Summary
The Routes page displays the router's ARP table and active IPv4 and IPv6 routes. This chapter is an overview of the Routes page of RUTX11 routers.
General Routes
ARP
The Address Resolution Protocol (ARP) is a communication protocol used for mapping an Internet Protocol address (IP address) to a physical machine's link layer address (MAC address) belonging to the local network.
The ARP section displays the router's ARP cache (also known as ARP table) data. The ARP cache contains information on each known MAC address and its corresponding IP address. When the router receives a packet destined for a local host, the ARP program attempts to find a physical host or MAC address in the ARP cache that matches the IP address. If the ARP cache doesn't contain the needed IP address, ARP broadcasts a request packet to all LAN machines in order to find the device with the IP address in question.
The figure below is an example of the ARP cache section:
| Field name | Value | Description |
|---|---|---|
| IP address | ip; Default: none | IP address of a local host. |
| MAC address | mac; Default: none | MAC address of a local host. |
| Interface | string; Default: none | Interface through which the router is associated with the host. |
You can also view the ARP cache via shell using the arp or ip neigh commands, depending on which output your prefer:
root@Teltonika-RUTX11:~#

192.168.1.151 0x1 0x2 18:d6:c7:00:00:00 * br-lan
root@Teltonika-RUTX11:~#
ip neigh
192.168.1.151 dev br-lan lladdr 18:d6:c7:00:00:00 REACHABLE
IPv4 Routes
The IPv4 Routes section displays the router's routing table. A routing table contains a list of routes to network destinations associated with and known by the router.
The figure below is an example of the Active IP routes section:
| Field name | Value | Description |
|---|---|---|
| Network | string; Default: none | Associated network interface name. |
| Target | ip | ip/netmask; Default: none | Destination network address. |
| IPv4 gateway | ip; Default: none | Indicates the IP address of the gateway through which the target network can be reached. |
| Metric | integer [0..4,294,967,295]; Default: none | Metrics help the router choose the best route among multiple feasible routes to a destination. The route will go in the direction of the gateway with the lowest metric value. |
| Table | string | integer; Default: none | Name or number of the associated routing table. |
You can also view the routing table via shell using the route or ip route commands, depending on which output your prefer:
root@Teltonika-RUTX11:~#

IPv6 routes
The IPv6 Routes section displays the router's IPv6 routing table.
The figure below is an example of the IPv6 routes section:
| Field name | Value | Description |
|---|---|---|
| Network | string; Default: none | Associated network interface name. |
| Target | ip6 | ip6/netmask; Default: none | Destination network address. |
| IPv6-Gateway | ip6 | ip6/netmask; Default: none | Source of the network address. |
| Metric | integer [0..4,294,967,295]; Default: none | Metrics help the router choose the best route among multiple feasible routes to a destination. The route will go in the direction of the gateway with the lowest metric value. |
| Table | string | integer; Default: none | Name or number of the associated routing table. |
You can also view the routing table via shell using the route -A inet6 or ip -6 route show commands, depending on which output your prefer:
root@Teltonika-RUTX11:~#
ip -6 route
fdb2:7fc0:b88f::/64 dev br-lan proto static metric 1024
ff00::/8 dev eth1 proto kernel metric 256
ff00::/8 dev br-lan proto kernel metric 256
ff00::/8 dev ath1 proto kernel metric 256
IPv6 Neighbours
The IPv6 Neighbours section displays IPv6 associated neighbours.
The figure below is an example of the Active IPv6 Neighbours section:
| Field name | Value | Description |
|---|---|---|
| IPv6 Address | ip6; Default: none | IPv6 address of the associated neighbour. |
| MAC Address | ip6; Default: none | MAC address of the associated neighbour. |
| Interface | string; Default: none | Name of the associated network interface. |
Dynamic routes
The Dynamic routes page contains multiple sections, each of which displays the routing data of a Dynamic Routing protocol supported by the device. Data is only displayed once a protocol is configured and enabled. Else, each section is empty.
