Hello everyone,
Today, I'm going to give you a related topic about route reflectors.
Topic
In the network, two devices are prepared to be used as RR devices. There are two problems with RR devices:
1. For RR equipment, please state the two most critical performance indicators you think? And give the reasons.
2. For RR devices, are there requirements for the specifications of the interface board? Do you think you need a lower specification or a higher specification, please explain the reason.
Question1
1. CPU processing capability.
2. Routing table entry carrying capability.
Reason: The RR needs to receive and transmit a large number of BGP routes. Because the BGP protocol only reflects the best routes, it needs to perform a large number of route selection judgments, which requires high CPU processing capabilities.
RR carries a large amount of routing information. All clients/non-clients/EBGP neighbors need to reflect or transmit routing information through RR, which requires high specifications for routing table entries.
Question2
Select the interface board specifications based on whether the RR forwards service traffic.
If the RR is responsible for maintaining and transmitting BGP routes and forwarding service traffic, select an interface board with high specifications. If the RR is responsible for maintaining and transmitting BGP routes but does not need to forward service packets, you can select an LPU with low specifications.
That is all I want to share with you!
