Hi Group,
I have the following simple multicast scenario:
R3 (s0/0) -------Frame relay------- (s0/0.134 mp) R4 (Fa0/0)
|
|
|
|
Frame relay
|
|
|
|
R1 (s0/0/0.134 mp)
Details:
- The interfaces are sparse mode.
- R1 joins multicast group 228.34.28.100 on its Fa0/0 interface. R4 is the
RP for this group.
- RP discovery uses Bootstrap protocol. R3 is the BSR.
- The "ip pim nbma-mode" command is prohibited on R3. To work around, a GRE
tunnel is built between R1 & R4 with PIM sparse mode enabled.
The task is to configure the network so that R1 responds to ICMP echo
requests sent to 228.34.28.100 coming from R4's Fa0/0 interface.
Assuming everything is configured correctly, I'd like to know how to test
it. Should I do extended ping as follows?
R4#pi
Protocol [ip]:
Target IP address: 228.34.28.100
Repeat count [1]:
Datagram size [100]:
Timeout in seconds [2]:
Extended commands [n]: y
Interface [All]: <Which interface??>
Time to live [255]:
Source address: <R4's Fa0/0 ip address>
Type of service [0]:
.
.
What interface should I specify?
Or should I just do "pi 228.34.28.100 so fa0/0"? Any difference?
Appreciate any help.
Thank you.
BR,
Emil
