we have 2 mikrotik routers, each connected to its own external peer, and both are connected with iBGP.
Here is some testing:
RT1:
Code: Select all
/ip route> print where dst-address in 8.8.8.0/24
Flags: X - disabled, A - active, D - dynamic, C - connect, S - static, r - rip, b - bgp, o - ospf, m - mme, B - blackhole, U - unreachable, P - prohibit
# DST-ADDRESS PREF-SRC GATEWAY DISTANCE

/tool traceroute 8.8.8.8

Another example, even more strange:
RT1:
Code: Select all
print where dst-address in 185.3.192.0/22
Flags: X - disabled, A - active, D - dynamic, C - connect, S - static, r - rip, b - bgp, o - ospf, m - mme, B - blackhole, U - unreachable, P - prohibit
