D-Link DES-3326S Layer 3 Switch
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.
