Hello All
Kidding purpose email to get some smile
So lessons learned.
(1) Basic knowledge like (highest or lowest priority)
(2) Configuration typo error
(3) Prematured decision
Additional, I may add,
(4) Interactive effect checking.
Just relax

OK, seems like I jumped in a little prematurely here. The ACL is fine and the
priority doesn’t need swapping in your solution below, Carlos (but your
question has a typo). Anyhow, the Solution Guide is being updated correctly and
will be in the members section on our next update cycle.

The ACL is fine. The priority value should be swapped so that it uses 10 on R2
and 20 on R7. This is just another lesson in how CCIE’s can make typo’s. I’m
fixing it up in our Proctor Guide now.

Subject: Re: [OSL | CCIE_RS] Vol 3, Lab 2, Task 5.1 (Multicast)
Made a little mistake on the requirements section.
The second part should be like this:
Configure R7 to announce candidacy as an RP for Groups:
- First octet = 225 or 227
- Second octet less than 128
- Priority = 20
Originally I wrote Priority = 10
But the solution it is being configured with Priority = 10
- ip pim rp-candidate l1 group-list 51 prio 10
That's exactly the source of my confusion.
Why is R7 configuration based on R2's requirements and vice-versa?

Hello,
I think I need some help with this task.
It seems to be quite simple, but to me the solution seems to be backwards and
I'm very confused and stock!
Requirements:
Configure R2 to announce candidacy as an RP for Groups:
- First octet = 225 or 227
- Priority = 10
Configure R7 to announce candidacy as an RP for Groups:
- First octet = 225 or 227
- Second octet less than 128
- Priority = 10
Solution:
R2:
access-list 51 permit 225.0.0.0 0.255.255.255
access-list 51 permit 227.0.0.0 0.255.255.255
ip pim rp-candidate l1 group-list 51 prio 20
ip pim bsr-candidate l1
R7:
access-list 51 permit 225.0.0.0 0.127.255.255
access-list 51 permit 227.0.0.0 0.127.255.255
access-list 51 permit 225.0.0.0 0.127.255.255
access-list 51 permit 227.0.0.0 0.127.255.255
ip pim rp-candidate l1 group-list 51 prio 10
ip pim bsr-candidate l1
This seems to be backwards to me!
That is, the requirements state that R2 should have a Priority = 10 and
R7 should have a Priority = 20
But it is configured backwards! R2 = 20 and R7 = 10!
Needless to say, the ACL also seem to be backwards to me!
Obviously, there is something that I'm missing here.
And frankly I don't know what it is.
I hope somebody can help.
Did I mention that Multicast is my less favorite topic?
Actually I should say that I almost hate it :-(
