining 10 octets must be
zeros). Other network protocol suites can be specified in the Family of Source Network field (IP has a value of 2). This will
determine how the address field is interpreted. RIP specifies that the IP address, 0.0.0.0, denotes a default route. The distances,
measured in router hops are entered in the Distance to Source Network, and Distance to Destination Network fields.
RIP 1 Route Interpretation
RIP was designed to be used with classed address schemes, and does not include an explicit subnet mask. An extension to version
1 does allow routers to exchange subnetted addresses, but only if the subnet mask used by the network is the same as the subnet
mask used by the address. This means the RIP version 1 cannot be used to propagate classless addresses. Routers running RIP
version 1 must send different update messages for each IP interface to which it is connected. Interfaces that use the same subnet
mask as the router's network can contain subnetted routes, other interfaces cannot. The router will then advertise only a single
route to the network.
RIP Version 2 Extensions
RIP version 2 includes an explicit subnet mask entry, so RIP version 2 can be used to propagate variable length subnet addresses or
CIDR classless addresses. RIP version 2 also adds an explicit next hop entry, which speeds convergence and helps prevent the
formation of routing loops.
RIP2 Message Format
The message format used with RIP2 is an extension of the RIP1 format. RIP version 2 also adds a 16-bit route tag that is retained
and sent with router updates. It can be used to identify the origin of the route. Because the version number in RIP2 occupies the
same octet as in RIP1, both versions of the protocols can be used on a given router simultaneously without interference.

RIP Interface Settings

RIP settings are configured for each IP interface on the Switch. Click the RIP Interface Settings link in the RIP folder. The menu
appears in table form listing settings for IP interfaces currently on the Switch. To configure RIP settings for an individual interface,
click on the hyperlinked Interface Name. To view the next page of RIP Interface Settings, click the Next button.
Click the hyperlinked name of the interface you want to set up for RIP, which will give access to the following menu:
