User Manual UMN:CLI V5812G 8 System Main Functions Virtual Local Area Network (VLAN) The first step in setting up your bridging network is to define VLAN on your switch. VLAN is a bridged network that is logically segmented by customer or function. Each VLAN contains a group of ports called VLAN members.
Page 210: Port-Based Vlan
UMN:CLI User Manual V5812G 8.1.1 Port-based VLAN The simplest implicit mapping rule is known as port-based VLAN. A frame is assigned to a VLAN based solely on the switch port on which the frame arrives. In the example depicted in Fig.

Command Mode Description Creates new VLAN by assigning VLAN ID: vlan create VLANS Bridge VLANS: VLAN ID (1-4094, multiple entries possible) The variable VLANS is a particular set of bridged interfaces. Frames are bridged only among interfaces in the same VLAN.
Page 212: Protocol-Based Vlan
8.1.3 MAC-based VLAN The V5812G can assign a frame to a VLAN based on the source MAC address in the received frames. Using this, all frames emitted by a given end station will be assigned to the same VLAN, regardless of the port on which the frame arrives. This is useful for mobility application.
Page 213: Subnet-Based Vlan
V5812G 8.1.4 Subnet-based VLAN An IP address contains two parts: a subnet identifier and a station identifier. The V5812G performs two operations to create IP subnet-based VLANs. • Parse the protocol type to determine if the frame encapsulates an IP datagram.
Page 214: Vlan Description
UMN:CLI User Manual V5812G There are two methods for identifying the VLAN membership of a given frame: • Parse the frame and apply the membership rules (implicit tagging). • Provide an explicit VLAN identifier within the frame itself. VLAN Tag A VLAN tag is a predefined field in a frame that carries the VLAN identifier for that frame.

Page 374: Pim-Sm
UMN:CLI User Manual V5812G 9.3.3 PIM-SM Rendezvous Point Tree (RPT) PIM-SM mainly uses a shared tree to deliver multicast traffic, called the RP tree (RPT). As its name implies, it relies on a core router called the Rendezvous Point (RP) that receives all multicast traffic from the sources and forwards that traffic to the receivers.
Page 375: Fig. 9.7 Shortest Path Tree
User Manual UMN:CLI V5812G To establish the SPT to the multicast source, the DR sends the join message with (S, G) state toward that source. When the SPT between the receiver and source is established, and multicast traffic is sent via that distribution tree, the DR sends the prune message with (*, G) state toward the RP to prune the existing shared tree to receive the traffic.
Page 376: Rendezvous Point
Static RP To elect the RP among candidate RPs in the shared tree, the V5812G supports the BSR mechanism (see Section 9.3.3.2) and static RP, and also supports the simultaneous use of those.
Page 377 User Manual UMN:CLI V5812G Interface for Candidate RP To elect the RP, each candidate RP sends its information to the BSR. This advertisement contains the IP address and priority of the candidate RP and the multicast groups that it can service. The BSR then periodically distributes the bootstrap message that includes a set of the information received from each candidate RP (RP-set) to all the routers in the PIM-SM domain.

After the registration, the DR periodically sends the PIM null-register message that does not contain the encapsulated multicast traffic to the RP, and the RP returns the register-stop message.
Page 381: Spt Switchover
User Manual UMN:CLI V5812G Source Address of Register Message You can specify the source IP address of PIM register messages sent by the DR. This address is used to send corresponding PIM register-stop messages in response. By default, the source address of register messages is the IP address of the interface toward the RP.

User Manual UMN:CLI V5812G 10 IP Routing Protocol 10.1 Border Gateway Protocol (BGP) The Border Gateway Protocol (BGP) is an exterior gateway protocol (EGP) that is used to exchange routing information among routers in different autonomous systems (AS). BGP routing information includes the complete route to each destination. BGP uses the routing information to maintain a database of network reachability information, which it exchanges with other BGP systems.
Page 388: Basic Configuration
The ZebOS type requires no specific configuration for sending out BGP community and extended community attributes. ZebOS type is the default for the V5812G. To select configuration type of the BGP router, use the following command.
