Can anyone explain me how to troubleshoot and the way to fix the task 4 from Lab 5 on VOl2 ?
The task says:
Routers in AS 200 learn the PIM SM RP information from AS 100.
• Fix this security issue and ensure there is no RP information leaking.
• AS 100 and AS 200 are using the link between SW4 and R4 exclusively for multicast traffic exchange.
The solution would be:
SW4:
interface Fa 0/4
ip pim bsr-border
R1:
interface FastEthernet 0/0
no ip pim sparse-mode
SW1:
interface FastEthernt 0/1
no ip pim sparse-mode
but I really dont understand how to troubleshooting it and why the command ip pim bsr-border should be used to fix that.
I will read more about it and if you can help me I really appreciate it.
thanks a lot.
