BGP FlowSpec: IPv6

This feature extends IPv6 support is extended to the BGP flow specification which enables propagation of traffic flow specification rules for IPv6 and IPv6 VPN. The BGP flow specification automates coordination of traffic filtering rules in order to mitigate distributed denial-of-service attacks. In earlier Junos OS releases, flow-specific rules were propagated for IPv4 over BGP as network layer reachability information.

To enable the BGP flow specification for IPv6, include the flow statement at the [edit routing-options] hierarchy level for global configuration or at the [edit routing-instances routing-instance-name routing-options] hierarchy level for instance-level configuration.
