Configure ACL 110 identifying the traffic from the LAN on R Now configure reciprocating parameters on R3. R1(config-if)# crypto map VPN-MAP Part 3: Configure IPsec Parameters on R Step 1: Configure router R3 to support a site-to-site VPN with R1.
R1(config-crypto-map)# exit Step 5: Configure the crypto map on the outgoing interface.įinally, bind the VPN-MAP crypto map to the outgoing Serial 0/0/0 interface.

MAP that binds all of the Phase 2 parameters together. Step 4: Configure the ISAKMP Phase 2 properties on R1.Ĭreate the transform-set VPN-SET to use esp-3des and esp-sha-hmac. R1(config)# crypto isakmp key cisco address 10.2. R1(config-isakmp)# authentication pre-share Therefore only the encryption, key exchange method, and DH method must be configured. Default values do not have to be configured ISAKMP Phase 1 table for the specific parameters to configure. Step 3: Configure the ISAKMP Phase 1 properties on R1.Ĭonfigure the crypto ISAKMP policy 10 properties on R1 along with the shared crypto key cisco.
The Security Technology Package license must be enabled to complete this activity. Part 1: Enable Security Features Step 1: Activate securityk9 module. IPsec acts at the network layer, protecting and authenticating IP packets between participating IPsec devices IPsec provides secure transmission of sensitive information over unprotected networks such as the Internet. The IPsec VPN traffic will pass through another router that has no knowledge of the VPN. In this activity, you will configure two routers to support a site-to-site IPsec VPN for traffic flowing from their SA Establishment ipsec-isakmp ipsec-isakmp Objectives Other parameters need to be explicitly configured.

The issue will be corrected in the upcoming Cisco Packet Tracer 7.2.1 build 222. The Cisco Netacad credentials are required at each application startup.Ĭisco Packet Tracer 7.2.1 might consistently crashing when configuring interfaces or when deleting links.The following Cisco Packet Tracer 7.2 bugs are fixed in Cisco Packet Tracer 7.2.1 : There is no limit on the number of machines that an account can be logged into Logging in removes all usage restrictions. Otherwise, Cisco Packet Tracer limits the number of times that files can be saved to ten times. However, new files created with Cisco Packet Tracer 7.2.1 can't be used in previous versions.Ĭisco Packet Tracer 7.2.1 requires a valid Cisco Networking Academy login for unrestricted use. All activities provided in the Cisco CCNA Routing & Switching, CCNA Discovery, CCNA Exploration, CCNA Security, and IT Essentials curricula are compatible with Packet Tracer 7.2.1. Ĭisco Packet Tracer 7.2.1 supports activities files (PKT / PKA) created with previous Packet Tracer 7.1 7.0, 6.3, 6.2, 6.1.1, 6.0.1 and 5.X. Manual installation of libpng12 is required to make Cisco Packet Tracer 7.2.1 work on Ubuntu 18.04.
Cisco Packet Tracer 7.2.1 is officially supported on Microsoft Windows 7,Windows 8.1, Windows 10, Ubuntu 14.04 LTS, and MacOS.Ĭisco Packet Tracer 7.2.1 is not officially supported on Ubuntu 18.04.
