Configuring Routing Between Pes - HP HSR6800 Configuration Manual

Step
8. Configure BGP to filter
routes to be advertised.
9. Configure BGP to filter
received routes.
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 only on 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.
2. Configure the CE:
Step
1. Enter system view.
2. Enter BGP view.
3. Configure the PE as the
IBGP peer.
4. Configure the route
redistribution and
advertisement behavior.
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 information, see Layer 3—IP Routing Configuration Guide.

Configuring routing between PEs

For information about BGP peer
and BGP peer group
configuration, see Layer 3—IP
Routing Configuration Guide. This
chapter does not differentiate
between peer and peer group.
Optional.
A CE must advertise its routes to
the connected PE so the PE can
advertise them to the peer CE.
