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.
If you’re having trouble finding this page or some of the parameters described here on your device’s WebUI, you should turn on “Advanced WebUI” mode. You can do that by clicking the “Basic” button under “Mode”, which is located at the top-right corner of the WebUI.
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:
You can also view the ARP cache via shell using the arp or ip neigh commands, depending on which output your prefer:
IP address HW type Flags HW address Mask Device
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
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:
You can also view the routing table via shell using the route or ip route commands, depending on which output your prefer:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
default 192.168.2.1 0.0.0.0 UG 0 0 0 eth1
192.168.1.0 * 255.255.255.0 U 0 0 0 br-lan
root@Teltonika-RUTX11:~# ip route
default via 192.168.2.1 dev eth1
192.168.1.0/24 dev br-lan proto kernel scope link src 192.168.1.1
The Active IPv6 Routes section displays the router’s IPv6 routing table.
The figure below is an example of the Active IPv6 routes section:
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
The IPv6 Neighbours section displays IPv6 associated neighbours.
The figure below is an example of the Active IPv6 Neighbours section:
