H3 multicast variation

[toronto]

my friend took exam last week and failed H3, he said with me the multicast was changed. the output was looked like that

R13#show ip pim rp mapping
PIM Group-to-RP Mappings

Group(s) 239.250.0.0/16
RP 10.250.250.250 (DC1-RP), v2v1
Info source: 10.1.113.2 (?), elected via Auto-RP
Uptime: 00:21:44, expires: 00:02:02

What do you think about this output?

Thank, I tested and it works for me.

at that time as I know, there were many H3 variations from Cisco. Depends on the location you will take your exam, my friend took exam in HongKong, he got H3 and he said with me in R14, R15 Cisco did not give him the nat pool, but in other location some guys reported he got NAT Pool in R14 and R15. It made me so confused about H3. If we can have a topic about H3, and discuss about it, I think we will have a best solution.

[IEcollection]

I will start a topic about H3 variation today. we will try to solve every case in H3.

Nat Pool : R14 & R15, R24 & R25
Multicast another variation :

SW100#show ip pim rp mapping

How should we do to match this output?
SW100#show ip pim rp mapping
PIM Group-to-RP Mappings
This system is an RP (Auto-RP)
This system is an RP-mapping agent
Group(s) 239.250.0.0/16 RP 10.250.250.250 (DC1-RP), v2v1

[ccierscisco]

this we can achieve from ip pim auto-rp mapping-agent command but I have not tried ..Dont have image. With L2IRON man this command is not supporting.

ip pim auto-rp mapping-agent
To configure the router as an IPv4 Protocol Independent Multicast (PIM) Auto-RP mapping agent that sends RP-Discovery messages, use the ip pim auto-rp mapping-agent command. To remove the mapping agent configuration, use the no form of this command.

Do you know how can we do to implement the RP name lookup one with a name 10.250.250.250(DC1-RP),but another without a name 10.250.250.250(?)

I dont know ..

I dont know ..

I will start solution about H3 today and let you know.

[Nexus]

I updated the solution H3 in this link, you can download it

**Hidden Content: Check the thread to see hidden data.**

[yiya]

In this solution,it still can't match the cisco require multicast output

[Robin]

In this solution,it still can't match the cisco require multicast output

we are waiting a full solution from Nexus about H3 :)

Hi guys,

Thanks for the solution of Section 2.10

Anybody has the solution of Section 2.11?

Many thanks.

Hi guys,

Thanks for the solution of Section 2.10

Anybody has the solution of Section 2.11?

Many thanks.

That is my solution of section 2.11:

[sanritzsanritz]

personally I found, there is a problem in the solution suggested. Nowhere it is mentioned how the RP of the HQ(10.3.250.250) will communicate with RP of DC1(10.250.250.250). I used msdp inter-as peering between them and got expected result.
But I am not sure about the mapping-agent command and how it will work ?

The link is dead, can you reupload?

Can anybody upload the file again please ?
