Enabling The Mbgp Orf Capability - HP A6600 Configuration Manual

Soft reset through route-refresh
If the peer is enabled with route-refresh, when the MBGP route selection policy is modified on a router,
the router advertises a route-refresh message to its MBGP peers, which resend their routing information to
the router after receiving the message. Therefore, the local router can perform dynamic route update and
apply the new policy without terminating MBGP connections.
To do...
1. Enter system view.
2. Enter BGP view.
3. Enable BGP route refresh for a
peer/peer group.
Perform a manual soft reset
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 do...
1. Enter system view.
2. Enter BGP view.
3. Disable BGP route-refresh and
multi-protocol extensions for a
peer/peer group.
4. Enter IPv4 MBGP address
family view.
5. Keep all original routes from a
peer/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 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, thus reducing the number of exchanged update messages and saving
network resources.
After you enable the ORF capability, the local MBGP router negotiates the ORF capability with the MBGP
peer through Open messages. That is, the MBGP router determines whether to carry ORF information in
messages, and if yes, whether to carry non-standard ORF information in the packets. After completing the
