I am not able to grasp my head around the concept of why PIM Register mechanism is required.
Everyone seems to keep repeating the process of how PIM Register works instead of explaining why its in place.
As I understand it, RP is required to disc...
I am trying to understand the purpose of the mpls mtu interface level command. I do understand it sets the maximum size of an MPLS labeled IP packet that can pass through the interface without fragmentation.
But why would it need to be set as such? W...
I have couple questions regarding a BGP full mesh topology. Please refer to the diagram below. Each depicted link on routers R1 to R4 in AS 100 only is actually a port-channel of two physical 10G links.
The questions I have are as follows:
Scenario ...
Why a new protocol such as BFD is required to detect subsecond failures within routing domains and HSRP setup? Why couldn't the implementation in IOS of existing protocols such as HSRP, EIGRP, BGP and OSPF be modified to allow new subsecond hold or d...
Hello, I have a VPN router that I am using to connect to a remote peer 3.3.3.3 and passing subnet 192.168.10.0/24 NAT'ed to 192.168.126.0/24 through the crypto ACL encryption domain.The remote subnet is 10.192.0.0/12 and when sending packets from 192...
Thanks for that information, makes sense, so the RP simply forwards/steers the original IP packet from the source through the PIM tunnel towards the next PIM neighbor downstream keeping the source IP address within the packet unchanged. The downstrea...
Thanks, that kind of makes sense. So the PIM register process is required so that RP can know about the source of traffic because there is no other automatic discovery of sources from the RP perspective? (kind of odd and weird because from downstream...
However, if its full mesh iBGP between the AS100 and no maximum-paths command configured, would the total throughput now be only 20G?
Edit: you already answered that, thank you very much for your detailed response!
Updated diagram:
I updated the original post when there is iBGP full mesh between all four routers in AS 100 and no maximum-paths command configured under BGP under any of the four routers.
Do you agree that it would be 320G maximum possible throughput only when no ...
Thanks for your response.
I have a couple of follow up questions:
1. Why would BGP use only one link per router? Are you saying that unless the "maximum-paths 4" command is configured under the BGP process on each router, BGP would only select one ...
