I am currently studying for my CCNA exam and have been using a simulator to test out configurations. However I have run into a problem. I can't seem to get the configuration to work like the book says it should.
PC1----R1 ---- PC2
Now. I believe I have frame relay configured correctly, since all 3 routers can talk to each other.
I have R1 configured with the network command for all 4 interfaces it is using (2 sub interfaces)
R2 has the network command for its LAN, R3 has the network command for its LAN.
For some reason R1 is not advertising its LAN to the other two routers. I can however use "default-information originate" on Router 1 and this will then make it advertise its route to R2 and R3. From the way I read it, this command should not be necessary here. So why isn't R1 telling R2 and R3 about its two lan connections?
R1 will advertise R3 to R2 and vice versa. So i don't get why its not advertising PC1 and PC2.
