Enabling The Bgp Orf Capability - HP 6125G Configuration Manual

Configuring automatic soft-reset
After route refresh is enabled for peers and a policy is modified, the router advertises a route-refresh
message to the peers, which then resend their routing information to the router. After receiving the routing
information, the router performs dynamic route update by using the new policy.
To enable BGP route refresh for a peer or peer group:
Step
1. Enter system view.
2. Enter BGP view.
3. Enable BGP route refresh for a peer or
peer group.
Configuring 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.
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.
Following these steps to save all route updates from a peer or peer group:
Step
1. Enter system view.
2. Enter BGP view.
3. Disable BGP route-refresh and
multi-protocol extension capability for
a peer or peer group.
4. Save all routes from a peer or peer
group.
5. Return to user view.
6. Perform manual soft reset on BGP
connections.

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,
