Router Interface Commands
Router Interface Filter Commands
egress
Syntax egress
Context config>router>interface
Description
This command enables access to the context to configure egress network filter policies for the IP
interface. If an egress filter is not defined, no filtering is performed.
ingress
Syntax ingress
Context config>router>interface
Description
This command enables access to the context to configure ingress network filter policies for the IP
interface. If an ingress filter is not defined, no filtering is performed.
flowspec
Syntax [no] flowspec
Context config>router>interface>ingress
Description This command enables IPv4 flowspec filtering on a network IP interface. Filtering is based on all of
the IPv4 flowspec routes that have been received and accepted by the base router BGP instance.
Ingress IPv4 traffic on an interface can be filtered by both a user-defined IPv4 filter and flowspec.
Evaluation proceeds in this order:
1.user-defined IPv4 filter entries
2.flowspec-derived filter entries
3.user-defined IPv4 filter default-action
The no form of the command removes IPv4 flowspec filtering from the network IP interface.
Default
No network interfaces have IPv4 flowspec enabled.
flowspec-ipv6
Syntax [no] flowspec
Context config>router>interface>ingress
