IPv6 RA vs DHCPv6 - The chosen one?
by Ravi Duggal 11 Jan '12

11 Jan '12

Hi, IPv6 devices (routers and hosts) can obtain configuration information about default routers, on-link prefixes and addresses from Router Advertisements as defined in Neighbor Discovery. I have been told that in some deployments, there is a strong desire not to use Router Advertisements at all and to perform all configuration via DHCPv6. There are thus similar IETF standards to get everything that you can get from RAs, by using DHCPv6 instead. As a result of this we see new proposals in IETF that try to do similar things by either extending RA mechanisms or by introducing new options in DHCPv6. We thus have draft-droms-dhc-dhcpv6-default-router-00 that extends DHCPv6 to do what RA does. And now, we have draft-bcd-6man-ntp-server-ra-opt-00.txt that extends RA to advertise the NTP information that is currently done via DHCPv6. My question is, that which then is the more preferred option for the operators? Do they prefer extending RA so that the new information loaded on top of the RA messages gets known in the single shot when routers do neighbor discovery. Or do they prefer all the extra information to be learnt via DHCPv6? What are the pros and cons in each approach and when would people favor one over the other? I can see some advantages with the loading information to RA since then one is not dependent on the DHCPv6 server. However, the latter provides its own benefits. Regards, Ravi D.

subnet prefix length > 64 breaks IPv6?
by Glen Kent 07 Jan '12

07 Jan '12

Hi, I am trying to understand why standards say that "using a subnet prefix length other than a /64 will break many features of IPv6, including Neighbor Discovery (ND), Secure Neighbor Discovery (SEND) [RFC3971], .. " [reference RFC 5375] Or "A number of other features currently in development, or being proposed, also rely on /64 subnet prefixes." Is it because the 128 bits are divided into two 64 bit halves, where the latter identifies an Interface ID which is uniquely derived from the 48bit MAC address. I am not sure if this is the reason as this only applies to the link local IP address. One could still assign a global IPv6 address. So, why does basic IPv6 (ND process, etc) break if i use a netmask of say /120? I know that several operators use /120 as a /64 can be quite risky in terms of ND attacks. So, how does that work? I tried googling but couldnt find any references that explain how IPv6 breaks with using a netmask other than 64. Glen

Internet Edge and Defense in Depth
by Holmes,David A 05 Jan '12

05 Jan '12

Some firewall vendors are proposing to collapse all Internet edge functions into a single device (border router, firewall, IPS, caching engine, proxy, etc.). A general Internet edge design principle has been the "defense in depth" concept. Is anyone collapsing all Internet edge functions into one device?

Hi. I have some big goals and a lot of enthusiasm but I need direction. I'm looking for a mentor who can help me focus my career so eventually I wind up working at one of the Tier I ISPs as a senior tech. I want to handle the big pipes that hold everyone's data. This is what I want to do with my life. I have my CCNA, and when I graduate college I'll have a CCNP, and the ability to move anywhere in the USA. Please message me off-list. Thank you, Tyler.

L3 consequences of WLAN offload in cellular networks (was - endless DHCPv6 thread)
by Alexander Harrowell 02 Jan '12

02 Jan '12

In the DHCP v6 thread, there was some discussion of mobility and its IP layer consequences. As various people pointed out, cellular networks basically handle this in the RAN (Radio Access Network) and therefore at layer 2, transparently (well, as much as things ever are) for IP purposes. It therefore shouldn't be a problem. However, as one contributor pointed out, more and more cellular operators are migrating traffic onto WLAN for various reasons, notably: 1) Spectrum - it's unlicensed, i.e. free 2) Capex - the equipment is cheaper 3) Capacity - it's a cheap way of providing high speed 4) Signalling load - it gets rid of the signalling traffic associated with detaching and attaching devices from the core network. This is especially important in view of some smartphones' behaviour. Of course much of the signalling is associated with the Mobility Management features, and getting rid of it by punting everything to WLAN implies that you lose the benefits of this. That suggests that if you're going to do this on a big scale you need to implement Mobile IP or else keep backhauling traffic from the WLAN access points to the cellular core network (GAN/Iu interface), which has obvious effects on the economics of the whole idea. Alternatively, you can work on the assumption that the WLAN is solely for nomadic use rather than true mobility, but a lot of devices will prefer the WLAN whenever possible. Thoughts/experiences? -- The only thing worse than e-mail disclaimers...is people who send e-mail to lists complaining about them

Windows UDP packet generator software?
by Jay Nakamura 31 Dec '11

31 Dec '11

The goal of what I am doing is to test some network convergence impact in a lab with two PCs with windows (Can't run Linux, it would be easier if I could) and switches and/or routers in between. So, I thought there must be some simple utility out there that can just start spewing out UDP packets to the other side at a certain time interval and I can look at packet loss via what arrives on the other side with wireshark on the PC. I found hping but it seems to be outdated and I can't get it to work on my windows boxes. Anyone have any suggestions?
