Question 87 - PCNSE discussion

The best way to minimize the BGP configuration and management overhead on on-prem network devices is to summarize BGP routes before advertising them. Route summarization is a technique that reduces the number of routes in a routing table by aggregating multiple routes into a single route with a less specific prefix. This reduces the size of routing updates and the memory and CPUusage of routers. Prisma Access supports route summarization for service connections and remotenetwork connections that use BGP routing1. You should not implement target service connection for traffic steering, as this is a feature that allows you to select a specific service connection for traffic from a remote network connection or a mobile user based on destination IP address orapplication. This does not affect the BGP configuration or management on on-prem networkdevices2. You should not implement hot potato routing, as this is a routing technique that selects the closest exit point to the destination network based on the number of hops or the lowest IGPmetric. This does not affect the BGP configuration or management on on-prem network devices3.You should not implement default routing, as this is a routing technique that uses a default route to forward packets to an unknown destination. This does not affect the BGP configuration ormanagement on on-prem network devices, and it may not provide optimal routing for Prisma Access traffic4.
