Abstract
Embodiments of this application disclose a routing management method, used to advertise an address segment routing policy. The method in the embodiments of this application includes: A control plane function assigns an internet protocol IP address to user equipment. The control plane function determines an IP address segment, where the IP address belongs to the IP address segment. The control plane function sends information used to identify the IP address segment to a user plane function, where the IP address segment is used to advertise a routing policy.
Claims11
A routing management method comprising:
- assigning, by a control plane function, an internet protocol (IP) address to user equipment;
- determining, by the control plane function, an IP address segment, wherein the IP address belongs to the IP address segment;
- and
- sending, by the control plane function, information used to identify the IP address segment to a user plane function, wherein the IP address segment is used to advertise a routing policy wherein:
- the information used to identity the IP address segment comprises the IP address and an IP address mask;
- and the sending, by the control plane function, of the information used to identify the IP address segment to the user plane function comprises:
- sending, by the control plane function, of the IP address and the IP address mask to the user plane function;
- and
- the sending, by the control plane function, of the IP address and the IP address mask to the user plane function comprises:
- sending, by the control plane function, a session establishment request message to the user plane function, wherein the session establishment request message comprises an IP address attribute-value pair and an IP address mask attribute-value pair, the IP address attribute-value pair carries the IP address, and the IP address mask attribute-value pair carries the IP address mask.
