RUTX11 Routes

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.

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.

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:

Networking rutx manual routes arp v2.png
Field NameValueDescription
IP addressip; Default: noneIP address of a local host.
MAC addressmac; Default: noneMAC address of a local host.
Interfacestring; Default: noneInterface 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:~# arp
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

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:

Networking rutx09 rutx11 manual routes ipv4 routes v2.png
Field NameValueDescription
Networkstring; Default: noneAssociated network interface name.
Targetip | ip/netmask; Default: noneDestination network address.
IPv4 gatewayip; Default: noneIndicates the IP address of the gateway through which the target network can be reached.
Metricinteger [0..4,294,967,295]; Default: noneMetrics 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.
Tablestring | integer; Default: noneName 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:~# route
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

Active IPv6 routes #

The Active IPv6 Routes section displays the router’s IPv6 routing table.

The figure below is an example of the Active IPv6 routes section:

Networking rutx09 rutx11 manual routes active ipv6 routes v2.png
Field NameValueDescription
Networkstring; Default: noneAssociated network interface name.
Targetip6 | ip6/netmask; Default: noneDestination network address.
Sourceip6 | ip6/netmask; Default: noneSource of the network address.
Metricinteger [0..4,294,967,295]; Default: noneMetrics 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.
Tablestring | integer; Default: noneName 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:

Networking rutx manual routes ipv6 neighbours v1.png
Field NameValueDescription
IPv6 Addressip6; Default: noneIPv6 address of the associated neighbour.
MAC Addressip6; Default: noneMAC address of the associated neighbour.
Interfacestring; Default: noneName of the associated network interface.
