DropsySufferer posted:Oh wow this must be dated I've never heard of using an RJ-11 in an RJ-45 jack. Really? I do it all the time. I always tell clients/customers to get three jacks wired with cat5e/cat6 to every station before they move into a suite. That way they can have up to 2 network and a phone at every place without needing to string patch cables over cube walls with mini hubs. And if they don't use POTS phones the network cabling is already done for VOIP or another network device (printer, etc) CrazyLittle fucked around with this message at 19:48 on Jan 12, 2013 |

We're not going to see IPv6 exhuastion... we're just going to see quadrillions of addresses wasted because entire /48 subnets will be relegated down to /126's in pager code. For example, Comcast's anycast DNSv6 IP: 2001:558:FEED::1 Oh, and my shortcut for IPv6 is every group (FFFF) is /16 worth. Just for fun, consider that every two groups is one internet's worth of addresses, and ARIN's default delegation to ISPs is /32, where every ISP customer is supposed to get a /48. code:

DropsySufferer posted:Any good estimate on how long IPv4 will remain the industry standard before IPv6 becomes the new standard? I've heard IPv4 will be the standard for at least another five years or more. As long as it takes for people to ditch their old routers and firewalls. Five years is a modest estimate. I think it will be in wide use in five years, but probably won't overtake IPv4 universally for seven or more years. There are people who are still using IPX/SPX for their LAN protocols. doomisland posted:The best waste is a /64 for a point to point link instead of a /127 Yeah, I forget why but I still use /30 (and /126) for all my point to point links. There was some argument against using a /31 but it probably hinged on compatibility with lovely customer hardware. CrazyLittle fucked around with this message at 20:45 on Jan 23, 2013 |

Don't pay extra for a 1760. There's two advantages to the 1760: 1) faster CPU rated for 8mbps 16kpps (instead of 6mbps 12kpps) 2) internal power supply = no brick. Beyond that they're exactly the same. The two other card slots are VIC-only (no WICs allowed). That means they're only useful on a 1760-V. If you want to get fancy look for a 1721 with 64-128DRAM 32Flash (VPN card optional). Then you can run 12.4 IOS which has "do"... but that can lead to bad habits.

I wouldn't complain if I had to use JunOS. At least with JunOS and Vyatta, your commands aren't immediately applied, so you're less likely to lock yourself out of the router.

BigT posted:I agree with the CCENT, in fact, if i see that or Network+ I dive in. The reason i recommend Net+ over CCNET is because the future is commodity hardware with open source software. Cisco's not losing out due to software, or even the "free"-ness of OSS. Cisco is losing out because their hardware depends on custom ASICs to process all the accelerated functions of their hardware, and today's desktop processors can out-perform ASICS even without hardware acceleration. This resulted in other big name hardware makers like Juniper (and now Brocade/Vyatta) switching over to commodity hardware and multi-processing platforms to curbstomp Cisco's performance with cheaper boxes. You can buy a Ubiquiti-made router running Vyatta with 3 routed gigabit ethernet interfaces in it for $100, and it will beat the performance numbers of $2000 cisco ISR routers. Mind you - that's not really open source software. The big names will have their place at the top of the food chain for the foreseeable future. They offer standardization and support verticals that OSS still doesn't offer, and probably won't any time soon.

Yeah the vmware "class materials" are a joke. The practice tests dive in to stuff that wasn't even remotely mentioned in the class materials, but they require you sit X number of hours in a classroom in order to take the test. IMHO: find the cheapest, fastest means of checking off the class time requirement, and then self-study the rest.
