Hello,
I was reading the OSPFv2 RFC, namely, from page 62:
The Area ID specified in the header must either:
(1) Match the Area ID of the receiving interface. In this
case, the packet has been sent over a single hop.
Therefore, the packet’s IP source address is required to
be on the same network as the receiving interface. This
can be verified by comparing the packet’s IP source
address to the interface’s IP address, after masking
both addresses with the interface mask. *This comparison*
* should not be performed on point-to-point networks*. On
point-to-point networks, the interface addresses of each
end of the link are assigned independently, if they are
assigned at all.
I have tried this on various Cisco routers and it doesn't work. It
complains about the interfaces being in a different network.
Is this an implementation flaw?
