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
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.
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.
