Configuring an IPv6 BGP route reflector
In general, because the route reflector forwards routing information between clients, you are not required
to make clients of a route reflector fully meshed. If clients are fully meshed, HP recommends disabling
route reflection between clients to reduce routing costs.
If a cluster has multiple route reflectors, you must specify the same cluster ID for these route reflectors to
avoid routing loops.
To configure an IPv6 BGP route reflector:

p
Command Remarks
1. Enter system view.
system-view N/A
2. Enter BGP view.
bgp as-number N/A
3. Enter IPv6 address family
view.
ipv6-family N/A
4. Configure the router as a route
reflector and specify an IPv6
peer or peer group as a client.
peer { ipv6-group-name |
ipv6-address } reflect-client
Not configured by default.
5. Enable route reflection
between clients.
reflect between-clients
Optional.
Enabled by default.
6. Configure the cluster ID of the
route reflector.
reflector cluster-id cluster-id
Optional.
By default, a route reflector uses its
router ID as the cluster ID.
Configuring 6PE
IPv6 provider edge (6PE) is a transition technology with which Internet service providers (ISPs) can use
existing IPv4 backbone networks to provide access capability for sparsely populated IPv6 networks,
allowing customer edge (CE) routers in these isolated IPv6 networks to communicate with IPv4 PE routers.
Work mechanism of 6PE:
IPv6 routing information from users is converted into IPv6 routing information with labels and then
flooded into IPv4 backbone networks of ISPs through BGP sessions. When IPv6 packets are forwarded,
they are labeled when entering tunnels of backbone networks. The tunnels can be GRE tunnels or MPLS
LSPs.
IGPs running on ISP networks can be OSPF or IS-IS. IPv6 static routing, IPv6 IGP, or IPv6 EBGP can be
used between CE and 6PE.
