I am testing a new design we are planning to implement and running into a strange issue. The network consists of 2 edge routers each connected to a different upstream peer and an iBGP connection between them. Everything works fine until I disable the iBGP connection between the 2 edge routers. After the hold time expires and the routers withdraw their iBGP advertisements, the ISP routers lose the eBGP routes sent by the edge routers. The ISP routers show 0 prefixes on the peer session with the edge router, but the edge router shows that it is still advertising the prefixes.A refresh on the ISP router side or resend on the edge side will restore the routes. Am I doing something wrong, or is this a bug? All routers are at 6.46.4.
