Hop Count-Based Forwarding for Branch Gateway Mode
Branch Gateways (BGWs) now account for hop count when making forwarding
decisions in BGW mode, consistent with the existing behavior in DC mode
introduced in 6.5.1.
In full-mesh BGW deployments a BGW can learn the same prefix from
multiple peer BGWs. Without hop count awareness, traffic could be forwarded
sub-optimally, bouncing between BGWs before reaching its final destination. With
this enhancement, BGWs prefer the lowest hop-count path, ensuring traffic takes
the most direct route to its destination. This improvement benefits customers
running full-mesh BGW topologies who prefer not to configure explicit
prefix-based path policies, or those operating in dynamic environments where
prefixes change frequently.
