4 routers, all connected in this way:
A <--> B <--> C <--> D
And having routing-test enabled on routers B and C (which are in the middle) and filtering all unwanted networks (distinct than 10.0.0.0/8-27) like this:
Routes distinct than 10.0.0.0/8 with prefix 28-32 doesn't appear on routers B and C, so looks like the filters are working OK, but....
Code: Select all
/ routing filter add chain=ospf-out prefix=10.0.0.0/8 prefix-length=8-27 invert-match=no \ action=accept comment="" disabled=no add chain=ospf-out invert-match=no action=discard comment="" disabled=no
Having a local route on router A like 192.168..0.0/24, which is correctly filtered on routers B and C, do appear again on router D. How it could be possible? Is there any way to avoid this? (there is no direct connection between router A and D, and what is wanted to achieve is avoid routes trespassing the filters)
Tested on 2.9.30 and 2.9.38
