In the example, the following configuration is applied:

•Router A (router ID A) has clients configured B, C, and D. Therefore it serves as the route reflector for these BGP routers.

•Routers B, C, and D all have Router A as a BGP non-client neighbor.

•Router D and Router B also have each other configured as BGP non-client neighbors.

In this case, in Cisco ANA, the following information is maintained by a VNE:

•Router B learns router ID D from interface 1.

•Router B learns router IDs A, C, and D from interface 2.

•Router C learns router IDs A, B, and D from interface 1.

•Router D learns router ID B from interface 2.

•Router D learns router IDs A, B, and C) from interface 1.

•Router A learns router ID D from interface 1.

•Router A learns router ID C from interface 2.

•Router A learns router ID B from interface 3.

In the Figure 8-2example, if a BGP connection is lost from Router A to Router B, the following occurs:

•Router A notifies both Routers C and D of the loss of router ID B.

•Router C removes the ID of Router B from its tables and completely loses connectivity to it, resulting in a Real Affected impact analysis.

•Router D loses the ID of Router B learned from interface 1, but it still has Router B’s ID that was learned through interface 2. Therefore, no impact analysis is performed.

If a BGP connection is lost from Router B to Router D, the following occurs:

•Router B does not notify Router A of its router ID loss, because Router A is configured in Router B’s tables as a non-client peer.

•Router D does not notify Router A of its router ID loss, because Router A is configured in Router D’s tables as a non-client peer.

•Router B notes that the ID of Router D is no longer learned through interface 1.
