(Optional) Configuring Redundancy Control of IPSec Tunnels

Context

On a live network, to improve network reliability, a branch gateway connects to the headquarters using multiple links. The branch gateway needs to determine on which link an IPSec tunnel is established. You can associate IPSec with NQA so that the branch gateway controls IPSec tunnel setup or teardown according to the , which ensures that only one link is available at any time. The association implements redundancy control of the IPSec tunnel.

Prerequisites

  • If an NQA test instance is used to control IPSec tunnel setup or teardown, ensure that the NQA test instance has been created and configured. The device supports only association between IPSec and NQA of ICMP type. For details on how to configure an NAQ test instance of ICMP type, see Configuring an ICMP Test.
  • If an NQA group is used to control IPSec tunnel setup or teardown, ensure that the NQA group has been created and bound to an NQA test instance. The device supports only association between IPSec and NQA of ICMP type. For details on how to configure an NAQ group, see Configuring an ICMP Test Instance.
  • If a BFD session is used to control IPSec tunnel setup or teardown, ensure that the BFD session has been created and configured. For details on how to configure a BFD session, see Configuring Single-Hop BFD.
  • If a BFD group is used to control IPSec tunnel setup or teardown, ensure that the BFD group has been created and bound to a BFD session. For details on how to configure a BFD group, see Configuring BFD Group.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run ipsec policy policy-name seq-number isakmp

    The view of the ISAKMP IPSec policy is displayed.

  3. Run connect track { nqa admin-name test-name | nqa-group nqa-group-name } { up | down }

    The device is configured to control IPSec tunnel setup according to status.

    By default, the device is configured to not control IPSec tunnel setup according to status.

  4. Run disconnect track { nqa admin-name test-name | nqa-group nqa-group-name } { up | down }

    The device is configured to control IPSec tunnel teardown according to status.

    By default, the device is configured to not control IPSec tunnel teardown according to status.
