BGP should add only the best routes to the routing table ???
I assembled a simple stand (tested on different versions of 6.x)
A ring of 4 routers connected in series between neighbors.(see attach eBGP_test1-4.png )
BGP was raised on routers and the 1 loopback (10.230.255.x) address was announced
On different routers of this network there is a different number of inactive (blue routes).
I thought that bgp will choose only the best and will not add the rest.
Or If adds all possible paths to the table. then all routers should have the same number of routes.
(see attach Routes01.PNG )
Trying to make filters:
prepend
weight
MED
doesn't really affect the picture.
the only thing i found out
the smallest ID router has the fewest blue routes.
(see attach Routes2-RouterID.PNG )
(config files attached))
The question is, I don’t understand something, or does BGP on Mikrotik have hidden mechanisms for calculating which route to add in blue and which to discard.
I want to have only black routes on all routers (30 routers in a fell mesh topology in the future)
