Enabling The Mbgp Orf Capability - HP 6125G Configuration Manual

Step
3. Enable BGP route refresh for a
peer or a peer group.
Performing soft reset manually
If the peer does not support route refresh, you can use the peer keep-all-routes command to save all the
route updates from the peer, and then use the refresh bgp ipv4 multicast command to soft-reset MBGP
connections to refresh the MBGP routing table and apply the new policy without terminating MBGP
connections.
To perform a manual soft reset:
Step
1. Enter system view.
2. Enter BGP view.
3. Disable BGP route refresh and
multiprotocol extensions for a
peer or a peer group.
4. Enter IPv4 MBGP address
family view.
5. Keep all original routes from a
peer or a peer group
regardless of whether they
pass the inbound filtering
policies.
6. Return to user view.
7. Soft-reset MBGP connections
manually.

Enabling the MBGP ORF capability

The MBGP Outbound Router Filter (ORF) feature enables an MBGP speaker to send a set of ORFs to its
MBGP peer through route-refresh messages. The peer then applies the ORFs, in addition to its local
routing policies (if any), to filter updates to the MBGP speaker, reducing 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. That is, the BGP router determines whether to carry ORF information
in messages and, if so, whether to carry nonstandard 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
