Crypto Template Configuration Mode Commands

The Crypto Template Configuration Mode is used to configure an IKEv2 IPSec policy. It includes most of the IPSec parameters and IKEv2 dynamic parameters for cryptographic and authentication algorithms. A security gateway service will not function without a configured crypto template. Only one crypto template can be configured per service.

Mode

Exec > Global Configuration > Context Configuration > Crypto Template Configuration

configure > context context_name > crypto template template_name ikev2-dynamic

Entering the above command sequence results in the following prompt:

[context_name]host_name(crf-crypto-tmp1-ikev2-tunnel)#

control-dont-fragment

Controls the Don't Fragment (DF) bit in the outer IP header of the IPSec tunnel data packet.

Product

All IPSec-related services

Privilege

Security Administrator

Syntax

control-dont-fragment { clear-bit | copy-bit | set-bit } 

clear-bit

Clears the DF bit from the outer IP header (sets it to 0).

copy-bit

Copies the DF bit from the inner IP header to the outer IP header. This is the default action.

set-bit

Sets the DF bit in the outer IP header (sets it to 1).

Usage Guidelines

A packet is encapsulated in IPSec headers at both ends. The new packet can copy the DF bit from the original unencapsulated packet into the outer IP header, or it can set the DF bit if there is not one in the original packet. It can also clear a DF bit that it does not need.

Example

The following command sets the DF bit in the outer IP header:
control-dont-fragment set-bit 

dns-handling

Adds a custom option to define the ways a DNS address is returned based on proscribed circumstances described below.

Product

PDIF

Privilege

Security Administrator

Syntax

[ default ] dns-handling { custom | normal } 

default

Configures the default condition as normal . By default, PDIF always returns the DNS address in the config payload in the second authentication phase if one is received from either the configuration or the HA.

dns-handling custom

Configures the PDIF to behave as described in the Usage section below.

dns-handling normal

This is the default action. The service always returns the DNS address in the config payload in the second authentication phase if one is received from either the configuration or the HA.

Usage Guidelines

During IKEv2 session setup, MS may or may not include INTERNAL_IP4_DNS in the Config Payload (CP). PDIF may obtain one or more DNS addresses for the subscriber in DNS NVSE from a proxy-MIP Registration Reply message. If Multiple Authentication is used, these DNS addresses may be also received in Diameter AVPs during the first authentication phase, or in RADIUS attributes in the Access Accept messages during the second authentication phase.

In normal mode, by default PDIF always returns the DNS address in the config payload in the second authentication phase if one is received from either the configuration or the HA.

In custom mode, depending on the number of INTERNAL_IP4_DNS, PDIF supports the following behaviors:
  • If MS includes no INTERNAL_IP4_DNS in Config Payload: PDIF does not return any INTERNAL_IP4_DNS option to MS, whether or not PDIF has received one in DNS NVSE from HA or from local configurations.

  • If MS requests one or more INTERNAL_IP4_DNS(s) in Config Payload, and if P-MIP NVSE doesn't contain any DNS address or DNS address not present in any config, PDIF omits INTERNAL_IP4_DNS option to MS in the Config Payload.

  • And if P-MIP NVSE includes one DNS address (a.a.a.a / 0.0.0.0), then PDIF sends one INTERNAL_IP4_DNS option in Config Payload back to the MS.

  • If the Primary DNS is a.a.a.a and the Secondary DNS is 0.0.0.0, then a.a.a.a is returned (only one instance of DNS attribute present in the config payload).

  • If the Primary DNS is 0.0.0.0 and the Secondary DNS is a.a.a.a, then a.a.a.a is returned (only one instance of DNS attribute present in the config payload). PDIF does not take 0.0.0.0 as a valid DNS address that can be assigned to the MS.

  • And if P-MIP NVSE includes two DNS addresses (a.a.a.a and b.b.b.b) or configurations exists for these two addresses, then PDIF sends two INTERNAL_IP4_DNSs in the CP for the MS (typically known as primary and secondary DNS addresses).

Example

The following configuration applies the custom dns-handling mode:
dns-handling custom 

dos cookie-challenge notify-payload

Configure the cookie challenge parameters for IKEv2 INFO Exchange notify payloads for the given crypto template.

Product

All IPSec-related services

Privilege

Security Administrator

Syntax

dos cookie-challenge notify-payload [ half-open-sess-count start integer stop integer] 
[ default | no ] cookie-challenge detect-dos-attack 

default

Default is to disabled condition.

no

Prevents Denial of Service cookie transmission. This is the default condition.

half-open-sess-count start integer stop integer

The half-open-sess-count is the number of half-open sessions per IPSec manager.

A session is considered half-open if a PDIF has responded to an IKEv2 INIT Request with an IKEv2 INIT Response, but no further message was received on that particular IKE SA.
  • start integer : Starts when the current half-open-sess-count exceeds the start count. The start count is an integer from 0 to 100000.

  • stop integer : Stops when the current half-open-sess-count drops below the stop count. The stop count number is an integer from 0 to 100000. It is always less than or equal to the start count number


Important


The start count value 0 is a special case whereby this feature is always enabled. In this event, both start and stop must be 0.


Usage Guidelines

This feature (which is disabled by default) helps prevent malicious Denial of Service attacks against the server by sending a challenge cookie. If the response from the sender does not incorporate the expected cookie data, the packets are dropped.

Example

The following example configures the cookie challenge to begin when the half-open-sess-count reaches 50000 and stops when it drops below 20000:
dos cookie-challenge notify-payload half-open-sess-count start 50000 stop 20000

payload name

Specifies the name of a new or existing crypto template payload as an alphanumeric string of 1 through 127 characters.

match { any | ipv4 | ipv6 }

Filters IPSec Child Security Association creation requests for subscriber calls by applying the following options:
  • any : Configures this payload to be applicable to IPSec Child Security Association requests for IPv4 and/or IPv6.
  • ipv4 : Configures this payload to be applicable to IPSec Child Security Association requests for IPv4 only.
  • ipv6 : Configures this payload to be applicable to IPSec Child Security Association requests for IPv6 only.

Usage Guidelines

Use this command to create a new or enter an existing crypto template payload. The payload mechanism is a means of associating parameters for the Security Association (SA) being negotiated.

Two payloads are required: one each for MIP and IKEv2. The first payload is used for establishing the initial Child SA Tunnel Inner Address (TIA) which will be torn down. The second payload is used for establishing the remaining Child SAs. Note that if there is no second payload defined with home-address as the ip-address-allocation then no MIP call can be established, just a Simple IP call.

Currently, the only available match is for ChildSA, although other matches are planned for future releases. Omitting the second match parameter for either IPv4 or IPv6 will make the payload applicable to all IP address pools.

Crypto Template Payload Configuration Mode commands are defined in the Crypto Template IKEv2-Dynamic Payload Configuration Mode Commands chapter.
