ccna book in hindi.The cryptographic mapping entry created for JPSec combines the configuration parameters required for IPSec SA, including the following parameters.which flows to protect using a single encrypted ACL.The granularity of flows protected by a set of SAs.who the remote IPSec peer is, which determines where the IPSec-protected traffic is sent.The local address used for IPSec traffic (optional).Which type of IPSec security is applied to this traffic (select from a list containing one or more transformation sets); The key management method.SA survival period.Encryption mapping entries with the same encryption mapping name but different mapping order numbers are grouped into a single encryption mapping set.Only one encryption mapping can be set on an interface. The encryption mapping set can contain a collection of Cisco Encryption Technology (CET) and IPSec using IKE. Multiple interfaces can share the same set of encryption mappings if the same policy is applied to multiple interfaces. If multiple cryptographic mapping entries are created for a given interface, they are ranked using the sequential number (seq-m) of each mapping entry. The smaller the order number, the higher the priority. For interfaces where an encrypted mapping set exists, the higher priority mapping entry is used first to evaluate the traffic.Multiple encrypted mapping entries are created for a given interface if any of the following conditions hold.
