Bonding with diffirence switch mikrotik driver#

This standard also mandates that frames will be delivered in order and connections should not see mis-ordering of packets. It includes automatic configuration of the aggregates, so minimal configuration of the switch is needed. Bonding modes 802.3adĨ02.3ad mode is an IEEE standard also called LACP (Link Aggregation Control Protocol). When unplugging one of the cables, the failure will be detected almost instantly compared to ARP link monitoring. MII monitoring is configured by setting the variables link-monitoringĮnable MII Type2 monitoring: interface bonding> set 0 bonding> set 0 link-monitoring=mii-type-2

Main disadvantage is that MII monitoring can’t tell if the link can actually pass packets or not, even if the link is detected as being up. This mode should be set only if MII type 1 is not supported. This method is less efficient but can be used on all devices. MII Type 2 – deprecated calling sequences within the kernel are used to determine if link is up.

If device driver does not support this option then link will appear as always up.

MII Type 1 – device driver determines whether link is up or down.

In RouterOS it is possible to configure MII monitoring in two ways: MII monitoring monitors only the state of the local interface. Unplug one of the cables to test if the link monitoring works correctly, you will notice some ping timeouts until arp monitoring detects link failure. Value in our example, RouterOS sets arp-interval Having additional targets increases the reliability of the ARP monitoring.Įnable ARP monitoring interface bonding> set 0 link-monitoring=arp bonding> set 0 link-monitoring=arp arp-ip-targets=172.16.0.1 If only one target is set, the target itself may go down. It is possible to specify multiple ARP targets that can be useful in High Availability setups. Meaning of each option is described later in this article.

ARP monitoring is enabled by setting three properties link-monitoring Otherwise all replies from the ARP targets will be received on the same link which could cause other links to fail. If balance-rr and balance-xor modes are set, then the switch should be configured to evenly distribute packets across all links. This also gives assurance that traffic is actually flowing over the links. ARP MonitoringĪRP monitoring sends ARP queries and uses the response as an indication that the link is operational. It is not possible to use both methods at the same time due to restrictions in the bonding driver. Bonding in RouterOS currently supports two schemes for monitoring a link state of slave devices: MII and ARP monitoring. In the above example, if one of the bonded links were to fail, the bonding driver will still continue to send packets over the failed link which will lead to network degradation. It is critical that one of the available link monitoring options is enabled. Note: bonding interface needs a couple of seconds to get connectivity with its peer.

Add bonding interface on interface bonding> add slaves=ether1,ether2Īnd on Router2: interface bonding> add slaves=ether1,ether2Īdd addresses to bonding interfaces: ip address> add address=172.16.0.1/24 address> add address=172.16.0.2/24 interface=bonding1.

Make sure that you do not have IP addresses on interfaces which will be enslaved for bonding interface!.

To make this possible, follow these steps: Let us assume that we have 2 NICs in each router (Router1 and Router2) and want to get maximum data rate between 2 routers. Bonding is a technology that allows aggregation of multiple ethernet-like interfaces into a single virtual link, thus getting higher data rates and providing failover.
