A MikroTik system administrator implemented OSPF Routing protocol in the network.
But realized that he has a static route on the routers. What can be done to make the static
route work as a failover whenever the dynamic routing protocol fails.
A MikroTik system administrator implemented OSPF Routing protocol in the network. But realized that he has a static route on the routers. What can be done to make the static route work as a failover whenever the dynamic routing protocol fails.
- Delete all static routes because there is no way for it to work with OSPF
- He should use "netwatch" to trigger static routes whenever OSPF fails
- He should manually disable the static routes and enable them whenever OSPF fails
- He should increase the administrative distance of the static route (correct)
/ip route configuration on router,
/ip route add gateway=192.168.0.1
/ip route add dst-address=192.168.1.0/24 gateway=192.168.0.2
/ip route add dst-address=192.168.2.0/24 gateway=192.168.0.3
/ip route add dst-address=192.168.3.0/26 gateway=192.168.0.4
Router needs to send packets to 192.168.3.240. Which gateway will be used?

- 192.168.0.1 (correct)
RouterOS device has acquired an IP address from an ISP using DHCP client. The same
router is used for assigning IP addresses to local users using DHCP server, masquerade rule is
configured properly. Packets that are coming from the ISP have TTL=1. Select correct
statement:

- Router does not have access to the Internet, but clients have

You have a router with the following IP addresses:
ether1: 10.40.1.1/24
ether2: 10.250.1.1/30
ether3: 10.251.1.1/30
wlan1: 10.50.1.1/30
wlan2: 10.50.2.1/30
You have a customer directly connected to ether2, and another customer directly connected to
ether3. Your wireless radios are used for wireless connectivity to two different towers, and
ether1 goes to another wireless access point for other subscribers. You need all of the subnets
distributed across your OSPF Network
You need to configure OSPF to talk on this router, what would be the best configuration.

Consider two geographically separate sites. At each site, there is a RouterOS device.
Ether1 is connected to the LAN and Ether2 is connected to the Internet.
An EoIP tunnel is created between the two routers. And on both routers a Bridge interface
with the EoIP tunnel and Ether1 as ports.
10 users are connected at site A and 30 users at site B. All users are configured to use a
DHCP server to obtain IP address configuration.
What is the minimum number of DHCP servers needed, (select correct configuration):

When adding a static route, you must always ensure that you add both the gateway and the
interface.

Consider the following diagram. We want to communicate from a device on LAN1 to a
device on LAN2. Assuming that all necessary configurations are already included on R2,
which of the following configurations in R1 would enable this communication?
