Re: [OSL | CCIE_RS] PBR

[Scott Morris]

In the real lab, you MAY find things more clearly pointed out than what the lab here did.   However, in progressing towards your CCIE, you need to begin to realize HOW things work, and when particular options are taken away from you see what other items you have at your disposal that may not be obvious (such as PBR, GRE tunnels, NAT, etc.).   I liken things like this to the CiscoPress book for R&S Labs written by Maurillio Gorito (one of the proctors) where two devices run RIP and you are told to make them use unicast, but do not use the "neighbor" command.  And the solution, while mentally painful, used NAT as the answer in order to translate the multicast packets into unicast ones.   In case it hasn't been obvious already, the CCIE lab is not always about good design decisions!  But working through the how and why things work in order to find a solution that doesn't break any rules.  In the lab this question was originally about (per the PG) the lab designer apparantly saw that as a solution, which it is.  But in reading the lab, they didn't specifically say to NOT use inverse-arp.  Inverse arp is a much simpler solution, although it could lead to some other problems down the road.  You'll need to assess this damage (or not) for yourself in the lab you work in.   But knowing to look for things like that and assess what things could go wrong means you are much closer to passing your lab no matter what seemingly bizzare stuff they throw at you!     Scott Morris, CCIE4 (R&S/ISP-Dial/Security/Service Provider) #4713, JNCIE #153, CISSP, et al.

I mean will the LAB question clearly ask this with the relevant parameters to be configured or indirectly we have to understand this from the question?   Thanks   Jay         Note: This e-mail (including any attachments) is intended only for the recipient(s) named above.
