One. BGP ECMP is disabled.
This command triggers the BGP decision process, causing BGP to re-install the entire BGP routing table into the IP forwarding table. This activity requires a significant amount of switch processor resources, so we recommend that you enable or disable the BGP ECMP feature before enabling the BGP protocol globally on a VR. To ensure that BGP ECMP routes are programmed in the hardware, enter the enable iproute sharing command.
Note
BGP must be disabled before you can change the configuration with this command.
The following command enables BGP ECMP and sets the maximum number of paths to 4 (the maximum number of possible paths is 64):
configure bgp maximum-paths 4
This command was first available in ExtremeXOS 12.1.3.
This command is available on platforms that support the appropriate license. For complete information about software licensing, including how to obtain and upgrade your license and which licenses support the BGP feature, see the Switch Engine v33.1.1 Licensing Guide document.
