What is it significant to? It is possible to have a router be a part of multiple separate OSPF networks. The process ID is simply a way to distinguish between them within the router's config.

I picked up 4 3550's 24port and 2 2950's 24port for around $150 total locally. 3560 (non-G) are nice Layer 3 switches that should be able to be found cheaply.

No, the process ID indicates two completely separate OSPF clouds. Think VRFs. For example, ports Gig0/1 & Gig0/2 could be assigned to OSPF process 1 and exchange one set of LSAs with neighbors, and ports Gig0/3 & Gig0/4 could be on OSPF process 2 and have a completely separate set of LSAs to exchange with neighbors on those ports. Both OSPF processes can be assigned to the backbone area, but it would be two completely separate backbone areas.

Zuhzuhzombie!! posted:Sorry, but I'm still confused! So... would it be more like running multiple instances of EIGPR via multiple AS numbers? Not really. Each EIGRP instance is analogous to an OSPF area. Read up on VRF for a use-case where you'd run multiple OSPF processes, or VRF-Lite if you don't want to get too deep into MPLS. The gist is that you can have multiple discrete routing tables coexisting in a single router, and each OSPF instance operates on a single routing table. Say that you're running a service provider backbone network, and you have a client who wants a Layer 3 (routed) VPN between their multiple sites. They run OSPF internally and use 10.0.0.0/8. You already run OSPF on your routers, and also use 10.0.0.0/8, so you don't want your routes distributed into the client's network or vice-versa. The solution is to assign the client-facing interfaces to a VRF (separate routing table) and set up a second OSPF process on your routers to peer with their routers and use the client VRF. That way, their routing table is propagated between their sites over your network, while your routing table remains isolated from theirs.

Does anyone know of any good way to calculate bandwidth requirements for many online services? There is no baseline we can go by, company would start off with 20k OWA users, thousands of servers/workstations utilizing backup over the WAN, CRM, Webhosting and BES. I'm guestimating 3Gb based on past experience but I don't think I can present it that way.

Maybe you could recommend going with a Metro Ethernet provider who can do a 10Gbps loop and instant-scalable bandwidth. Then you can start at, say, 2Gbps and turn it up if that turns out to be insufficient.

Great idea about metro ethernet, but I still need to figure out these bandwidth estimates. I'm gonna try and get all the vendor information and reach out to them, maybe they have some stuff to provide.

Inside/Outside Global/Localcode:IP on the inside host is Inside Local and is a private address. IP on the outbound facing interface on R1 facing R2 is a public IP and is the Outside Local. Corresponding IP on the R1 facing interface on R2 is a public IP and is Outside Global. Host behind R2 is Outside Local. Is this correct?

inside local = untranslated source address inside global = untranslated destination address outside local = translated source address outside global = translated destination address from the perspective of an individual router with interfaces considered 'inside' or 'outside'. It's dumb, bad, terrible terminology that Cisco desperately needs to stop using.

Whenever I took a CCNP exam I noticed on the Cisco portal that it moved up my CCNA expiration date to match when I passed the last CCNP exam. If you're already expired (sounds like you are) you probably won't re-up any of the certs that were expired.

Of course I was hot and heavy having just gotten my CCNP back when it was 4 Tests, BSCI, BCMSN, oh right ISCW and the ONT. Yeah, I started on the NP way back when it was that way as well, but never finished and have only kept my NA valid since by passing CCDA for giggles. My attempt in May is really just to see how much I remember and if I want to really push for it. I've transitioned most of our core and edge to Juniper, and the only real Cisco I have left is some access/distro switching, but nothing on the routing side. Once I got in JUNOS I kind of swore off IOS. I'm just worried that I'll walk in May and somehow pass because of sheer luck and then I'm somewhat forced to get ready for the lab, or at least attempt it within 12mths. I think the process is still the same though, pass written, 12mths to take lab, if you fail lab, you get another 18mths. If you fail 2nd time you have to take written again. 1000101 posted:Whenever I took a CCNP exam I noticed on the Cisco portal that it moved up my CCNA expiration date to match when I passed the last CCNP exam. How I understand it to be (I've been helping my guys research training for the year): It is a flat 3yr term for the total certification once earned. I use to think that while doing the CCNP, you could pass one exam a year and practically get the NP over the course of 3 years, but I thought I read in this thread you now have to pass all 3 within a year. You have to take an exam higher than or equal to the certification you hold to keep it current. So for CCNA, you could take any CCNA sub-domain to renew (I used the CCDA to renew my CCNA) or you could take any of the professional level exams. You could re-up your CCNA by passing one(1) of the CCNP exams at the end of your three(3) term for CCNA and it will renew or even just take the CCIE Written, which would renew a CCNA and your CCNP if you had it. http://www.cisco.com/web/learning/certifications/associate/ccna/recert.html - that is specific to CCNA, but it is pretty much the same for each level. Pass the current exam again or something another level above. http://www.cisco.com/web/learning/certifications/professional/ccnp/recert.html - CCNP if needed.

I've been kind of moving into a VMware direction with my career so I'm up in the air about whether I want to follow down the CCNP path now. I guess I have until January to decide, that's when my NA expires. I might do something like CCNA Security just to keep it active though. It'd be a shame to let it expire.
