No-client-reflect

[ralwarrag]

HI Experts

in which case I will need to configure " no-client-reflect " ,,  As far as I know it's used if the clients are in full mesh and your using it so u will not reflect the same route to it , but if I have full mesh client  at the first place why I am using route reflector and if the RR configured with this knob then what is the use of it ( RR )

Hi,

If u r using full-mesh so no need to use RR. I will give u one scenario to use no-client-reflect when u have more than one client in the group and u don't want to reflect routes to specific neighbor from RR side, you could use this command at neighbor level

HI  Elhariry

Thanks for your reply , this is what I understand but in the Description in the below link it say we use it in case if we have full mesh and RR to prevent sending redundant copy of the updates

Yes that's right (Include this statement when the client cluster is fully meshed) when the client is fully meshed so no need to send route advertisement from RR

Your totally right , that is make me confuse what is the need if already there is RR to configure full mesh and then configure this knob

Good point. This knob would be useful when you are migrating from conventional full mesh BGP peering to RR peering.

Recently i used no-client-reflect for my migration project.

The scenarios is as follows:

1. I have existing network A with 2 RR & 21 RR-Clients routers where most of my customer connected to RR-Client.

2.  I need to migrate all the customers from network A to network B.

3. Network B router running on full-mesh & in order to get the routes from network A i would need a peering session with RR in network A.

4. i configured no-client-reflector on RR to prevent the routing loop &  sending of redundant route advertisements.
