Router 1 also has another router it's connected to but it's just a mirror of router 2, I'm not sure what I've done wrong, can someone provide some help, please excuse the ignorance I'm new to this.
Thanks in advance.

Hello
You have confirmed your using simulation software and the latest being GNS3 and you still dont obtain connectivity?
Now GNS3 by default uses encapsulation on its serial interfaces that requires nothing appended to it (clocking or,controller state), just the correct ip addressing and the very basic ospf1 config (below) and if this isnt working it has to be the software your using.
r1
int ser0/0/0
ip address 10.10.10.1 255.255.255.252
no shut
r2
nt ser0/0/0
ip address 10.10.10.2 255.255.255.252
no shut
both rtrs
router ospf 1
network 10.10.10.0 0.0.0.3 area 0
