Hot-standby HA with routing protocols

6

NOTE

Manual alteration of the cost or the metric of the routing protocols can affect the traffic forwarding
by the HA pair. For internal BGP (IBGP), you need to enable the compare-med-empty-aspath flag on
the upstream and downstream router for cost and MED to be considered for route selection. The
BGP RFC defines all vendor support.
