OSPF Network Configuration

OSPF Network Configuration

ospf

I have configured OSPF on all 4 routers displayed in the topology above.
However from the Computer (Router, configured with No IP Routing), I can ping only the interfaces of R1: g0/0 , g1/0,g2/0. I can not ping from computer to any interface on R2 or R3 or R4.

atlas_shudderedSr. Network EngineerCommented:
configure your interfaces as ospf point to point

R1 is not configured to announce .25.0/24   all other hosts will be unaware of it  configure statement or redistribute static subnets
R2 is configured routing for .23.0/24, not .24.0/24 as noted - correct this

after these three changes, run:

show ip ospf neighbors and confirm you have neighbors showing and convergence

You are correct. I have not advertised the network 192.168.15.0 ..after I have advertised, the issue is resolved.

Thank you
