Configuring Ecmp Static Routes - Lenovo RackSwitch G8264 Application Manual

Configuring ECMP Static Routes

1. Add a static route (IP address, subnet mask, gateway, and interface number).
2. Add another static route with the same IP address and mask, but a different
gateway address.
3. Select an ECMP hashing method (optional).

To configure ECMP static routes, add the same route multiple times, each with the
same destination IP address, but with a different gateway IP address. These routes
become ECMP routes.
RS G8264(config)# ip route 10.10.1.1 255.255.255.255 100.10.1.1 1
RS G8264(config)# ip route 10.10.1.1 255.255.255.255 200.20.2.2 1
RS G8264(config)# ip route ecmphash [sip|dipsip]
You may add up to 32 gateways for each static route.
Use the following commands to check the status of ECMP static routes:
RS G8264(config)# show ip route static
Current static routes:
