Configuring Global IKEv2 Options
Configure global IKEv2 options that are independent of peers. All the global IKE commands start with prefix ikev2.
IKEv2 Option Description
ikev2 retry-count
<number>
Maximum number of attempts to retransmit a message. Default 5.
NOTE
Range is 1 to 10.
ikev2 exchange-max-time
<seconds>
Maximum setup time for an exchange, in seconds. Default 30 seconds.
NOTE
Range is 0 to 300 seconds.
ikev2 retransmit-interval
<time>
IKEv2 message resend delay, in seconds. This is the time that the IKEv2 task is to wait before attempting the first
resend of a packet. Default is 5 seconds. Retransmit interval will increase exponentially.
NOTE
Range is 1 to 60 seconds.
ikev2 http-url-cert Enables the HTTP CERT support. HTTP CERT is disabled by default. If enabled then
HTTP_CERT_LOOKUP_SUPPORTED should be send along with the CERT_REQ payload. Default is disabled.
ikev2 cookie-challenge
<number
>
Enabled an IKEv2 cookie challenge only when the number of half-open IKE SAs crosses the configured number.
Default is disabled.
NOTE
Range is 1 to 2000 (max number of SA supported).
ikev2 limit { max-in-negotiation-
sa limit | max - sa limit }
max-in-negotiation-sa limit — Limits the total number of in negotiation IKEv2 SAs on the node. Default is 256.
max-sa limit — Limits the total number of IKEv2 SAs on the LP. Default is 256.
NOTE
For both limits the range is 1 to 256 (max SAs supported).
ikev2 Allow duplicate ike-sa For a given source/destination and IKE Profile, if multiple IKE SA can be created. This will be applicable only for
incoming IKE session. Default is disabled. This will be used for inter-op with other vendors.
NOTE
Not supported for NI R05.8.00 release.
ikev2 fragmentation [ mtu-size ] (Optional) To support fragmentation of IKEv2 message into small parts to avoid UDP level fragmentation. Default
it is disabled. It is at the global level because the routing can change, and we should be able to estimate what will
be the maximum size for the router. Range should be between 68 to 1500.
