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? --- On Thu, 7/9/09, Carlos Valero <[email protected]> wrote: From: Carlos Valero <[email protected]> Subject: Re: [OSL | CCIE_RS] Vol 3, Lab 2, Task 5.1 (Multicast) To: [email protected], "Joe Astorino" <[email protected]> Date: Thursday, July 9, 2009, 7:26 PM 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 :-( --- On Wed, 7/8/09, Joe Astorino <[email protected]> wrote: -----Inline Attachment Follows----- _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com
