What is the lifetime of IPsec phase 1 and 2?

Cisco Meraki products, by default, use a lifetime of 8 hours (28800 seconds) for both IKE phase 1 and IKE phase 2. When there is a mismatch, the most common result is that the VPN stops functioning when one site's lifetime expires.

What is lifetime in IPsec VPN?

The time-based global IPsec SA lifetime is 3600 seconds, and the traffic-based global lifetime is 1843200 kilobytes.

What is the lifetime best practice for IPsec phase 2?

We can recommend a lifetime of 86400 seconds for phase 1 and 3600 seconds for phase 2.

What is the difference between IPsec phase 1 and phase 2?

Phase 1 Security Associations are used to protect IKE messages that are exchanged between two IKE peers, or security endpoints. Phase 2 Security Associations are used to protect IP traffic, as specified by the security policy for a specific type of traffic, between two data endpoints.

What is Phase 2 lifetime?

The default lifetime for IKE Phase 2 is 3600 seconds, or 1 hour.

What is the maximum lifetime of IPsec?

Valid values are between 60 sec and 86400 sec (1 day). The default value is 3600 seconds.

What is the lifetime of IPsec IKEv2?

By default, the IKEv2 SA lifetime is 86400 seconds.

What is the default lifetime of ASA Phase 2?

The Phase II lifetime, by contrast, is considerably shorter with a default of 3600 seconds (1 hour) on the Cisco IOS routers and 28800 seconds (8 hours) on the ASA, PIX and VPN concentrator.

What is key lifetime?

The lifetime of a key indicates where it is stored and which application and system actions will create and destroy it. Lifetime values are composed from: A persistence level, which indicates what device management actions can cause it to be destroyed.

What happens in Phase 2 of IPsec VPN?

The purpose of Phase 2 negotiations is for the two peers to agree on a set of parameters that define what traffic can go through the VPN, and how to encrypt and authenticate the traffic. This agreement is called a Security Association.

Is IPsec VPN layer 2 or 3?

More specifically, IPsec is a group of protocols that are used together to set up secure connections between devices at layer 3 of the OSI model (the network layer).

What happens in Phase 1 of IPsec VPN?

In IKE phase 1, two peers will negotiate about the encryption, authentication, hashing and other protocols that they want to use and some other parameters that are required. In this phase, an ISAKMP (Internet Security Association and Key Management Protocol) session is established.

What is the difference between IKE v1 and v2?

IKEv2 uses four messages; IKEv1 uses either six messages (in the main mode) or three messages (in aggressive mode). IKEv2 has Built-in NAT-T functionality which improves compatibility between vendors. IKEv2 supports EAP authentication. IKEv2 has the Keep Alive option enabled as default.

Does IKEv2 have two phases?

Both IKEv1 and IKEv2 protocols operate in two phases. The differences between the two protocols include: The first phase in IKEv2 is IKE_SA, consisting of the message pair IKE_SA_INIT. The attributes of the IKE_SA phase are defined in the Key Exchange Policy.

How do I check my IPsec Phase 1 status?

To view status information about active IPsec tunnels, use the show ipsec tunnel command. This command prints status output for all IPsec tunnels, and it also supports printing tunnel information individually by providing the tunnel ID.

What is the default ASA Phase 2 lifetime?

The default value equals 86400 seconds (1 day). This is a common value and also the default on our Cisco ASA Firewall. keylife=60m: This is the IKE Phase2 (IPsec) lifetime. Default strongSwan value is 60 minutes which is the same as our Cisco ASA Firewall's 3600 seconds (1 hour).

What is the default key lifetime for Cisco IPsec?

IPSec SA has 2 lifetime values; time in seconds (default 28,800) and data/traffic volume in kilobytes (default 4,608,000).

What is the lifetime of IKEv2 main mode SA?

IKE Main Mode SA lifetime is fixed at 28,800 seconds on the Azure VPN gateways.

What is the lifetime of crypto IKEv2?

Command Default

The default lifetime period for an IKEv2 SA is 43200 minutes (30 days).

What is the command to check IPSec phase 2?

To view the IPSec data that SAs built in IKE Phase 2, use the show crypto ipsec sa command.

In which 2 modes does Asa work How are the 2 modes different?

The appliance connects the same Layer 3 network subnet on its inside and outside ports, but each interface of the firewall resides in a different Layer 2 Vlan. The Cisco ASA firewall can operate both in Routed Firewall Mode (default mode) or in Transparent Firewall Mode.

What happens when IPsec lifetime expires?

The IPSec SA lifetime can be by time or traffic volume. If the traffic-based SA lifetime expires, the tunnel is disconnected.

What is the default Isakmp lifetime?

Phase I lifetime on Cisco IOS routers is managed by the global ISAKMP Policy. However this is not a mandatory field, if you do not enter a value, the router will default to 86400 seconds.

What is the default security association lifetime?

The security association lifetime in a crypto map entry overrides the global security association lifetime value. Specifies the number of seconds a security association will live before it expires. The default is 3,600 seconds (one hour).
