Use Case: ECMP with BGP Routing

Aug 31, 2016

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 
    bgp log-neighbor-changes 
    neighbor 10.100.26.14 remote-as 65535 
    neighbor 10.100.26.15 remote-as 65535
