    摘要： According to an example, to forward a packet, an access layer device searches a Layer 2 forwarding table according to a source Media Access Control (MAC) address of the packet, and replaces the source MAC address with a mapped virtual MAC address in a matching Layer 2 forwarding entry. The Layer 2 forwarding table is searched according to a destination MAC address of the Ethernet packet. In response to determining that a Layer 2 forwarding entry matching the destination MAC address of the Ethernet packet does not include a MAC address mapped to the destination MAC address, Very Large Layer 2 (VLL2) network protocol encapsulation is performed on the Ethernet packet of which the source MAC address is replaced according to an egress port in the Layer 2 forwarding entry matching the destination MAC address; and the Ethernet packet encapsulated with a VLL2 network protocol header is sent via the egress port.

    摘要： According to an example, a relay device receives a DHCP request packet sent from a DHCP client, in which the DHCP request packet includes a user information sub-option including a node identifier of the DHCP client. The relay device adds a node identifier of the relay device and path information of receiving the DHCP request packet by the relay device to a relay agent information sub-option in the DHCP request packet, and forwards the DHCP request packet to a DHCP server, so that the DHCP server determines network topology according to the user information sub-option and the relay agent information sub-option.

    摘要： After a RB in a TRILL network starts or establishes neighbor relationships with other RBs, the RB sends a nickname conflict detection packet. After receiving the packet, a DRB replies with a response packet carrying nickname information corresponding to all LSPs in the LSDB to the RB. The RB receives the response packet sent from the DRB, checks whether a nickname has a conflict with nicknames of other RBs and regenerates a nickname that is not conflict with the nicknames of other RBs.
