Equal Cost Path Splitting

You can configure the maximal number of equal-cost paths that will be used when there is more than one equal-cost path to a destination. You can specify a value for the maximal number of equal-cost paths that will be used when there is more than one equal-cost path to a destination. Only OSPF routes and Static routes are able to use more than one "next hop"

• Range: 1 to 8
• Default: 8

The "next hop" algorithm that is used for forwarding when there is more than one "next hop" to a destination is Source/destination hash: A hash function is performed on the source and destination IP address of each packet that is forwarded to a multipath destination. This result is used to determine which next hop to use.

Configuring Equal Cost Path Splitting - Gaia Portal

1. In the Gaia Portal, go to the Advanced Routing > Routing Options.
2. In the Equal Cost Multipath section, in the Maximum Paths field, enter the desired number between 1 and 8.
3. Click Apply at the top of the page.

Configuring Equal Cost Path Splitting - Gaia Clish (max-path-splits)

1. Run: set max-path-splits <1-8>

   For example: set max-path-splits 2

2. Run: save config

Kernel Options - Kernel Routes

Route Injection Mechanism (RIM) enables a Security Gateway to use dynamic routing protocols to propagate the encryption domain of a VPN peer Security Gateway to the internal network and then initiate back connections. When a VPN tunnel is created, RIM updates the local routing table of the Security Gateway to include the encryption domain of the VPN peer.

In Gaia, the Route Injection Mechanism adds routes directly to the kernel. For the routes to remain in the Kernel, you must configure this option.

For more about configuring RIM, see the R80.10 Site to Site VPN Administration Guide.

Configuring Kernel Routes - Gaia Portal

1. In the Gaia Portal, go to the Advanced Routing > Routing Options.
2. In the Kernel Options area, select the Kernel Routes option.
3. Click Apply at the top of the page.
