Configuring EBGP between MCE and VPN site
To use EBGP for exchanging routing information between an MCE and IPv6 VPN sites, you must
configure a BGP peer for each IPv6 VPN instance on the MCE, and redistribute the IGP routes of each
VPN instance on the IPv6 VPN sites.
If EBGP is used for route exchange, you also can configure filtering policies to filter the received routes
and the routes to be advertised.

Configurations on the MCE
To configure EBGP between MCE and VPN site:

4.
Specify an IPv6 BGP peer in
an AS.

Required
5.
Redistribute remote site routes
advertised by the PE.
import-route protocol [ process-id
[ med med-value | route-policy
route-policy-name ] * ]
By default, No route redistribution
is configured.
6.
Configure a filtering policy to
filter the routes to be
advertised.
filter-policy { acl6-number |
ipv6-prefix ip-prefix-name } export
[ direct | isisv6 process-id | ripng
process-id | static ]
Optional
By default, the MCE does not filter
the routes to be advertised.
7.
Configure a filtering policy to
filter the received routes.
filter-policy { acl6-number |
ipv6-prefix ip-prefix-name } import
Optional
By default, the MCE does not filter
the received routes.
NOTE:
After you configure an IPv6 BGP VPN instance, the IPv6 BGP route exchange for the IPv6 VPN instance is
the same with the normal IPv6 BGP VPN route exchange. For more information about IPv6 BGP, see
Layer
3—IP Routing Configuration Guide.
