When I redistribute an external route from OSPF into RIP, the route loses its tag value when I check the RIP router's routing table. So, in order for the specific tag to exist in RIP, I have to specifically reassign the tag value in the redistribution process from OSPF to RIP. Please shed some light on why the tag value is lost in the redistribution process between OSPF and RIP.
it is the size of the field that matters not the value inside.
Think of if from a programming point of view in a language like C that has the types of variables.
For this reason I think the tag is not transported into RIP.
Hope to help
