What is crypto ISAKMP identity address?

What is crypto ISAKMP identity address?

crypto isakmp identity (address | hostname) Command. crypto isakmp identity Command. Description. address. Sets the ISAKMP identity to the IP address of the interface that is used to communicate to the remote peer during ISAKMP negotiations.

What is crypto ISAKMP policy?

With ISAKMP keepalives enabled, the router sends Dead Peer Detection (DPD) messages at intervals between 10 and 3600 seconds. In the event that a response to a DPD is not received, the router then sends the DPD messages at a more aggressive rate — between 2 and 60 seconds.

What is crypto map VPN?

Crypto maps use traffic selection mechanism in form of access-list. In this case router will be interested to encrypt all traffic from 172.16. 1.0/24 subnet. The remote end will used access-list specifying the reverse “any to 172.16. 1.0/24” (or use dynamic crypto map!).

What is ISAKMP profile?

The Internet Security Association and Key Management Protocol (ISAKMP) profile is an enhancement to ISAKMP configurations. This modularity allows mapping different ISAKMP parameters to different IPsec tunnels, and mapping different IPsec tunnels to different VPN forwarding and routing (VRF) instances.

What port is ISAKMP?

ISAKMP can be implemented over any transport protocol. All implementations must include send and receive capability for ISAKMP using UDP on port 500.

What port is ESP?

Encapsulated Security Protocol (ESP): IP Protocol 50; UDP port 4500.

What is crypto map command?

A crypto map is a software configuration entity that performs two primary functions: Selects data flows that need security processing. Defines the policy for these flows and the crypto peer to which that traffic needs to go.

How do I create a VPN tunnel between two sites?

Step 2. Create the IPsec Tunnel on Location 1

  1. Log into the X-Series Firewall at Location 1.
  2. Go to the VPN > Site-to-Site VPN page.
  3. In the Site-to-Site IPSec Tunnels section, click Add.
  4. Enter a Name for the VPN tunnel.
  5. Configure the settings for Phase 1 and Phase 2.
  6. Specify the network settings:

What is crypto keyring?

The crypto keyring command, on the other hand, is used to create a repository of preshared keys. The keyring is used in the ISAKMP profile configuration mode. The ISAKMP profile successfully completes authentication of peers if the peer keys are defined in the keyring that is attached to this profile.

Is port 500 TCP or UDP?

Port 500 Details

Is Ike UDP or TCP?

IKE (Internet Key Exchange) (formerly known as ISAKMP – Internet Security Association and Key Management Protocol) is the most common protocol used to authenticate the VPN session. IKE is transported on 500/udp.

How to configure the crypto ISAKMP policy command?

To configure ISAKMP policies, in global configuration mode, use the crypto isakmp policy command with its various arguments. The syntax for ISAKMP policy commands is as follows: crypto isakmp policy priority attribute_name [attribute_value | integer] You must include the priority in each of the ISAKMP commands.

When do peer send their ISAKMP identity address?

When two peers use Internet Key Exchange (IKE) to establish IPSec associations, each peer sends its ISAKMP identity to the remote peer. It sends either its IP address or host name, depending on how it has its ISAKMP identity set.

How are crypto maps used to negotiate IPsec?

Crypto map names MY_CRYPTO_MAP has entry 100 using ISAKMP to negotiate IPsec. This crypto map entry should match traffic specified by access-list 100 and perform parameters defined in ISAKMP profile called MY_PROFILE. The way to protect traffic is defined in transform set MY_SET.

What’s the difference between Ike and ISAKMP in IPsec?

IKE, also called ISAKMP, is the negotiation protocol that lets two hosts agree on how to build an IPsec security association. ISAKMP separates negotiation into two phases: Phase 1 and Phase 2. Phase 1 creates the first tunnel, which protects la ter ISAKMP negotiation messages.
