3. Configure the SoO attribute
for a peer or peer group.
peer
{ group-name | ipv4-address
[ mask-length ] }
soo
site-of-origin
By default, no SoO attribute is
configured for a peer or peer
group.
To configure the SoO attribute (IPv6 unicast/multicast address family):
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:
a. bgp as-number
[ instance
instance-name ]
b. address-family ipv6
[ unicast ]
• Enter BGP-VPN IPv6 unicast
address family view:
c. bgp as-number
[ instance
instance-name ]
d. ip vpn-instance
vpn-instance-name
e. address-family ipv6
[ unicast ]
• Enter BGP IPv6 multicast
address family view:
f. bgp as-number
[ instance
instance-name ]
g. address-family ipv6

Tuning and optimizing BGP networks
This section describes how to tune and optimize BGP networks.
Configuring the keepalive interval and hold time
BGP sends keepalive messages regularly to keep the BGP session between two routers.
If a router receives no keepalive or update message from a peer within the hold time, it tears down
the session.
You can configure the keepalive interval and hold time globally or for a peer or peer group. The
individual settings take precedence over the global settings.
The actual keepalive interval and hold time are determined as follows:
If the hold time settings on the local and peer routers are different, the smaller setting is used. If
the hold time is 0, BGP does not send keepalive messages to its peers and never tears down
the session.
