Enabling The Bgp Orf Capability - HP 3600 v2 series Configuration Manual

To do...
Enable BGP route refresh for a peer or peer
group
Configure manual soft-reset
If a BGP peer does not support route-refresh, you must save updates from the peer on the local router by
using the peer keep-all-routes command, and use the refresh bgp command to refresh the BGP routing
table.
Following these steps to save all route updates from a peer or peer group:
To do...
Enter system view
Enter BGP view
Disable BGP route-refresh and multi-protocol
extension capability for a peer or peer
group
Save all routes from a peer or peer group
Return to user view
Perform manual soft reset on BGP
connections
NOTE:
If the BGP peer does not support route-refresh and the peer keep-all-routes command is not configured
for it, you need to decide whether to manually disconnect the peer to learn routes again according to the
impact of the new policy.

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 neighboring relationship, 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
Follow these steps to enable the BGP ORF capability:
