Advanced Routing

Routing is the process of forwarding packets from one network to the destination address in another network. Router, a packet forwarding device between two networks, is designed to transmit packets based on the various routes stored in routing tables. Each route is known as a routing entry.

Hillstone devices are designed with Layer 3 routing. This function allows you to configure routing options and forward various packets via VRouter. System implements with a default VRouter trust-vr, and also supports multiple VRouters (multi-VR).

Hillstone devices support destination routing, ISP routing, Source-Based Routing (SBR), Source-Interface-Based Routing (SIBR), Destination-Interface-Based Routing (DIBR), Policy-Based Routing (PBR), dynamic routing (including RIP, OSPF and BGP) and Equal Cost MultiPath Routing (ECMP).

  • Destination Routing: A manually-configured route which determines the next routing hop according to the destination IP address.

  • DIBR: A manually-configured route which determines the next routing hop according to the destination IP address and ingress interface.
  • SBR: Source IP based route which selects routers and forwards data according to the source IP address.

  • SIBR: Source IP and ingress interface based route.

  • ISP Profile: Add a subnet to an ISP.

  • ISP Routing: A kind of route which determines the next hop based on different ISPs.
  • PBR: A route which forwards data based on the source IP, destination IP address and service type.

  • Dynamic Routing: Selects routers and forwards data according to the dynamic routing table generated by dynamic routing protocols (RIP, OSPF or BGP).

  • ECMP: Load balancing traffic destined to the same IP address or segment in multiple routes with equal management distance.

When forwarding the inbound packets, the device will select a route in the following sequence: PBR > SIBR > SBR > DIBR > Destination routing/ISP routing/Proximity routing/Dynamic routing.

Routing supports IPv4 and IPv6 address. If IPv6 is enabled, you can configure IPv6 address entry for the routing rule.
