Enabling the IPv6 MBGP ORF capability
The BGP Outbound Route Filter (ORF) feature enables a BGP speaker to send a set of ORFs to its BGP
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 BGP speaker, thus reducing the number of exchanged update
messages and saving network resources.
After you enable the ORF capability, the local BGP router negotiates the ORF capability with the BGP
peer through open messages. That is, the 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 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
Table 31 .
To enable the IPv6 MBGP ORF capability:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter BGP view. bgp as-number N/A
3. Enter IPv6 address family
view.
ipv6-family N/A
4. Enable BGP route refresh for a
peer or a peer group.
peer { group-name | ipv6-address }
capability-advertise route-refresh
Optional.
Enabled by default.
If this feature is not enabled,
you must configure this
command.
5. Enable the non-standard ORF
capability for a BGP peer or a
peer group.
peer { group-name | ipv6-address }
capability-advertise orf non-standard
Optional.
By default, standard BGP
ORF capability defined in
RFC 5291 and RFC 5292 is
supported.
If this feature is not enabled,
you must configure this
command.
6. Enter IPv6 MBGP address
family view.
ipv6-family multicast N/A
7. Enable the ORF IP prefix
negotiation capability for a
BGP peer or a peer group.
peer { group-name | ipv6-address }
capability-advertise orf ip-prefix { both
| receive | send }
Not enabled by default.
