Configure import and export lists under /ip route vrf, import-route-targets and export-route-targets. Route installation in VRF tables is controlled by BGP extended communities attribute. Usually there will be one-to-one correspondence between route distinguishers and VRFs, but that's not a mandatory requirement. First configure the route distinguisher for a VRF. You can use multi-protocol BGP with VPNv4 address family to distribute routes from VRF route tables - not only to other routers, but also to different routing tables in the router itself. Note: When a DHCP-Relay server is attached to an interface in a vrf, the communications from that DHCP-Relay to the remote DHCP-Server will not be routed via the vrf! (You can still override this behavior with custom route lookup rules, as they have precedence.) For VRFs: if lookup is done, and no route is found in VRF route table, the lookup fails with "network unreachable" error. For policy routing: after route lookup has been done in policy-route table, and no route was found, route lookup proceeds to the main route table. Read-only route attribute gateway-table displays information about which table is used for a particular route (default is main). Routes in VRF tables resolve next-hops in their own route table by default, while policy routes always use the main route table.The main differences between VRF tables and simple policy routing are: The existing policy routing support in MT RouterOS is not changed but on the other hand, it is not possible to have policy routing within a VRF. There is exactly one policy route table for each active VRF. Technically VRFs are based on policy routing. Connected routes from interfaces belonging to a VRF will be installed in the right routing table automatically. You can now add routes to that VRF - simply specify routing-mark attribute. To create a VRF, configure it under /ip route vrf. VRFs solve the problem of overlapping IP prefixes, and provide the required privacy (via separated routing for different VPNs). Unlike BGP VPLS, which is OSI Layer 2 technology, BGP VRF VPNs work in Layer 3 and as such exchange IP prefixes between routers. RouterOS 3.x allows to create multiple Virtual Routing and Forwarding instances on a single router. 2.3 Variation: replace the Cisco with another MT.2.2 A more complicated setup (changes only).I would like to be able to paste these lists into a simple executable windows program and have it output in ascii text form a script ready to paste into the CLI interface of the mikrotik router. There several hundred in total I would like to be able to enter from 1 set of data at least 100 sets at one time. I would have a list of customer numbers, customer IP address and new static public IP to-addresses=Īdd action=netmap chain=dstnat comment="CustomerNumber" dst-address= The 'srcnat and 'dstnat' scripts for each customer should be together, not all srcnat then all dstnats for example.Įxample of output required for each set of customer dataĪdd action=netmap chain=srcnat comment="CustomerNumber" src-address= txt file ready to be copied & pasted it into the router command line interface. I need a script generator to write two Mikrotik NAT rules in the following format for each set of customer data, and save the output as a.
