Internet routes on a 7606

Hi, I have a 7606 router with SUP720-3B. Is there a SUP or RSP I can upgrade to which will support the whole internet's routing table, and how much memory upgrade will I need? I'm also having issues with fragmentation of GRE tunnels to the router. I know the SUP720-3Bs are known to have issues with this. Is there a workarround?

Hello,

upgrade to WS-SUP720-3BXL or better

We have two of them receving two full BGP tables and they work well

6 2 Supervisor Engine 720 (Active) WS-SUP720-3BXL SAL10467RED

and for BGP prefixes:

34028 32279 102076074 0 0 1w3d 2913

897030 897148 102076074 0 0 40w5d 1

26002164 897072 102076074 0 0 40w5d 271572

26115413 897143 102076074 0 0 40w5d 234211

or better or rsp-720 if you like and you can

it should behave better with GRE

Hope to help

Hello,

we have 1GB on our systems

someone says to count 256 MB for eaxch full table

A device of mine the same of the show in previous post is currently:

sh proc mem | inc Free

Processor Pool Total: 903574352 Used: 407205024 Free: 496369328

I/O Pool Total: 67108864 Used: 14337856 Free: 52771008

Be aware that DFCs have to be able to hold CEF table as resulting of the routing table

so also the memory on DFCs is important

Hope to help

Giuseppe
