Setting keepalive timers Optional.
Setting the NAT keepalive timer Optional.

Disabling next payload field checking Optional.
Configuring a name for the local security gateway
If the IKE negotiation peer uses the security gateway name as its ID to initiate IKE negotiation (that is, the
id-type name or id-type user-fqdn command is configured on the initiator), configure the ike local-name
command in system view or the local-name command in IKE peer view on the local device. If you
configure both commands, the name configured by in IKE peer view is used.
To configure a name for the local security gateway:
Step Command Remarks
1. Enter system view. system-view N/A
2. Configure a name for the
local security gateway.
ike local-name name
Optional.
By default, the device name is used as
the name of the local security gateway.
Configuring an IKE proposal
An IKE proposal defines a set of attributes describing how IKE negotiation should take place. You may
create multiple IKE proposals with different preferences. The preference of an IKE proposal is represented
by its sequence number, and the lower the sequence number, the higher the preference.
Two peers must have at least one matching IKE proposal for successful IKE negotiation. During IKE
negotiation, the initiator sends its IKE proposals to the peer, and the peer searches its own IKE proposals
for a match. The search starts from the one with the lowest sequence number and proceeds in the
ascending order of sequence number until a match is found or all the IKE proposals are found
mismatching. The matching IKE proposals will be used to establish the secure tunnel.
Two matching IKE proposals have the same encryption algorithm, authentication method, authentication
algorithm, and DH group. The SA lifetime will take the smaller one of the settings on the two sides.
By default, there is an IKE proposal, which has the lowest preference and uses the default encryption
algorithm, authentication method, authentication algorithm, DH group, and ISAKMP SA lifetime.
To configure an IKE proposal:
Step Command Remarks
1. Enter system view. system-view N/A
2. Create an IKE proposal
and enter its view.
ike proposal proposal-number N/A
