Configuring BGP load balancing

1. Enter system view.

system-view

N/A

2. Enter BGP IPv4 unicast address family view, BGP-VPN IPv4 unicast address family view, or BGP IPv4 multicast address family view.

• Enter BGP IPv4 unicast address family view:

  1. bgp as-number [ instance instance-name ]

  2. address-family ipv4 [ unicast ]

• Enter BGP-VPN IPv4 unicast address family view:

  1. bgp as-number [ instance instance-name ]

  2. ip vpn-instance vpn-instance-name

  3. address-family ipv4 [ unicast ]

• Enter BGP IPv4 multicast address family view:

  1. bgp as-number [ instance instance-name ]

  2. address-family ipv4 multicast

N/A

3. Specify the maximum number of BGP ECMP routes for load balancing.

balance [ ebgp | eibgp | ibgp ] number

By default, load balancing is disabled.

4. (Optional.) Enable BGP to ignore the AS_PATH attribute when it implements load balancing.

balance as-path-neglect

By default, BGP does not ignore the AS_PATH attribute when it implements load balancing.

5. (Optional.) Enable load balancing for routes that have different AS_PATH attributes of the same length.

balance as-path-relax

By default, BGP cannot perform load balancing for routes that have different AS_PATH attributes of the same length.

1. Enter system view.

system-view

N/A

2. Enter BGP IPv6 unicast address family view, BGP-VPN IPv6 unicast address family view, or BGP IPv6 multicast address family view.

• Enter BGP IPv6 unicast address family view:

  1. bgp as-number [ instance instance-name ]

  2. address-family ipv6 [ unicast ]

• Enter BGP-VPN IPv6 unicast address family view:

  1. bgp as-number [ instance instance-name ]

  2. ip vpn-instance vpn-instance-name

  3. address-family ipv6 [ unicast ]

• Enter BGP IPv6 multicast address family view:

  1. bgp as-number [ instance instance-name ]

  2. address-family ipv6 multicast
