What is NAT WHAT IS BGP METRIC

Question

Accepted Answer

NAT is a technique used to map private IP addresses to public IP addresses for communication over the internet.

NAT stands for Network Address Translation.
It is used to conserve public IP addresses and provide security by hiding private IP addresses.
There are three types of NAT: Static NAT, Dynamic NAT, and PAT.
Static NAT maps a single private IP address to a single public IP address.
Dynamic NAT maps multiple private IP addresses to a pool of public IP addresses.
PAT (Port Address Translation) maps multiple private IP addresses to a single public IP address using different port numbers.
BGP Metric is a value used to determine the best path for BGP traffic.
It is used to measure the distance between two BGP routers.
The lower the metric, the better the path.
BGP Metric is calculated based on factors such as bandwidth, delay, reliability, and path length.
