- if the ixp port is connected to an intermediate switch on the member side, the ixp member router won't see the carrier state transition and will blackhole traffic on the member side - all other ixp members who peer with that router also won't see the carrier state and will leave bgp up, causing traffic to be blackholed on the remote side.
