toujours sur la ML zebra :
(un peu long, mais intéressant)

|   Currently we are running a mix of Cisco and gated for our BGP.
| I have decided to remove all Cisco stuff from the BGP speaking.  Cisco
| will only from now on be used to do egress routing to customer sites.  I made
| this decision based on the following criteria, YMMV:
[...]
| 2) Cisco's continuing code bloat on IOS is beginning to obsolete their
| garden variety workhorse BGP router - the 72xx series.  (I consider the 36xx
| series mere toys and am amazed they are still humping that architecture, but
| that's another story)  [...]
| and with the latest 12.1 and 12.2 IOS, it's no longer possible to take more
| than 2 BGP views without the router destabilizing because it runs out of
| ram.  Cisco is| quite obviously aware of the problem but is completely
| uninterested in fixing  it, instead preferring to evangelize about how all
| the PA adapters usable  in the 72xx series can work in the VXR series of
| 72xx which can take 256MB of | ram.
[...]
| 3) Cisco's biggest technical strength in my opinion is their plethora of
| adapter types that will interconnect with everything [...]
| But in the backbone Internet world,
| there's only 5 connection types of any consequence - 
| T1's, E1's, DS3's, OC3's and Fast Ethernet - [...]
| BGP tables are continuing to increase and it doesn't help when bozo's at
| the  major backbones (like Sprint) make mistakes and dump 50K worth of
| internal routes out onto the global BGP tables, which is happening with
| alarming frequency.  But, this is where Cisco devices are weakest.  [...]
| the numbers of PC's produced every year dwarfs the number of Cisco routers,
| and so naturally the R&D that's spent on making PC's go faster by the
| industry is an order of magnitude greater than anything Cisco
| can afford to spend on making Cisco routers go faster. [...]

ensuite :

| The biggest drawbacks I see to using PC's as BGP routers are:
| 1) nonstandardization, The Bus Factor.  Yes, if you build up a BGP
| network with PC's, and get hit by a bus, your successor is probably going
| to come in and go "Oh shit!  I don't know what the hell is going on here!"

et le thread fait encore 2 kilomètres ... à suivre :)
