I have a group of sites using OSPF and PTP interfaces. I have an issue were I am unable to communicate to networks advertised and routed via OSPF at Site A to Site C and vice versa. Site B can reach any of the connected networks without issue. Site D connects to multiple other sites beyond it which also have no issues connecting to networks @ Site A and C. I have verified OSPF neighbor adjacencies are established and routes for each of the networks there. I have also checked CEF and the cached routes match the expected OSPF routes. Could this be a IOS bugor could it be a hardware issue?
