I asked this question to a couple of folks: "at the current churn rate/ration, at what size doe the FIB need to be before it will not converge?" and got these answers: --------- jabber log --------- a fine question, has been asked many times, and afaik noone has provided any empirically grounded answer. a few realities hinder our ability to answer this question. (1) there are technology factors we can't predict, e.g., moore's law effects on hardware development (2) there are economics and policy and social factors we can't predict, e.g., how much convegence-capable hardware will providers/vendors be able to afford, how those costs will affect consumer prices, how that will affect consumer uptake, network growth, and industry dynamics, how regulation affects all of the above (3) We Don't Have Any Data from providers on the dynamics of BGP and IGP interactions, much less network wide convergence, so the research community can't provide any empirically grounded input into an answer {elided} ------------------------------- & ------ Forwarded Message ------ Date: Tue, 07 Aug 2007 To: bmanning(a)karoshi.com Subject: CPU Usage Router Upstream Uptime BGP cpu per 1 sec uptime Cat6500/SUP720 1 >1yr 53ms/sec C7200/NPE-G1 1 158days 15ms/sec C7304/NSE100 4+2 177days 55ms/sec C7200/NPE-G1 1+2 26days 8ms/sec C7301 1 214days 7ms/sec GR2000 0+1 101days 6ms/sec Upstream: M+N, M is # of EBGP with full route feed , N is # of IBGP with full route feed Provided if the CPU consumption is propotional to the routing table size, the hard limit would be 10 times to the current size, allowing other tasks to obtain some CPU cycles. ----- End forwarded message ----- so, one might presume that w/o a change in algorithm, and unlimited memory, that the CPU would run out of cycles to compute convergence at ~ 10x the current size of the routing table (abt 250,000 prefixes). so putting a stake in the ground, BGP will stop working @ around 2,500,000 routes - can't converge... regardless of IPv4 or IPv6. unless the CPU's change or the convergence algorithm changes. --bill

For example if the ISP can find out what applications is the host running etc. would it be useful for the ISPs? ------------------------------------------------- No, there're too many free tools that're way fun and good. For example: www.ntop.org with lsof for your particular question. But, you're asking folks who aren't afraid of the technology.

Redistribute routes from EIGRP into BGP VRF
by Bailey Stephen 09 Aug '07

09 Aug '07

Hello all, Currently working on a solution at the moment where I receive specific /25 routes via a leased line into the global routing table via EIGRP on a Cisco 2801. I then need to inject these routes into a BGP VRF to be advertised onto BGP Peers within the VRF Network. The /24 routes for the Site LAN are injected via Radius on the DSL Routers so this task makes the /25 more favourable via the Leased Line Router. ================================================== IOS Version on 2801 (Router B) = Version 12.4(12a) BGP VRF Config: router bgp 65xxx no synchronization no bgp log-neighbor-changes bgp scan-time 10 no auto-summary ! address-family ipv4 vrf test1 redistribute connected redistribute static redistribute eigrp ... ================================================== Simple Diagram attached Routers C & D do not see the redistributed routes from Router B via BGP. Not sure if this is an IOS Bug, but this should work?? Thanks Stephen Bailey
