Honestly, I am not entirely sure whether you can find it on the DocCD. That's one of those things that you are "expected to know", similarly to the contents of RFC1918. What Proctor can help you with is rounding. For example, you may go and I ask if it was OK to round STM-4 to exactly 622.000 Kb/s, instead using the exact value (which, admittedly, I do not know). > - Sometimes, of iBGP, if the loopback is learnt by IGP, we will get RIB > failure, and we can still advertise to peer AS. > r>i125.125.125.2/32 125.125.125.2 0 100 0 ? <<<<< at > first r > Is it ok to leave this rib failure as such? Yes, that simply means that prefix in question was not installed into RIB from BGP, but from another source. However, there is one thing to be careful about here. If you are asked not to have those prefixes in IGP, this could be an indicator that you didn't do that bit correctly and that prefixes are carried in IGP. > - For 'mpls ldp router-id', is it better to use 'force' even though the > question didn't mentions. I would feel comfortable using "force", unless lab asks you not to (unlikely). -- Marko Milivojevic - CCIE #18427 Senior Technical Instructor - IPexpert Mailto: [email protected] Telephone: +1.810.326.1444 Fax: +1.810.454.0130 Community: http://www.ipexpert.com/communities _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com
