Configuring static route-based traffic steering
Restrictions and guidelines
After you configure this feature on a public IP over SRv6 network, execute the route-replicate command in public instance IPv4/IPv6 address family view to replicate the routes of the specified
VPN instance to the public network. The public network then can use the VPN routes to forward user traffic.
Procedure
1. Enter system view. system-view
2. Configure static route recursion to an SRv6 TE policy:
Configure IPv4 static route recursion to an SRv6 TE policy:
Public network: ip route-static dest-address { mask-length | mask } srv6-policy
{ color color-value end-point ipv6 ipv6-address | name policy-name }
[ sid sid ] [ preference preference ] [ tag tag-value ] [ description text ]
VPN: ip route-static vpn-instance s-vpn-instance-name dest-address
{ mask-length | mask } srv6-policy { color color-value end-point
ipv6 ipv6-address | name policy-name } [ sid sid ] [ preference preference ] [ tag tag-value ] [ description text ]
By default, no IPv4 static route is configured.

Reference .
Configure IPv6 static route recursion to an SRv6 TE policy:
Public network: ipv6 route-static ipv6-address prefix-length srv6-policy { color color-value end-point ipv6 ipv6-address | name policy-name } [ sid sid ] [ preference preference ] [ tag tag-value ] [ description text ]
VPN:
ipv6 route-static vpn-instance s-vpn-instance-name ipv6-address
prefix-length srv6-policy { color color-value end-point ipv6 ipv6-address | name policy-name } [ sid sid ] [ preference
preference ] [ tag tag-value ] [ description text ]
By default, no IPv6 static route is configured.

Configuring QoS policy-based traffic steering
About this task
When some public IPv6 flows are congested, you can configure traffic classification to identify the flows and redirect the traffic to SRv6 TE policies to resolve the congestion. Traffic redirection to SRv6
TE policies is based on endpoint and color. If traffic cannot match the redirect rule or the redirect
SRv6 TE policy fails, the traffic cannot be forwarded through an SRv6 TE policy but through normal
IPv6 forwarding.
