Redirecting a public IPv4 BGP FlowSpec route to an SRv6 TE Policy helps implement more accurate traffic filtering.
In traditional BGP FlowSpec-based traffic optimization, traffic transmitted over paths with the same source and destination nodes can be redirected to only one path, which does not achieve accurate traffic steering. With the function to redirect a public IPv4 BGP FlowSpec route to an SRv6 TE Policy, a device can redirect traffic transmitted over paths with the same source and destination nodes to different SRv6 TE Policies.
