Our customer of Company E , has two NE40E version V6R1C02 , working as RR Routers for all BGP Domain , he found that the two RR are client to each other and he thinks this is not necessary , can we delete this configuration and is it going to affect the service ?
For RR rule :
1.If the two RR are in the same cluster , they has no need to be RR clients to other .
2.If they are in different cluster , they has to be Clients to each other.
i.e. RR will reflect routes to clients. If RR-A configure RR-B as client, then RR-B will receive duplicated routes from RR-A. Actually this is waste of bandwidth and performance of router but will not affect the service normally BUT is will helps if there is bad design exists , for example : adding new Router to the network and add the new router to the RR-A only , although this is a bad design but it will be helpful when RR-A send this new route to RR-B .
It is recommended to make RR Client relationship between the two RR , although it is not necessary but it is recommmended .
