Route Reflector Client#
Virtual Networks → RRRoute Reflector Clients
BGP route reflector clients peer with route reflectors to eliminate the need for a full-mesh iBGP peering network, where every router needs to establish an iBGP session with every other router in the network. They assume that all routes in the network are advertised by the route reflectors.
EDA creates a derived BGPPeer for every RouteReflector that the RouteReflectorClient targets. This targeting is done by assigning labels to the RouteReflector and referencing this label in the RouteReflectorClient.
Don't forget to use labels!
If no target label is specified in the RouteReflectorSelector property of the RouteReflectorClient resource, the RouteReflectorClient will create BGPPeer resources for every DefaultRouteReflector and RouteReflector.
Example:
RouteReflectorClientClient1 has noRouteReflectorSelectorlabelsRouteReflectorClientClient2 has oneRouteReflectorSelectorlabel:my-rr-label=ARouteReflectorRR1 has one label:my-rr-label=ARouteReflectorRR2 has one label:my-rr-label=B
In this example, Client1 will create 2 derived BGPPeer resources: one for each route reflector. Client2 will create only 1 derived BGPPeer resource towards RR1. RR2 does not have label my-rr-label=A, and therefore is not selected as route reflector for Client2.
Dependencies#
To configure this resource, the following resources must exist or be created alongside the RouteReflectorClient
- A
BGPGroupthat theRouteReflectorClientwill inherit settings from, such as local and remote AS numbers - An interface that the
RouteReflectorClientwill use to establish the client sessions. This can either be aRoutedInterfaceor anIRBInterface
Referenced resources#
BGPGroup#
The BGPPeer resource that the RouteReflectorClient creates towards each selected RouteReflector is always linked to a single BGPGroup. These BGP peers share common parameters, such as BGP import and export policies, local and peer autonomous system numbers, and BGP timers. By specifying these parameters in a BGPGroup, the operator can change these settings in a single location for all BGP peers.
RoutedInterface#
To know which IP address the router uses to send BGP traffic, EDA must have a reference to a virtual interface. If this interface is a RoutedInterface attached directly to an Interface, a reference to this resource needs to be provided when creating the RouteReflectorClient.
IRBInterface#
To know which IP address the router uses to send BGP traffic, EDA must have a reference to a virtual interface. If this interface is an IRBInterface attached to a BridgeDomain, a reference to this resource needs to be provided when creating the RouteReflectorClient.
Policy#
The BGPPeer resources that the RouteReflectorClient creates towards each selected RouteReflector inherit import/export policies from the assigned BGPGroup. This behavior can be overridden by specifying policies in the RouteReflectorClient. Click here for more information on BGP import/export policies.

RouteReflectorClient
SPEC
RouteReflectorClient manages the configuration of iBGP sessions between a client and RouteReflectors. This resource allows you to specify the Interface for BGP sessions, set selectors for RouteReflectors, and configure common BGP settings.

default: 0range: 0 to 255 -
Options for removing private AS numbers (2-byte and 4-byte) from the advertised AS path towards all peers.
-
If set to true then do not delete or replace a private AS number that is the same as the peer AS number.
default: false -
If set to true then only delete or replace private AS numbers that appear before the first occurrence of a non-private ASN in the sequence of most recent ASNs in the AS path.
default: false -
The method by which private AS numbers are removed from the advertised AS_PATH attribute.
