How do i configure a lab to simulate a BGP routing protocol loop?
I want to see the effects on the routing table and then to experiment with different fixes.
Are there any examples around?
Below post by Petr should cover what you are looking for
The above is a typical eg: of what happens if the iBGP peering is done without considering the data plane/forwarding parth.
Though it doesn't quite happen in the real, you can also us "allow-as-in" or the "as-override" feature and you should be able to simulate this (Kinda cheap trick )
Many thanks, this will take a while to absorb.
I am also looking for an example where a route seems to be poisoned, deleted and then returns on a cyclic 30 second timer.
Sorry for being very broad but use a lot of summarizations, simulate flaps in short intervals (maybe with EEM scripts)
The idea is to think how the protocol does and fool it
