[nsp] 7500: catos+ios vs ios (Hybrid & Native IOS)

[Everett Dowd]

Our entire core network is using 6509's in native mode. It makes setting up
fairly consistent with the new edge devices and our failover is no more than
about 30 seconds. If you are using a 6509 for special purpose, I would keey
hybrid but if you want to route and switch in a box, then IMHO native is the
way to go. It makes a 65xx almost like a 76xx router. 

All of our 6509's are running very stable and have been for several years We
do have 2xsups1a/msfc1/2 and sup2/msfc2 on our core devices now. You just
can't do too many fancy things and certain cards are not supported in native
versus hybrid. However they rock without many problems...

YMMV

Hello,
Reading this document on cisco's site:
http://www.cisco.com/en/US/products/hw/switches/ps708/products_white_paper09
186a00800c8441.shtml
I can't found out which Hybrid or Native solution is _better_.

I just read somewhere that Hybrid solution is no more developped.
Is is true ?

What about the bugs ? Does Hybrid solution work work fine ?

I have an 6509 with 2xsup1a/pcf/msfc2 with 256ram each.
Running on catos with "system highavailability" when I
reset a sup cart, layer 2 is down 4-5 secondes max. And
I have 2 routers inside 1 box (layer3: ospf/bgp) !! 
That is why I want to use Hybrid solution (even if it is
a little bit more complicated to setup since I have to 
switch betten catos and ios)

Does it make sense to have 2xsup with native ios ? I read
somewhere HSRP is the only solution to have highavailability
with ios and it does not work very well ? Any experiance ?

Thanks for help
Octave
