After you enable the BGP ORF capability, the local BGP router negotiates the ORF capability with the 

BGP peer through Open messages (that is, determine whether to carry ORF information in messages; 

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, refer to 

. 

Follow these steps to enable the BGP ORF capability:  

Enter system view 

— 

Enter BGP view 

bgp as-number 

Required 

Enter IPv6 address family view 

— 

Enable BGP route refresh for a 
peer/peer group 

peer { group-name | 
ipv6-address } 
capability-advertise 
route-refresh 

Required 

Enabled by default 

Enable the non-standard ORF 
capability for a BGP peer/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.  

Enable the ORF IP prefix 
negotiation capability for a BGP 
peer/peer group 

peer { group-name | ip-address 
| ipv6-address } 
capability-advertise orf 
ip-prefix { both | receive | 
send } 

Required 

Not supported by default 

 

Table 1-1 Description of the both, send, and receive parameters and the negotiation result 

send 

The ORF sending capability is enabled locally 
and the ORF receiving capability is enabled on 
the peer. 

receive 

The ORF receiving capability is enabled 
locally and the ORF sending capability is 
enabled on the peer. 

both 

Both the ORF sending and receiving 
capabilities are enabled locally and on the 
peer, respectively. 

 

Follow these steps to configure the maximum number of load balanced routes:
