  • replicate in our testing environment by removing one neighbour from bgp speaker and use ODL to advertize routes
  • instead of NEIGHBOR1 ---> BGP speaker ---> ODL, do NEIGHBOR1 ----> ODL ----> BGP speaker
  • verify that neighbor1 has all advertised routes

Needs to be fixed before Lithium goes out.

It's possible to simulate it if you configure app peer and give bgp peer peer-role Ebgp.
