[isp-bgp] Questions about a Cisco 6509

[Jeff Crowe <listacct@...]

Hi all,

I have charged with updating our network architecture.  We have decided
to go with Cisco as our router/switching.

My understanding so far of the 6500 is it is a switch until you add the
Supervisor card  (WS-X6K-SUP1A-2GE).  Will the  WS-X6K-SUP1A-2GE card
does BGP itself, or do I need a daughter card of some sort? 

Also, how much memory should I have for the 3 full BGP feeds?  I have
read that Cisco recommends 128MB per BGP feed, but I have also heard
murmers that the 128 MB will soon be inadequate due to the global
routing size.  So with 512MB, would there be enough memory left over to
service the router's requirements while holding the 3 BGP feeds? 

The reason for the 6509 is we would be amalgamating our existing 2924's
into it, so the switching functions are required.

Here is the configuration that I have come up with from the Cisco
configurator.  With my requirements above, will this suite my needs? 

WS-CDC-2500W  Catalyst 6000 2500W DC Power Supply    
WS-CAC-2500W/2  Catalyst 6000 Second 2500W AC Power 

SC6K-SCVK9-7.6.1  Catalyst 6000 Sup 1 Flash Image w/CV and SSH, Release
7.6.1     1     

MEM-C6K-FLC24M  Catalyst 6000 Supervisor PCMCIA Flash Mem Card, 24MB
Option 

WS-X6K-SUP1A-2GE  Catalyst 6000 Supervisor Engine1A, Enhanced QoS, 2GE 

MEM-C6K-FLC24M  Catalyst 6000 Supervisor PCMCIA Flash Mem Card, 24MB
Option 

WS-X6348-RJ-45  Catalyst 6500 48-port 10/100, Upgradable to Voice, RJ-45
WS-X6348-RJ-45  Catalyst 6500 48-port 10/100, Upgradable to Voice, RJ-45
WS-X6348-RJ-45  Catalyst 6500 48-port 10/100, Upgradable to Voice, RJ-45

Thanks for all the help with this.
