Disabling BGP routing policies from automatically taking effect
During BGP network optimization or upgrade, each change of BGP routing policies triggers route
refreshing, which burdens BGP routers and the network.
This task disables the policies from automatically taking effect. After modifying all policies, execute the
refresh bgp or reset bgp command to make the new polices take effect.
The following shows BGP routing policies:
• peer as-path-acl
• peer filter-policy
• peer ip-prefix
• peer route-policy
• filter-policy export
• filter-policy import
• peer default-route-advertise
• rr-filter (see MPLS Command Reference)
• peer upe route-policy (see MPLS Command Reference)
To disable BGP routing policies from automatically taking effect:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Enter BGP view.
bgp as-number N/A
3. Disable BGP routing policies
from automatically taking
effect.
undo auto-refresh enable
By default, when a BGP routing
policy is changed, BGP
automatically uses the new policy
to filter the incoming/outgoing
routes.
Configuring a large scale BGP network
In a large-scale BGP network, configuration and maintenance might become difficult due to large
numbers of BGP peers. To facilitate configuration, you can configure peer group, community, route
reflector, or confederation as needed. For information about configuring a peer group, see "Configuring
a B
GP peer group."
