Service; Configuring A Route Reflector - Juniper J2300 User Manual

Table 126: Configuring IBGP Peering Sessions
Task
Navigate to the Bgp level in the
configuration hierarchy.
Create the BGP group internal-peers,
and add the internal neighbor addresses
to the group.
You must configure a full IBGP mesh,
which requires that each peer be
configured with every other internal
peer as a BGP neighbor.
Set the group type to internal.
Configure a routing policy to advertise
BGP routes.

Configuring a Route Reflector

Because of the IBGP full-mesh requirement, most networks use route reflectors
to simplify configuration. Using a route reflector, you group routers into clusters,
which are identified by numeric identifiers unique to the AS. Within the cluster,
you must configure a BGP session from a single router (the route reflector) to each
internal peer. With this configuration, the IBGP full-mesh requirement is met.
NOTE: You must have an Advanced BGP Feature license installed on each Services
Router that uses a route reflector. For license details, see "Managing J-series
Licenses" on page 69.
To check the configuration, see "Verifying a BGP Configuration" on
page 344.
J-Web Configuration Editor
In the configuration editor hierarchy,
select Protocols>Bgp.
1. In the Group box, click Add new
entry.
2. In the Group name box, type the
name of the group of internal BGP
peers—internal-peers in this case.
3.
In the Neighbor box, click Add new
entry.
4.
In the Address box, type the IP
address of an internal BGP peer, in
dotted decimal notation.
5. Click OK.
6.
Repeat Step 3 and Step 4 for
each internal BGP peer within the
network.
1. From the Type drop-down menu,
select internal.
2. Click OK.
See "Injecting OSPF Routes into the BGP Routing Table" on page 380.
