Static Route Overview

This topic provides an overview of static route table and all associated system routes.

Route table

Yeastar P-Series PBX System provides a route table that contains default system route entries and custom route entries.

Default system entries
After you configure the system network, the system automatically adds system routes to the route table for traffic management. You cannot delete the system routes.
For more information, see System route entries.
Custom route entries
If the system is in Dual network mode, you need to add a static route to override the default system routes, routing the packets from specific IP address to the specified destination. For more information, see Add a Static Route.

System route entries

System route entries are automatically added after you configure the PBX network. The following route entries are considered as system route entries:

  • A default route entry. The packets that are destined to any unknown destinations will be routed to the default gateway.
  • A route entry destined for the IP address range of LAN or WAN interface. The packets that are destined to the IP address range can be sent directly to the destination.

Example:

The following example describes the automatically added system routes.

Network settings
Both LAN interface and WAN interface are enabled, and LAN is the default interface. The detailed network information is as the followings.
LAN (Default Interface) WAN
IP address 192.168.6.124 10.10.1.18
Subnet mask 255.255.255.0 255.255.255.0
Gateway 192.168.6.1 10.10.1.1
Preferred DNS Server 192.168.1.1 10.10.1.1
System route entries
The following route entries are automatically added to the routing table of the PBX.
  • The route entry with the Destination of default is the default route entry. By default, all the packets will be routed to the gateway 192.168.6.1 through LAN interface.
  • The route entry with the Destination of 10.10.1.0/255.255.255.0 is the route entry that is automatically added for WAN interface.

    The packets for the network 10.10.1.0/255.255.255.0 don't need to be routed. The network is locally connected, so packets can be sent directly to the destination.

  • The route entry with the Destination of 192.168.6.0/255.255.255.0 is the route entry that is automatically added for LAN interface.

    The packets for the network 192.168.6.0/255.255.255.0 don't need to be routed. The network is locally connected, so packets can be sent directly to the destination.
