Unanswered Question
Dec 25th, 2008

Hi, I am confused with Route- Reflector.

I want to know detail about it. Can Client send update to Route Reflector Server? What about non-client ? Please help me.

I have this problem too.

HI Rupesh, [Pls RATE if HELPS]

In general, the Route-Reflector are called as the Server.

The Routers that form neighbourship with the RR are called as Clients.

The Updates are exchanged between the Server & Clients only.

The word "non-client" means, the Router doesnot have session with the Route-Reflector itself.

Kindly add more information to the Question to help further.

Best Regards,

Guru Prasad R

Hello Guru,

>> The word "non-client" means, the Router doesnot have session with the Route-Reflector itself

Actually the meaning is different a non client iBGP neighbor is an iBGP neighbor that has a normal iBGP session with the RRS.

(it is missing the

neigh x.x.x.x route-reflector-client

on the RRS)

This is a legitimate configuration and allows to build a full mesh of RR Servers for example in a service provider network.

The updates received by a RRS are treated differently if arriving from a client or from a non-client:

updates coming from a client are reflected to all other clients and all non clients.

updates coming from a non-client are sent only to clients not to other non clients.

Hope to help

Giuseppe
