4 important questions on Foundation Topics - Dense-Mode Routing Protocols - Operation of Protocol Independent Multicast Dense Mode
What does the C and T flag mean?
What is the RPF neighbor?
Which interface is the traffic forwarded?
R3# show ip mroute
(10.1.1.10/32, 226.1.1.1), 00:00:12/00:02:48, flags: CT
Incoming interface: Serial0/1, RPF nbr 10.1.4.1
Outgoing interface list:
FastEthernet0/0, Forward/Dense, 00:00:12/00:00:00
T-flag traffic forwarded on shortest path tree
neighbor 10.1.4.1
forward interface fastethernet 0/0
What is the state of interface serial 0/1? When will the router flood again if no prune message is recieved?
Incoming interface: Serial0/0, RPF nbr 10.1.2.1
Outgoing interface list:
Serial0/1, Prune/Dense, 00:00:08/00:02:52
This means that no traffic is forwarding over serial 0/1
2:52 min/sec
What is default prune timer? What happens when a router does not recieve a prune message?
When prune timer expires traffic will flood again
