High Availability Solutions
High availability documentation covers redundancy and load-sharing designs such as bonding, VRRP, multi-chassis link aggregation, and WAN load balancing. Use this section to improve service continuity and link resilience.
Bonding
Bonding allows combining multiple ethernet interfaces into a single virtual link for higher bandwidth and failover, with MikroTik RouterOS supporting various modes including LACP and hardware offloading for specific chips.
Load Balancing

Multi-chassis Link Aggregation Group
MLAG in RouterOS enables physical redundancy by configuring LACP bonds across two devices, allowing the client to perceive a single connection while ensuring failover. It uses ICCP for peer communication, supports STP protocols, and requires careful VLAN configuration on dedicated ports. MLAG is CPU-intensive for large networks, and compatibility with L3 offloading or MVRP is limited

VRRP
This page describes the Virtual Router Redundancy Protocol (VRRP) in MikroTik RouterOS, explaining how it provides router redundancy through IPv4/IPv6 multicast communication and prioritized election among routers. It covers VRRP configuration, virtual MAC address assignment, owner/master/backup roles, and emphasizes version compatibility and warning about deprecated authentication in VRRPv
