Step Command Remarks
6. Specify an ACL to filter routes
imported from an IPv6 peer or
peer group.
peer { group-name |
ipv6-address } filter-policy
acl6-number import
Not specified by default.
The IPv6 BGP-VPN instance view
does not support this command.
7. Specify an AS path ACL to
filter routing information
imported from an IPv6 peer or
peer group.
peer { group-name |
ipv6-address } as-path-acl
as-path-acl-number import Not specified by default.
The IPv6 BGP-VPN instance view
does not support this command.
8. Specify an IPv6 prefix list to
filter routing information
imported from an IPv6 peer or
peer group.
peer { group-name |
ipv6-address } ipv6-prefix
ipv6-prefix-name import
Not specified by default.
The IPv6 BGP-VPN instance view
does not support this command.
9. Specify the upper limit of
prefixes allowed to receive
from an IPv6 peer or peer
group.
peer { group-name |
ipv6-address } route-limit limit
[ percentage ]
Optional.
Unlimited by default.
The IPv6 BGP-VPN instance view
does not support the group-name
argument.
Ignoring the ORIGINATOR_ID attribute of IPv6 BGP routes
In general, IPv6 BGP saves the ORIGINATOR ID attribute of IPv6 BGP routes received from the router
reflector to make sure that those routes will not be advertised back to the route reflector. But IPv6 BGP
might need to advertise BGP-VPN routes with different Route Distinguisher (RD) attributes back to the
route reflector. For more information about RD, see MPLS Configuration Guide. To meet this requirement,
use the peer ignore-originated command to ignore the ORIGINATOR_ID attribute of IPv6 BGP routes
received from the route reflector.
Before you execute the peer ignore-originatorid command, make sure that no routing loop exits among
route reflectors in the network.
The peer ignore-originatorid also enables IPv6 BGP to ignore the CLUSTER_LIST attribute of IPv6 BGP
routes.
To ignore the ORIGINATOR_ID attribute of IPv6 BGP routes:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter IPv6 BGP view. bgp as-number N/A
3. Enter IPv6 address family
view.
ipv6-family N/A
4. Ignore the ORIGINATOR_ID
attribute of IPv6 BGP routes
received from the route
reflector.
peer { group-name |
ipv6-address }
ignore-originatorid
By default, IPv6 BGP saves the
ORIGINATOR ID attribute of IPv6 received
BGP routes.
