To do… Use the command… Remarks
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.
Configuring the as_path attribute
Follow these steps to configure the as_path attribute:
To do… Use the command… Remarks
Enter system view system-view —
Enter BGP view bgp as-number —
Enter IPv6 MBGP address family
view
ipv6-family multicast —
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.
Disable IPv6 MBGP from
considering the as_path during
best route selection
bestroute as-path-neglect
Optional
Enabled by default.
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 the IPv6 MBGP basic functions
Configuring IPv6 MBGP soft reset
After you modify a route selection policy, you must reset IPv6 MBGP connections to make the new one
take effect.
The current IPv6 MBGP implementation supports the route-refresh feature that enables dynamic route
refresh without terminating IPv6 MBGP connections.
