different metric in RIPng and RIPv2

I find a confused issue when I test how RIPng is working. A very simple topology like that:

R1----R2--NetX

When I use rip version 2, metric for NetX in R1's routing table is 1. When I use RIPng, metric for NetX in R1's routing table is 2.

Why R1 has the different metric?  Why the metric(hop) is 2 in RIPng test when only one router(R2) is on the path.

Thanks a lot

Martin

Hi,

RIPng metrics are incremented inbound before being  added to the routing table/RIP database, while RIPv1 and RIPv2 metrics  are incremented outbound that is the cause of this discrepancy between the 2 protocols.
