How does multi chassis LAG work?

Multichassis link aggregation groups (MC-LAGs) enable a client device to form a logical LAG interface between two MC-LAG peers. An MC-LAG provides redundancy and load balancing between the two MC-LAG peers, multihoming support, and a loop-free Layer 2 network without running STP.

What is multi chassis?

A multi-chassis link aggregation group (MLAG or MC-LAG) is a type of link aggregation group (LAG) with constituent ports that terminate on separate chassis, primarily for the purpose of providing redundancy in the event one of the chassis fails.

How do I set up MC-LAG?

The following is an example CLI configurations for a MCLAG:

  1. Create a LAG by configuring the ports for each FortiSwitch unit: config switch trunk. edit “MCLAG-ICL-trunk”
  2. Set up the MCLAG: config switch trunk. edit “first-mclag”
  3. If you do not want the MCLAG to use the STP: config switch global. set mclag-stp-aware disabled.

What is the difference between lag and MLAG?

MLAG is the ability of switches to appear as a single switch at layer 2, so that bundles of links in the form of LAGs can be diversely connected to each switch and appear as one. LAGs are typically created North & South i.e. between host and switch, whereas MLAG is created and expanded in an East & West direction.

What is the difference between MLAG and vPC?

MLAG is a public protocol that is supported by almost every vendor using their own custom rolled implementation, while vPC is a Cisco Nexus specific protocol, not all the vendors have this technology.

What is Virtual Router in Juniper?

Understanding Virtual Routing Instances on EX Series Switches. Virtual routing instances allow administrators to divide a Juniper Networks EX Series Ethernet Switch into multiple independent virtual routers, each with its own routing table.

Which two combinations are supported when configuring a virtual chassis fabric?

Supported VCF Configurations The following VCF configurations are supported based on either QFX5110 or QFX5100 switches as the spine members, as indicated: A non-mixed QFX5100 VCF has QFX5100 switches as spine members, and supports only QFX5100 switches as leaf members.

What is multi chassis EtherChannel?

“Multichassis EtherChannel (MEC) is a Layer 2 multipathing technology. This form of EtherChannel allows a connected node to terminate the EtherChannel across the two physical Cisco Catalyst 6500 Series Switches that make up the VSS leading to creating simplified loop-free Layer 2 topology.

What is aggregation in networking?

In computer networking, link aggregation is the combining (aggregating) of multiple network connections in parallel by any of several methods, in order to increase throughput beyond what a single connection could sustain, to provide redundancy in case one of the links should fail, or both.

Is MLAG the same as vPC?

Is MLAG proprietary?

No proprietary protocol used to connect an MLAG pair to servers or other switches. Interconnect to other switches or servers can use static LAG or IEEE 802.3ad LACP. Up to 16 1GbE or 100GbE ports can be aggregated together and spread across the two switches.
