Topic: Inter-AS BGP Local Preference Matrix
by Rettke, Brian 31 Oct '10

31 Oct '10

My company is building a national backbone network, leveraging leased lines and dark fiber from Tier 1/2/3 providers. What we've found is that when we buy IP in the major markets, our traffic does not flow deterministically with AS-Path as the metric. This is because most of the major providers give their customers one local preference value, and their peers another, in an effort to ensure SLAs are met by keeping customer traffic on-net for as long as possible. There are varying values assigned, and some vendors don't offer community values to neutralize this effect. I'm wondering if anyone has dealt with this in the past, or if it would be possible to have some sort of agreement on local preference manipulation. Something similar to the below: 1. All vendors must offer at least 5 community values for local preference. This is to allow for customer-based multivendor traffic engineering. 2. All vendors must offer a local preference community value greater than their best default metric. 3. All vendors must offer a local preference community value lesser than their worst default metric. 4. All vendors should offer a range of community values both above and below local preference 100. 5. All vendors should make an effort to standardize the values/value ranges offered with other vendors. 6. All vendors should offer a local preference matrix to their customers, listing the changes made to a specific AS (e.g. another vendor) to aid the customer in making an intelligent routing decision for load balancing and traffic engineering in a multivendor BGP environment. It's obviously something that each of us would need to do individually, but I'm wondering if there is any way this could become a de facto standard, or could be a method that the community at large could enforce somehow.

Route hijacking
by Geoff Huston 30 Oct '10

30 Oct '10

My bgp monitor tells me: *> 1.2.3.0/24 203.119.76.3 0 4608 1221 4637 3561 1299 12025 ? *> 5.4.3.0/24 202.12.28.1 0 4777 2516 1239 1299 12025 ? These are _not_ authorized announcements, so could AS3561 Savvis AS1299 Telia AS1239 Sprintlink kindly DROP these unauthorized route advertisements (and clean up their route acceptance processes so that they stop announcing unauthorized noise to the rest of the Internet). And could the folk who run AS12025 IO-DATA-CENTERS - IO Data Centers kindly stop route hijacking? thanks, Geoff

IPv6 Routing table will be bloated?
by Jack Bates 30 Oct '10

30 Oct '10

So, the best that I can tell (still not through debating with RIR), the IPv6 routing table will see lots of bloat. Here's my reasoning so far: 1) RIR (ARIN in this case, don't know other RIR interpretations) only does initial assignments to barely cover the minimum. If you need more due to routing, you'll need to provide every pop, counts per pop, etc, to show how v6 will require more than just the minimums (full routing plan and customer counts to justify routing plan). HD-Ratio has NO bearing on initial allocation, and while policy dictates that it doesn't matter how an ISP assigns to customer so long as HD-Ratio is met, that is not the case when providing justification for the initial allocation. 2) Subsequent requests only double in size according to policy (so just keep going back over and over since HD is met immediately due to the minimalist initial assignment?) So I conclude that since I get a bare minimum, I can only assign a bare minimum. Since everything is quickly maxed out, I must request more (but only double), which in turn I can assign, but my customer assignments (Telcos/ISPs in this case) will be non-contiguous due to the limited available space I have to hand out. This will lead to IGP bloat, and in cases of multi-homed customers whom I provide address space for, BGP bloat. I'm small, so my bloat factor is small, but I can quickly see this developing exactly as my v4 network did (if it was years ago when I first got my v4 allocation, growing to today, for each allocation I got for v4, I'd expect similar out of v6). Sure, the end user gets loads of space with those nice /48's, but the space within ISPs and their ISP customers is force limited by initial allocations which will create fragmentation of address space. This is brought about due to the dual standard of initial vs subsequent allocations (just enough to cover existing vs HD Ratio). As an example, Using HD-Ratios as an initial assignment metric can warrant a /27, whereas the minimalist approach may only warrant a heavily utilized /30. 3 bits doesn't seem like much, but it's a huge difference in growth room. Bare minimums, as provided by me, only included the /24 IPv4 DHCP pools converted with a raw conversion as /32 IPv4 = /48 IPv6 network Am I missing something, or is this minimalist approach going to cause issues in BGP the same as v4 did?

Re: Weird Nexus AD
by Tim Stevenson 30 Oct '10

30 Oct '10

am = adjacency manager. Since NXOS is a modular OS, different processes/services source routes to the URIB, and AM is one of them. OSPF, BGP, other RPs, HSRP, etc also feed their routes to the URIB. AM really only feeds directly connected host prefixes (/32) to the RIB (ie, for each resolved ARP entry). These entries are not shown in sh ip route by default (unless you're running very old code) - I assume you are using sh ip route am to see these? If so, completely expected. We can take the discussion to cisco-nsp or offline if you need more information.

We're seeing an AD of 2 on some routes on our Nexus 7k. I can't find anything (Google) to indicate where this value is coming from. Also unable to find out what "am" mean (adjacency module?).
