F3726, F3211, F3174, R5135, R3816-HP Firewalls and UTM Devices Network Management Command Reference-6PW100

860
Parameters
ebgp: Configures load balancing for IPv6 EBGP routes.
ibgp: Configures load balancing for IPv6 IBGP routes.
number: Specifies the number of BGP ECMP routes, in the range of 1 to 8. When it is set to 1, load
balancing is disabled.
The following matrix shows the value range for the number argument on different firewalls and UTM
devices:
Hardware Value ran
g
e
F1000-A-EI/F1000-S-EI 1 to 8
F1000-E 1 to 8
F5000 1 to 16
Firewall module 1 to 8
U200-A 1 to 8
U200-S Incompatible
Usage guidelines
Unlike IGP, BGP has no explicit metric for making load balancing decision. Instead, it implements load
balancing by defining its routing rule.
If you do not provide the ibgp or the ebgp keyword, this command configures load balancing for all IPv6
BGP routes.
After you execute the balance ibgp number or the balance ebgp number command, the balance number
command cannot be executed. To execute the balance number command, you must first use the undo
form of the balance ibgp number or balance ebgp number command to remove the former configuration.
Examples
# Set the number of IPv6 BGP ECMP routes to 2.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] ipv6-family
[Sysname-bgp-af-ipv6] balance 2
# Set the number of IPv6 IBGP ECMP routes to 2.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] ipv6-family
[Sysname-bgp-af-ipv6] balance ibgp 2
# Set the number of IPv6 EBGP routes to 2.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] ipv6-family
[Sysname-bgp-af-ipv6] balance ebgp 2
