Abstract
Embodiments of the present disclosure provide a method and a device for storing and sending a MAC address entry, and a system. The method includes: sending, by a PE, a first packet to an RR, so that the RR determines a MAC address entry required by the PE according to the first packet, where the RR pre-stores a MAC address table, and the MAC address table includes the required MAC address entry; and receiving, by the PE, a packet which includes the required MAC address entry and is sent by the RR, and storing the required MAC address entry.
Claims21
A method, comprising:
- sending, by a provider network edge (PE), a first border gateway protocol outbound route filter (BGP ORF) packet to a route reflector (RR), wherein the first BGP ORF packet comprises a first media access control (MAC) outbound route filter (ORF) and a first route target (RT) ORF, the first MAC ORF comprises a first MAC address of a data packet, and the first RT ORF comprises a first RT corresponding to a first Ethernet virtual private network (EVPN) to which the data packet belongs;
- receiving, by the PE from the RR, a first packet comprising a MAC address entry, wherein the MAC address entry indicates routing information corresponding to the first MAC address;
- and
- storing the MAC address entry.

A method, comprising:
- receiving, by a route reflector (RR), a first border gateway protocol outbound route filter (BGP ORF) packet sent by a provider network edge (PE), wherein the first BGP ORF packet comprises a first media access control (MAC) outbound route filter (ORF) and a first route target (RT) ORF, the first MAC ORF comprises a first MAC address, the first RT ORF comprises a first RT, the first MAC address is comprised in a data packet received by the PE, and the first RT corresponds to a first Ethernet virtual private network (EVPN) to which the data packet belongs;
- determining, by the RR, the first EVPN corresponding to the first RT;
- determining, by the RR, a MAC address entry, where the MAC address entry corresponds to the first EVPN and the MAC address entry indicates routing information corresponding to the first MAC address, wherein a MAC address table comprising the MAC address entry is stored in the RR;
- and
- sending, by the RR, the MAC address entry to the PE.
2 more elements
A device, comprising:
- a processor;
- and
- a non-transitory computer-readable storage medium storing a program to be executed by the processor to cause the device to:
- send a first border gateway protocol outbound route filter (BGP ORF) packet to a route reflector (RR) to require a media access control (MAC) address entry, wherein the first BGP ORF packet comprises a first MAC outbound route filter (ORF) and a first route target (RT) ORF, the first MAC ORF comprises a first MAC address of a data packet, and the first RT ORF comprises a first RT corresponding to a first Ethernet virtual private network (EVPN) to which the data packet belongs;
- and
- receive a packet which comprises the MAC address entry and is sent by the RR, wherein the MAC address entry indicates routing information corresponding to the first MAC address;
- and
- wherein the device is configured to store the MAC address entry.

A device, comprising:
- a processor;
- and
- a non-transitory computer-readable storage medium storing a program to be executed by the processor to cause the device to:
- receive a first border gateway protocol outbound route filter (BGP ORF) packet sent by a provider network edge (PE), wherein the first BGP ORF packet comprises a first media access control (MAC) outbound route filter (ORF) and a first route target (RT) ORF, the first MAC ORF comprises a first MAC address, the first RT ORF comprises a first RT, the first MAC address is comprised in a data packet received by the PE, and the first RT corresponds to a first Ethernet virtual private network (EVPN) to which the data packet belongs;
- determine the first EVPN according to the first RT, and determine a MAC address entry which corresponds to the first EVPN and the MAC address entry indicates routing information corresponding to the first MAC address, wherein the device is configured to store a MAC address table comprising the MAC address entry;
- and
- send the MAC address entry to the PE;
- and
- wherein the device is further configured to configured to store the MAC address table.
