Disable Bgp-Igp Route Synchronization; Configuring Bgp Route Dampening - H3C S5600 SERIES Operation Manual

To do...
Filter the
routing
information
received from
a peer/peer
group
Routes received by a BGP router are filtered, and only those matching the specified ACLs are
added to the routing table.
A peer group member and the peer group can use different inbound routing policies, that is, peers
of a peer group can use different route filtering policies for receiving routing information.

Disable BGP-IGP Route Synchronization

Follow these steps to disable BGP-IGP route synchronization:
To do...
Enter system view
Enter BGP view
Disable BGP-IGP route
synchronization
BGP-IGP route synchronization is not supported on the switches.

Configuring BGP Route Dampening

Route dampening is used to solve the problem of route instability. Route instability mainly refers to route
flapping. A route flaps if it appears and disappears repeatedly in the routing table. Route flapping
increases the number of BGP update packets, consumes the bandwidth and CPU time, and even
decreases network performance.
Specify an
ACL-based BGP
route filtering policy
for a peer/peer group
Specify an AS path
ACL-based route
filtering policy for a
peer/peer group
Specify an IP prefix
list-based BGP route
filtering policy for a
peer/peer group
Use the command...
system-view
bgp as-number
undo synchronization
Use the command...
peer { group-name |
ip-address } filter-policy
acl-number import
peer { group-name |
ip-address } as-path-acl
acl-number import
peer { group-name |
ip-address } ip-prefix
ip-prefix-name import
5-20
Remarks
Required
By default, no ACL-based
BGP route filtering policy,
AS path ACL-based BGP
route filtering policy, or IP
prefix list-based BGP
route filtering policy is
configured for a peer/peer
group.
Remarks

—
Required
By default, BGP routes and IGP
routes are not synchronized.
