A random MAC address will be generated in this case. ipv6 address add address=2003::1/64 advertise=no interface=lobridgeĪlternative solution is to use a fake EoIP tunnel interface instead of bridge. interface bridge add name=lobridge auto-mac=no admin-mac=01:00:00:00:01:00
Since IPv6 link-local address is needed for IPv6 to function properly on an interface, this means that by default the empty bridge interface cannot be used as IPv6 loopback interface.Īdd an empty bridge, and specify bridge MAC address manually: MT RouterOS does not generate IPv6 link-local addresses on interfaces with zero MAC address (because of high address collision probability). Please let me know if the above answer is correct or not. Some engineers used the loopback for managing routers and reserve a network segment for the loopbacks. All traffic sent to it loops back and just targets services on. Use an address that is not used elsewhere on your network. ip address add address=10.0.0.1/24 interface=lobridgeĮmpty bridge interface has zero MAC byte default. The loopback networking interface is a virtual network device implemented entirely in software. In MT RouterOS the recommended way to add a loopback interface for IPv4 is to create a new empty bridge interface: Such addresses are useful, for example, as source addresses for TCP connections between two routers that have more that one physical interfaces between them. It can be used to hold addresses that belong to the "router itself" and not to any particular outgoing interface.
In some cases it is necessary to have a kind of loopback interface.
