Hi,
I am working on Multicast section of Lab2.
-----Serial-R2-(Eth)-------(eth2/0.26)R6(eth2/0.6)
R2 is the RP
R6 is the source for 228.28.28.28
SW1 is the Receiver for multicast. (located behind R2).
Problem:
----------
I am getting an error "RPF failed" ? How to correct this config. I
have configured as in solution. May be i am missing something.
I assume the problem is because when i ping from R6, it considers
source of the ping as Ethernet (ip pim spare-mode) & does not put that
interface in outgoing list.
Rack1R6#ping 228.28.28.28
Type escape sequence to abort.
Sending 1, 100-byte ICMP Echos to 228.28.28.28, timeout is 2 seconds:
*Apr 15 00:57:19.666: IP(0): s=132.1.6.6 (FastEthernet2/0.6)
