Equal Cost Assorted Path (ECMP) Forwarding
For amount balancing, the Security Appliance offers the ECMP that supports up to three equal-cost routes to the
same destination per interface. Based on an algorithm that hashes the antecedent and destination IP addresses, the
Security Appliance amount balances the cartage amid the authentic gateways. Note that this does not guarantee
diverting cartage appropriately amid the gateways.
Example 6-6 shows three equal-cost changeless routes for destination arrangement 10.1.1.0/24, forwarding cartage to
three altered gateways on the alfresco interface.
Example 6-6. Configuring ECMP (Equal Cost Assorted Path) Changeless Routes
hostname(config)# avenue alfresco 10.1.1.0 255.255.255.0 209.165.201.1
hostname(config)# avenue alfresco 10.1.1.0 255.255.255.0 209.165.201.2
hostname(config)# avenue alfresco 10.1.1.0 255.255.255.0 209.165.201.3
Similarly, up to three equal-cost absence routes can be authentic per device. Example 6-7 shows three equal-cost
default routes, forwarding cartage to three altered gateways on the alfresco interface.
Example 6-7. Configuring ECMP (Equal Cost Assorted Path) Absence Routes
hostname(config)# avenue alfresco 0.0.0.0 0.0.0.0 209.165.201.1
hostname(config)# avenue alfresco 0.0.0.0 0.0.0.0 209.165.201.2
hostname(config)# avenue alfresco 0.0.0.0 0.0.0.0 209.165.201.3
Note
ECMP is not accurate beyond assorted interfaces.
