OSPF vs IS-IS vs PrivateAS eBGP
by Clue Store 12 Sep '09

12 Sep '09

Hi All, I know this has been discussed probably many times on this list, but I was looking for some specifics about what others are doing in the following situations. I would like to run an IGP (currently OSPF) to our customers that are multi-homed in a non-mpls environment. They are multi-homed with small prefixes that are swipped from my ARIN allocations. OSPF has been flaky at best under certain conditions and I am thinking of making the move to IS-IS. I have also seen others going to private AS and running eBGP. This seems a bit much, but if it works, i'd make the move to it as I like bgp the most (all of the BGP knobs give me the warm and fuzzies :). I'd also like to see what folks are using in a MPLS network?? OSPFv3 or IS-IS or right to MP-BGP and redist static from the CE to PE??? On and off list are welcome. I'll make a summary after I gather the info. Thanks, Clue

I can tell you one reason IS-IS has been traditionally preferred over OSPFv2 is due to it's use of TLVs, which makes IS-IS highly extensible and easy to support new features. I remember when we first rolled out MPLS code on our core routers at UUnet, support for traffic engineering extensions made it into IS-IS long before OSPFv2 due to the ease with which the developers could augment the protocol. Opaque LSAs in OSPF have made this situation a bit more bearable, but other things like OSPFv2s tight integration and reliance on IPv4 addressing for proper operation cause other issues, therefore support for things like IPv6 requires an updated protocol - OSPFv3. If you are running IPv4 and IPv6 in your network you'll need to run both OSPFv2 and OSPFv3. IS-IS on the other hand, since it is CLNS based and not coupled with IPv4 for transport can support IPv4, IPv6, and whatever new protocol we'll be using whenever we run out of the trillions of IP space that IPv6 will provide. Sorry for the typos and the top-posting, as I'm on my crackberry.

Re: Multi-homed implementation and BGP convergence time

--- Andrew.Claybaugh(a)securian.com wrote: From: Andrew.Claybaugh(a)securian.com own AS number, how much downtime will there be? So far the second ISP has only said that it could be hours for BGP to fully converge. We are looking for more detail about how long the outage will be and how widespread. --------------------------------------------------- 1) Hire someone that has done this before. There're many things to be aware of. 2) Get a different provider. Anyone that said it "could be hours for BGP to fully converge" is misleading you. Especially, if you're a new customer to them. That's a bad omen for things to come. This can be done with very minimal impact. scott

Intelligent network monitoring systems (commercial/open source, what have you)
by Drew Weaver 11 Sep '09

11 Sep '09

Howdy, Can anyone suggest a network monitoring system that knows the difference between a cisco 1701 and a GSR 12810/6500, etc? What I mean is, many times these days there are several different sub systems you have to monitor inside of a router/switch and not just interface utilization, the "CPU", and the "RAM". Statistics such as CEF utilization, fabric utilization, PFC/DFC, various line card statistics, etc? Can anyone recommend anything other than "customize MRTG a lot" that we can use to get a better look into these systems? thanks, -Drew

Network Ring
by ty chan 11 Sep '09

11 Sep '09

Dear all, I am in process of planning ring network to cover 15 POPs in City. Some technologies are chosen for consideration like SDH(Huawei), PVRST+(Cisco), RSTP(Zyxel), EAPS (extreme network) and MPLS(VPLS). The purpose is to provide L2 Ethernet connectivities from POPs to central point (DC) and ring protection. I know you all are in those network for years. can you give me some advises? Best regards, chanty
