Hello guys, This is obviously a noob question but here goes: We want to link our openstack cloud with the rest of the network with two separate external physical routers, for redundancy. These will also be the BGP peers declared in openstack for advertising internal routes. We could do VRRP and have a shared IP between the two external routers but I understand that if we make a bgp adjacency with a VIP between the two external routers, when this will move from one router to the other in case of failure, there will be a period of outage on the BGP. So in order to avoid that, in openstack we were thinking to have two external provider network vlans, one for each external router, which will handle connectivity with the exterior. What would be the best network design to link the tenant networks to these two networks in a HA mode? Where would be best place to do the “smart” routing to direct the traffic one way or the other. Or is there a more elegant solution? Thank you and sorry if the question is too basic or too general, hopefully if someone used this design can share their experience.
