Hi everyone,
I have a router receiving it's routes via OSFP. On the router, I have set up a incoming filter to block 10.x.x.x addresses (not working)
In the routing table I see several 10.0.32.0/24, 10.0.46.0/24, 10.0.31.0/24, etc making it thru the incoming OSFP filter.
Here is the filter I am using:
chain=ospf-in prefix=10.0.0.0/8 invert-match=no action=discard
However, when I put a more specific route in for the filter prefix=10.0.32.0/24, it will indeed block that 10.0.32.0/24 block. This is good, as I know I'm not completely wrong in setting up an OSPF filter, but I have a large number of 10.x.x.x blocks that I would need to manually put filter rules in for, when ideally I would like to filter the entire 10.0.0.0/8 range. I've also tried 10.0.0.0/16, no luck.
I don't understand what is happening.
Thanks for your help.
