[Sysname-bgp] peer 131.108.1.1 as-number 100
[Sysname-bgp] ipv4-family multicast
[Sysname-bgp-af-mul] peer 131.108.1.1 enable
[Sysname-bgp-af-mul] peer 131.108.1.1 preferred-value 50
peer public-as-only (MBGP address family view)

Description
Use
peer
public-as-only
to not keep private AS numbers in BGP updates sent to a peer or a peer group.

test
from carrying private
AS numbers.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] group test external
[Sysname-bgp] peer test as-number 200
[Sysname-bgp] ipv4-family multicast
