EOS 4.23.1F added basic MLAG support for 7800R3, 7500R3 and 7280R3 platforms. The MLAG features that are currently

As described in the Multi VTEP MLAG TOI, singly connected hosts can lead to suboptimal peer link utilisation. By

4.22.1F introduces support for ip address virtual for PIM and IGMP in MLAG and Vxlan. On a VLAN, the same IP address can

When MLAG peer link goes down, the secondary peer assumes the primary peer is down/dead, and takes over the primary

In an MLAG setup, periodic TCP/UDP heartbeats are sent over peer link to ensure IP connectivity between peers. Prior

The objective of Maintenance Mode on MLAG is to gracefully drain away the traffic (L2 and BGP) flowing through a switch

If an MLAG flaps on one peer, then we may have to remap the MAC addresses learned, such that the reachability is via the

As of release 4.20.5F, this feature is now available on 7160 series switches. Here is a link to earlier

On a MLAG chassis, MAC addresses learned on individual peers are synced and appropriate interfaces are mapped to

In conventional VXLAN deployments, each MLAG pair of switches are represented as a common virtual VTEP.

[L2 EVPN] and  [Multicast EVPN IRB] solutions allow for the delivery of customer BUM (Broadcast, Unknown unicast and Multicast) traffic in a L2VPN and L3VPNs respectively using multicast in the underlay network.

NAT Peer State Synchronization feature provides redundancy and resiliency for Dynamic NAT across a pair of devices in an attempt to mitigate the risk of single NAT device failure. Each switch advertises connection state updates to its peer.  State update consists of connection creation, connection state change (TCP mostly) or connection tear down

From the Precision Time Protocol (PTP) perspective, Multi Chassis Link Aggregation (MLAG) peers are two physical
