Just doing a short blog entry..
This weekend I started on my second pass of Multicast and IPv6. I didn’t spend much time on IPv6…I feel that I am quite solid on this topic at this point. Not really going to speak much on IPv6 ( I may do a separate blog entry for that topic). Get solid on the IPv4 addressing (link-local, ULA, global unicast, EUI-64)and configuration. IPv6 should come naturally from a routing protocol perspective. RIPng, EIGRPv6 and OSPFv3 are similar to its IPv4 older sister. Get used to configuring these protocols at the interface level. If you don’t believe me get your hands on a Nexus switch running NX-OS. It is quite painful to work with NX-OS and then have to go back to IOS. The IGP routing protocols have moved towards interface level configuration. I like the NS-OS. They have a TONS of nice IOS enhancements that we all wish were there with Cisco IOS. Lots of “/” notation…no more 255.255.255.0….just do 1.1.1./24 in your interface configuration!
I did review the Multicast IPv6 portions of the material. There is a good chance that IPv6 PIM BSR might show up on the lab (that’s not a much of news to anyone studying for the CCIE lab because ANYTHING could show up on the exam).
For the most part, I watched the following Multicast INE CoD Videos:
Advanced technologies COD – Multicast Module 7 (7 videos)
Deep Dive – Multicast (20 videos)
In total, I watched 27 videos. The lengths of videos ranged from 30-60 minutes per video. This curriculum was considered as a 3 Day multicast Boot camp. I took me all of Saturday and most of Sunday to get through all the videos. I watched the videos and worked through some of the corresponding labs in Workbook VOL 1. The videos were actually pretty good…Brian McGahan was the trainer for these.
Trouble-shooting Multicast can be quite involved. I plan to do more review on some of the material for the next few days to make sure I am solid by working the remaining VOL 1 labs to fill in any gaps.
Some quick commands for me to remember(if I type them, I will remember them in the future)
ip pim send-rp-announce (for AutoRPconfigure this on the candidate RP)
ip pim send-rp-discovery (for AutoRPconfigure this on the mapping agent)
ip pim rp-address (defines the RP)
ip pm sparse-mode
ip pim dense-mode
ip pim sparse-dense-mode
ip pim nbma-mode (for non broadcast multiaccess interfaces)
sh ip pim neighbor
sh ip pim interface
sh ip pim rp mapping
sh ip mroute
ip mroute (for configuring a static multicast route)
That’s it for now…thanks for reading. SUBSCRIBE!
