Command Remarks
7. Enable a peer or peer group
for an address family and
enable the exchange of BGP
routing information of the
address family.
peer { group-name | ip-address }
enable
By default, only IPv4 routing
information is exchanged between
BGP peers.
8. Add a peer into an existing
peer group.
peer ip-address group group-name
Optional.
9. Configure the system to use
the local address as the next
hop of a route to be
advertised to a specified peer
or peer group.
peer { group-name | ip-address }
next-hop-local
Optional.
By default, the system uses the local
address as the next hop of a route
to be advertised to an EBGP peer.
In the inter-AS option C solution,
configure the peer { group-name |
ip-address } next-hop-invariable
command on the RR for multi-hop
EBGP neighbors and reflector
clients to make sure the next hop of
a VPN route is not changed.
10. Configure the system to be the
RR and set a peer or peer
group as the client of the RR.
peer { group-name | ip-address }
reflect-client
Optional.
By default, no RR or RR client is
configured.
11. Enable the Outbound Route
Filtering (ORF) capability for a
BGP peer or peer group.
peer { group-name | ip-address }
capability-advertise orf ip-prefix
{ both | receive | send }
Optional.
By default, the ORF capability is
disabled on a BGP peer or peer
group.
12. Enable route target filtering
for received VPNv4 routes.
policy vpn-target
Optional.
Enabled by default.
13. Enable route reflection
between clients.
reflect between-clients
Optional.
Enabled by default.
14. Specify the cluster ID of the
RR.
reflector cluster-id { cluster-id |
ip-address }
Optional.
Router ID of an RR in the cluster by
default.
15. Create an RR reflection policy.
rr-filter
extended-community-list-number
Optional.
By default, an RR does not filter the
reflected routes.
With an RR reflection policy, only
IBGP routes whose Extended
Communities attribute matches the
specified one are reflected.
By configuring different RR
reflection policies on different RRs,
you can implement load balancing
among the RRs.
