NSE4, FortiGate and RPF Checks from www.reddit.com
Without the RPF check, R3 would forward the packet it got from R1 to R2, and vice versa, and begin the process of looping packets also with the same logic, R1 and R2 also keep repeating the process 2) This is confusing: My understand is RP does not perform RPF check on the SRC IP of the encapsulated multicast stream in the Register message but we can see router is performing RPF check on the Register message pay load i,e SRC IP 199.199.199.10
NSE4, FortiGate and RPF Checks
When a multicast packet arrives on an interface, the RPF process checks to ensure that this incoming interface is the outgoing interface used by unicast routing in order to reach the source of the multicast packet This duplication creates multicast routing loops and generates multicast storms that waste bandwidth and router resources. Using the drop count and suppressed drop count statistics, a network administrator can takes steps to isolate the attack at a specific interface.
Top 5 Cisco Softwares That You Must Check Out. Using the drop count and suppressed drop count statistics, a network administrator can takes steps to isolate the attack at a specific interface. I labbed up a simple three router ospf/multicast topology and noticed something confusing for the RPF check
Cisco mtrace command RPF failure YouTube. interface Ethernet0/0 nameif outside security-level 0 ip address x.x.86.2 255.255.2. I thought the RPF check would allow multicast traffic to come in from that source on both interfaces, but it is only allowing it in one.
