If you both reference a routing policy and use the command peer { ipv6-group-name | ipv6-address } 

preferred-value value to set a preferred value for routes from a peer, the routing policy sets a non-zero 

preferred value for routes matching it. Other routes not matching the routing policy uses the value set 

with the command. If the preferred value in the routing policy is zero, the routes matching it will also use 

the value set with the command. For information about using a routing policy to set a preferred value, 

refer to the command peer  { group-name | ipv4-address | ipv6-address }  route-policy 

route-policy-name { import | export } in this document, and the command apply preferred-value 

preferred-value in Routing Policy Commands of the IP Routing Volume. 

# Configure the preferred value as 50 for routes from peer 1:2::3:4.

ipv6-group-name: Name of a peer group, a string of 1 to 47 characters. 

ipv6-address: IPv6 address of a peer. 

Use the peer public-as-only command to configure IPv6 BGP updates to a peer/peer group to not 

carry private AS numbers.  

Use the undo peer public-as-only command to allow IPv6 BGP updates to a peer/peer group to carry 

private AS numbers. 

By default, BGP updates carry the private AS number. 

The command does not take effect if the BGP update has both the public AS number and private AS 

number. The range of private AS number is from 64512 to 65535.  

# Configure BGP updates sent to the peer 1:2::3:4 to not carry private AS numbers.
