For resilience, it is possible to connect to two CBs within one virtual switch using MLAG technology. The design of such a virtual switch resembles a classic chassis switch or a stack of switches. While the logic of the Control Plane is more or less consistent with this, the functioning of the Data Plane differs significantly. The purpose of 802.1br is to connect a remote port to a local Media Access Control (MAC) service while isolating the traffic from remote ports.<\/p>\n<h4><b>Controlling Bridge<\/b><\/h4>\n<p><\/p>\n<ul>\n<li> A single point of control<\/li>\n<li> All configuration occurs locally on the CB<\/li>\n<li> VPEX support must be activated; a reboot is required to change the operating mode<\/li>\n<li> CB is always slot No. 1<\/li>\n<li> In the current release, the CB supports simultaneous connection of up to 48 BPEs<\/li>\n<li> The CB mode is supported on certain hardware platforms (currently X670G2 and X690; other platforms will be added as they become available)<\/li>\n<li> EXOS licenses apply only to the CB<\/li>\n<li> VPEX does not require additional licenses<\/li>\n<li> Fully responsible for data-plane traffic processing and filtering<\/li>\n<li> Contains a virtual representation of each \"extended\" port<\/li>\n<\/ul>\n<p><\/p>\n<h4><b>Bridge Port Extender<\/b><\/h4>\n<p><\/p>\n<ul>\n<li> BPE devices are managed like slots in a chassis switch<\/li>\n<li> BPE slots are numbered from 100 to 162<\/li>\n<\/ul>\n<p><\/p>\n<pre><code class=\"plaintext\">Slot-1 VPEX X690-48x-2q-4c.3 # show slot\nSlots    Type                 Configured           State       Ports  Flags\n-------------------------------------------------------------------------------\nSlot-1   X690-48x-2q-4c       X690-48x-2q-4c       Operational   72   M\nSlot-100 V400-48t-10GE4       V400-48t-10GE4       Operational   52   M\nSlot-101 V400-48t-10GE4       V400-48t-10GE4       Operational   52   M\nSlot-102 V400-48t-10GE4       V400-48t-10GE4       Operational   52   M\nSlot-103 V400-48t-10GE4       V400-48t-10GE4       Operational   52   M\n<\/code><\/pre>\n<p><\/p>\n<ul>\n<li> There is no need for console or Out-of-Band IP connection to the BPE<\/li>\n<li> All configuration, monitoring, troubleshooting, and diagnostics are carried out through the CB interface<\/li>\n<\/ul>\n<p><\/p>\n<pre><code class=\"plaintext\">Slot-1 VPEX X670G2-48x-4q.8 # config vlan v100 add port 100:1,100:3\n*Slot-1 VPEX X670G2-48x-4q.9 # show port 100:1-3 statistics no-refresh\nPort   Link      Tx Pkt     Tx Byte     Rx Pkt     Rx Byte  Rx Pkt   Tx Pkt\n       State      Count       Count      Count       Count   Mcast    Mcast\n====== ===== ========== =========== ========== =========== ======= ========\n100:1  A     2126523437 &gt;9999999999          0           0       0    14383\n100:2  R              0           0          0           0       0        0\n100:3  A          21824     4759804 2126738453 &gt;9999999999       0    14383\n====== ===== ========== =========== ========== =========== ======= ========\n<\/code><\/pre>\n<p><\/p>\n<ul>\n<li> BPE do not perform local switching.

It includes port expanders for 24\/48 10\/100\/1000 Base-T ports with or without PoE support. In the 24-port models, there are two 10G ports, and in the 48-port models, there are four 10G ports.<\/p>\n<p><img decoding=\"async\" alt=\"&quot;Extreme Extended Edge,&quot; or switching based on the IEEE 802.1BR standard\" src=\"\/wp-content\/uploads\/2020\/04\/9575a2617f71bd74de9cc71a538d8a65.png\" style=\"display:block;margin: 0 auto;\" \/><\/p>\n<h4><b>Operation Features<\/b><\/h4>\n<p>\nTopologies with one or two CBs and up to four cascaded VRE in a chain are supported.

If the only CB is rebooted, the BPE will administratively disable its 'extended' ports. <br \/>\nFor ease of configuring a topology with 2 CBs, the ability to configure MLAG ports of both peers from any of the CBs has been added. This mode is called 'mlag orchestration', during which the peers synchronize part of the config relating to MLAG port settings. The configuration resembles that of user 'virtual-router'.<\/p>\n<pre><code class=\"plaintext\">Slot-1 VPEX X670G2-48x-4q.11 # start orchestration mlag \"bottom\"\n(orchestration bottom) Slot-1 VPEX X670G2-48x-4q.12 # exit\nSlot-1 VPEX X670G2-48x-4q.13 #\n<\/code><\/pre>\n<p>\nThe functionality of the 'Controlling Bridge' is available after installing a free module for EXOS that has the .xmod extension. This same module contains update images for the BPE. When the SV and BPE detect each other, CB checks the firmware version installed on the BPE and automatically updates it if necessary.<\/p>\n<p>The above-mentioned features allow for a straightforward and quick replacement of the BPE slot when needed. Since BPE slots do not store the configuration and are not tied to the system, immediately after replacing the device and powering it on, the BPE will be detected by the SV and the existing configuration will be applied. Additionally, if necessary, the firmware will be updated.<\/p>\n<p>This solution is well-suited for networks with a predominant North\/South traffic direction, such as campus networks, enterprise networks in logistics, education, business centers, and others. To reiterate, the advantages of networks built on the 'Extreme Extended Edge' solution will include:<\/p>\n<ul>\n<li> Reduction of levels in traditional network architecture from a configuration and management perspective<\/li>\n<li> Simplicity of scaling and deployment<\/li>\n<li> No need for dedicated console or out-of-band Mgmt connections to the BPE slots <\/li>\n<li> Reduction in licensing (if necessary, applicable only to SV)<\/li>\n<li> A single point for configuration, monitoring, and troubleshooting<\/li>\n<li> Displayed in NMS as a single switch<\/li>\n<li> No need for additional training and staff expansion<\/li>\n<\/ul>\n<p>Source: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/habr.com\/ru\/company\/extremenetworks\/blog\/420369\/\">habr.com<\/a>
