To do… 

Use the command… 

Remarks 

Enable IPv6 BGP route refresh 
for a peer/peer group 

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

Optional 

Enabled by default 

 

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 ipv6 multicast command to soft-reset 

IPv6 MBGP connections to refresh the IPv6 MBGP routing table and apply the new policy without 

tearing down IPv6 MBGP connections. 

Follow these steps to perform a manual soft-reset

Keep all routes from a 
peer/peer group regardless of 
whether they pass the inbound 
filtering policy

Optional 

 

The BGP Outbound Route Filter (ORF) feature allows a BGP speaker to send to 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, thus 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 (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 IPv6 MBGP ORF capability:
