What problem?
R3 should have a metric of 3 should it not?
On your topology R2 has the route with a metric of 2, passes it to R3, now
R3 has the route with a metric of 3, hop count has increased by 1 hop, which
is correct.

Lee.

Subject: IPv6 RIP metric: strange calculation
Hi group,
Doing a simple IPv6 RIP lab on 3 routers:
f0/0-R1-s0/0------s0/0-R2-s0/1------s0/0-R3-f0/0
Suppose R1 f0/0 IPv6 address is Z.
I noticed the following:
R1 advertises Z with metric of 1: this is normal behaviour
R2 receives the route Z with metric of 1. "show ipv6 route" output shows
route Z with metric 2. R2 continues to send route Z metric 2 to R3 without
increasing the metric.
R3 has a route to Z with metric 3. It also sends the route out int f0/0
with
metric 3.
All my routers use c2600-is-mz.122-15.T16.bin. Is this the bug of the IOS ?
Has anyone got the same problem ?
Regards
Duongla
