Command Remarks
2. Enter BGP view. bgp as-number N/A
3. Enter IPv6 MBGP address
family view.
ipv6-family multicast N/A
4. Configure the router as the
next hop of routes sent to the
peer or the peer group.
peer { ipv6-group-name |
ipv6-address } next-hop-local
Optional.
By default, IPv6 MBGP specifies
the local router as the next hop for
routes sent to an EBGP peer or a
peer group, but not for routes sent
to an IBGP peer or a peer group.

Command Remarks
1. Enter system view.

N/A
2. Enter BGP view.
bgp as-number N/A
3. Enter IPv6 MBGP address
family view.
ipv6-family multicast N/A
4. Allow the local AS number to
appear in the as-path of
routes from a peer or a peer
group and specify the number
of times that the local AS
number can appear in the
as-path of routes from the peer
or the peer group.
peer { ipv6-group-name |
ipv6-address } allow-as-loop
[ number ]
Optional.
Not allowed by default.
5. Disable IPv6 MBGP from
considering the AS_PATH
during best route selection.
bestroute as-path-neglect
Optional.
Enabled by default.
6. Configure updates to a peer
or a peer group to carry only
the public AS number.
peer { ipv6-group-name |
ipv6-address } public-as-only
Optional.
By default, outbound IPv6 MBGP
updates can carry private AS
numbers.
Tuning and optimizing IPv6 MBGP networks
Configuration prerequisites
Before you tune and optimize an OSPF network, complete the following tasks:
• Enable IPv6.
• Configure basic IPv6 MBGP functions.
