3 routers, no switches, and I want to telnet to any/all of them from any router

Ok I am doing some labs and the tasks calls for connecting 3 routers together (no switches) with both Serial connections and Fastethernet crossover connections. The fastether connections have Rip ver 2 and no auto-summary setup.

Here is my setup is as follows:

Router1:

Int s 2/0= 172.16.1.1/30 (Serial from Router 1 to router 2)
Int s 3/0= 172.16.1.9/30 (Serial from Router 1 to router 3)
Int F 0/0 = 192.168.1.1/24 (From Router 1 to router 2)
Int F 1/0 = 192.168.3.1/24 (From Router 1 to router 3)

Router2:

Int s 2/0=172.16.1.2/30 (Serial from Router 2 to router 1)
Int s 3/0=172.16.1.5/30 (Serial from Router 2 to router 3)
Int F 0/0=192.168.1.2/24 (From Router 2 to router 1)
Int F 1/0=192.168.2.1/24 (From Router 2 to router 3)

Router3:

Int s 2/0=172.16.1.6/30 (Serial from Router 3 to router 2)
Int s 3/0=172.16.1.10/30 (Serial from Router 3 to router1)
Int F 0/0=192.168.3.2 (From Router 3 to router 1)
Int F 1/0=192.168.2.2 (From Router 3 to router 2)

I have checked all statuses. All are up and up. My question is....How can I ping and then ultimately telnet to each of the routers in this configuration? There are no switches given in this lab scenario. Again I do have Rip v2 setup, but that is on the fastethernet connections. I thought about changing the encapsulation to ppp and then giving a username and password under that scheme, but I am not sure. Any help is appreciated.

Ok, you SAY you have RIP setup. The real question is: is it setup correctly? A copy and paste of your routing tables would go a long way in us helping you. Or at least your RIP configurations.

rip is setup on the fastethernet sides only and are as follows on each router

router rip
version 2
network 192.168.1.0
network 192.168.2.0
network 192.168.3.0
no auto-summary

Can you ping across all three routers? Ok, now do you have a local user defined? Configured your vty line/s for local login?

Get your pings going..then

username admin priv 15 secret cisco123

line vty 0 4
login local
transport input telnet

Now try using the local admin credential

I didn't do a login local....I did the following:

line vty 0 4 password cisco123 (your password for easier translation)
login

enable secret cisco456

I didn't put in transport input telnet...but I tried to do so after reading your post, but all of that didn't work. What I failed to do, and correct me if I am wrong is I did not include the 172.16.1.0 into the rip setup. Once I placed network 172.16.1.0 no auto-summary I was able to ping. Dang, how could I have missed that???

Thanks for the help and sorry for MY confusion.
