What you logged there are probably DHCP packets and private use of RIP, not the AMPR-RIP.
Well, I do see a lot of those things here either...
Recently I again worked on the filters and found e.g.:
- router-sourced traffic with inner source address equal to the external IP (bad source
address selection)
- router sending some of the traffic outside of the tunnel (net-44 to net-44 traffic
unencapsulated)
the funny thing is that e.g. when pinging them it returns via the tunnel but when doing
BGP the
SYN ACKs from port 179 come outside the tunnel. when the sender had proper source
address filtering
at their ISP I would not see those packets at all.
- of course still a lot of traffic with inner source address in RFC1918 range
The first two above are blamed on "MikroTik VRF". I never use it, I always use
a manual implementation
using multiple routing tables, ip routing rules and maybe some mangle rules just as I am
used to do
on bare Linux, and I don't have those problems.
Another group swears by VRF and they always have issues.
As I believe MikroTik VRF is just an an automatic configuration of the mentioned features
and
it apparently does not work completely OK (and may need some help e.g. some extra mangle
rule).
I tried to get information on what really happens when you define a VRF, but I was unable
to
get answers.
