Which routing protocol excludes the subnet information from routing updates?
RIP VERSIONV1 can be seen to exclude subnet information from
routing updates, this is because ripv1 is a classful routing
protocol and does not support VSLM, this was corrected in RIPv2
where ripv2 does send out subnet mask's in the form of a prefix eg
/24 which is the subnet mask of 255.255.255.0 or a class c
address.
