RIPv1 vs RIPv2 Part II

rip weirdness

R1---FR---R2----2.0.0.0/8
| ----R3----|

R1-R2 is 12.0.0.0/8
R1-R3 is 13.0.0.0/8
R2-R3 is 23.0.0.0/8

RIP (default send v1, receive v1,v2) everywhere

R1's route table:

R1#show ip route | begin Gateway
Gateway of last resort is not set

1.0.0.0/16 is subnetted, 1 subnets
C 1.0.0.0 is directly connected, FastEthernet0/0
R 2.0.0.0/8 [120/1] via 13.0.0.3, 00:00:00, Serial1/1
[120/1] via 12.0.0.2, 00:00:00, Serial1/0
R 23.0.0.0/8 [120/1] via 13.0.0.3, 00:00:00, Serial1/1
[120/1] via 12.0.0.2, 00:00:00, Serial1/0
R 10.0.0.0/8 [120/1] via 13.0.0.3, 00:00:00, Serial1/1
[120/1] via 12.0.0.2, 00:00:00, Serial1/0
C 12.0.0.0/8 is directly connected, Serial1/0
C 13.0.0.0/8 is directly connected, Serial1/1
R1#

How could R1 have two equal routes to 2.0.0.0/8?

It should be 1 hop through R2
It should be 2 hops through R3

right?

What do you think?

Well let's do version 2 with no auto-summary:

R1#show ip route | begin Gateway
Gateway of last resort is not set

1.0.0.0/16 is subnetted, 1 subnets
C 1.0.0.0 is directly connected, FastEthernet0/0
R 2.0.0.0/8 [120/1] via 12.0.0.2, 00:00:00, Serial1/0
R 23.0.0.0/8 [120/1] via 13.0.0.3, 00:00:00, Serial1/1
[120/1] via 12.0.0.2, 00:00:00, Serial1/0
10.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
R 10.3.0.0/16 [120/1] via 13.0.0.3, 00:00:00, Serial1/1
R 10.0.0.0/8 is possibly down,
routing via 12.0.0.2, Serial1/0
C 12.0.0.0/8 is directly connected, Serial1/0
C 13.0.0.0/8 is directly connected, Serial1/1

What is really going on with RIP version 1? I have no idea...if you do, please let me know.
