For example, we could refer to the network 192.168.1.0 or 172.16.0.0 as a “Network Address.” network address - a standard way to refer to an IPv4 address assigned to a network.The IPv4 network consists of three addresses: Each octet is converted to a decimal format and separated by a dot. IPv4 uses 4-byte addresses which are segmented in four 8-bit fields called octets. You can use /ip address print detail to see which interface the address belongs to. Configuring an IP address to a physical interface included in a bridge would mean actually setting it on the bridge interface itself. In the case of bridging or PPPoE connection, the physical interface may not have any address assigned, yet be perfectly usable. It is possible to add multiple IP addresses to an interface or to leave the interface without any addresses assigned to it. The network prefix and the broadcast address are calculated automatically. In most cases, it is enough to specify the address, the netmask, and the interface arguments. It's also possible to specify an IP address followed by a slash "/" and the number of bits that form the network address. The network address value is calculated by binary AND operation from a network mask and IP address values. For proper addressing the router also needs the network mask value, id est which bits of the complete IP address refer to the address of the host, and which - to the address of the network. A typical (IPv4) address consists of four octets.

Set the OSPF router-id on R2 too: /routing ospf instance On both routers, R1 and R2 add the following: /routing ospf interface add network-type=point-to-pointĪdditionally set the OSPF router-id on R1: /routing ospf instance This should improve the convergence time of OSPF.

The networking scenario is easy, it is using 2 directly connected CHR appliances, via the ether1 interface. But that is enough to configure a virtual lab with 2 or more CHR routers using a dynamic routing protocol. The free CHR router has a maximal 1Mbit/s throughput. This virtual appliance, called CHR, can be downloaded at the gn3 marketplace website or directly on the MikroTik website. MikroTik distributes a free to use appliance with its RouterOS called operating system.
