undo ipsec { ipv6-policy | policy } policy-name local-address
Default
No IPsec policy is bound to a source interface.

Parameters
ipv6-policy: Specifies an IPv6 IPsec policy.
policy: Specifies an IPv4 IPsec policy.
policy-name: Specifies an IPsec policy name, a case-insensitive string of 1 to 63 characters.
local-address interface-type interface-number: Specifies the shared source interface by its type and
number.
Usage guidelines
For high availability, two interfaces can operate in backup or load sharing mode. After an IPsec policy
is applied to the two interfaces, they negotiate with their peers to establish IPsec SAs separately.
When one interface fails and a link failover occurs, the other interface needs to take some time to
renegotiate SAs, resulting in service interruption.
To solve these problems, bind a source interface to an IPsec policy and apply the policy to both
interfaces. This enables the two physical interfaces to use the same source interface to negotiate
IPsec SAs. As long as the source interface is up, the negotiated IPsec SAs will not be removed and
will keep working, regardless of link failover.
After an IPsec policy is applied to a service interface and IPsec SAs have been established, if you
bind the IPsec policy to a source interface, the existing IPsec SAs are deleted.
Only an IKE-based IPsec policy can be bound to a source interface.
An IPsec policy can be bound to only one source interface. If you execute this command multiple
times, the most recent configuration takes effect.
A source interface can be bound to multiple IPsec policies.
As a best practice, use a stable interface, such as a Loopback interface, as a source interface.
Examples
# Bind the IPsec policy map to source interface Loopback 11.
<Sysname> system-view
[Sysname] ipsec policy map local-address loopback 11
