Use Case: ECMP with BGP routing

To configure ECMP with BGP routing protocol, perform the following steps:

1. Log on to the cluster IP address.

2. Enable BGP routing protocol.

   > enable ns feature bgp
   

3. Add VLAN and bind the required interfaces.

   > add vlan 985
   > bind vlan 985 -ifnum 0/0/1 1/0/1
   

4. Add the spotted IP address and bind them to the VLAN.

   > add ns ip 10.100.26.14 255.255.255.0 -ownerNode 1 -dynamicRouting ENABLED
   > add ns ip 10.100.26.15 255.255.255.0 -ownerNode 2 -dynamicRouting ENABLED
   > bind vlan 985 -ipAddress 10.100.26.10 255.255.255.0
   

5. Configure BGP routing protocol on ZebOS using vtysh shell.

   > vtysh conf t router bgp 65535 neighbor 10.100.26.1 remote-as  65535
   

6. Configure BGP on the external switch. The following sample configurations are provided for the Cisco® Nexus 7000 C7010 Release 5.2(1) switch. Similar configurations must be performed on other switches.

   > router bgp 65535 no synchronization
