Configuring Routing Between Pes - HP 12500 Series Configuration Manual

To do...
Configure BGP to filter received
routes
NOTE:
By default, a PE does not advertise routes learned from iBGP peer CEs to iBGP peers, including VPNv4
•
iBGP peers. Only when you configure an iBGP peer CE as a client of the RR, does the PE advertise routes
learned from it to other iBGP peers.
You can execute the reflect between-clients command and the reflector cluster-id command in multiple
•
views, such as BGP-VPN instance view and BGP-VPNv4 subaddress family view. The two commands
take effect for only the RR in the view where they are executed. For RRs in other views, they do not take
effect.
Configuring an RR does not change the next hop of a route. To change the next hop of a route, configure
•
an inbound policy on the receiving side of the route.
Configure the CE
2.
To configure the CE:
To do...
Enter system view
Enter BGP view
Configure the PE as the iBGP peer
Configure route redistribution
NOTE:
• Exchange of BGP routes of a VPN instance is the same as that of ordinary BGP routes.
The BGP configuration task in BGP VPN instance view is the same as that in BGP view. For more

Configuring routing between PEs

Perform the following configurations on PEs.
To configure routing between PEs:
To do...
Enter system view
Enter BGP view
Use the command...
filter-policy { acl-number |
ip-prefix ip-prefix-name } import
Use the command...
system-view
bgp as-number
peer { group-name | ip-address }
as-number as-number
import-route protocol [ process-id ]
[ med med-value | route-policy
route-policy-name ] *
