Configuring The Interval For Sending The Same Update; Enabling The Bgp Orf Capability - HPE FlexNetwork HSR6800 Configuration Manual

Configuring the interval for sending the same update

A BGP router sends an update message to its peers when a route is changed. If the route changes
frequently, the BGP router sends a large number of updates for the route, which can cause route
flaps. This task allows you to configure the interval for sending the same update to a peer or peer
group, avoiding frequent update sending and route flaps.
To configure the interval for sending the same update to a peer or peer group:

Enabling the BGP ORF capability

The BGP Outbound Route Filtering (ORF) feature allows a BGP speaker to send its BGP peer a set
of ORFs through route-refresh messages. The peer then applies the ORFs—in addition to its local
routing policies (if any)—to filter updates to the BGP speaker, reducing the number of exchanged
Update messages and saving network resources.
After you enable the BGP ORF capability, the local BGP router negotiates the ORF capability with
the BGP peer through Open messages (determines whether to carry ORF information in messages,
and if yes, whether to carry non-standard ORF information in the packets). After completing the
negotiation process and establishing the BGP session, the BGP router and its BGP peer can
exchange ORF information through specific route-refresh messages.
For the parameters configured on both sides for ORF capability negotiation, see

Optional.
By default, the intervals for
sending the same update to an
IBGP peer and an EBGP peer are
15 seconds and 30 seconds,
respectively.
If the interval is set to 0, the same
update is sent to a BGP peer
immediately when a route is
changed.
