Hi Fred,
Thanks for the suggestion. Let me check Border6 out.
Between, I talked to Huawei RR+ yesterday, it looks promising as well and
they can do inbound traffic load balancing based on route communities & AS
path prepending.
Let's see if I can get them to do a POC for us and update all. I asked them
few questions and wait for them to reply.
