test_bgp_rr_ibgp_topo1.py: Testing IBGP with RR and no IGP

|

|

In a leaf/spine topology with only IBGP connections, where
|
||||
the same network is being redistributed at multiple points
|
||||
in the network ( say a redistribute connected at both leaf and spines )
|
||||
we end up in a state where zebra gets very confused.

|
||||
|
||||
Effectively we have ibgp routes recursing through ibgp routes
|
||||
and there is no metric to discern whom to listen to.
|
||||
|
||||
This draft:
|
||||
https://tools.ietf.org/html/draft-ietf-idr-bgp-optimal-route-reflection-19
|
||||
|
||||
appears to address this issue. From looking at both cisco and arista
|
||||
deployments they are handling this issue by having the route reflector
|
||||
prefer the localy learned routes over from their clients.
|
||||
|
||||
Add this topology, in a broken state, so that when we do fix this issue
|
||||
it is a simple matter of touching this topology up and re-adding it
|
||||
to the normal daily builds. I also wanted to add this topology
|
||||
since it is in a state of `doneness` and I wanted to move onto
|
||||
my normal day job without having to remember about this test.
|
||||
|
||||
This topology is not configured to be run as part of the normal
|
||||
topotests.
