[nsp] Max eBGP sessions

[Jim Devane]

All,

Wow. I am glad I asked! 

This is what I needed to know. 
Thank you one and all for your responses! I will try out a few config's
and use the very good advice of peer-groups.

Hi Jim,

Although I have not seen this, I have been told by Cisco that a 7206
w/NPE-G1 and with 512Megs total, and 16Megs left, running 12.1(14)E, the
G1
can do about 1000 peers with about 80k routes.  The 7505 RSP-8 with
256Megs
total and 16Megs left, running 12.0(22)S can do 800 peers with a total
of
80k routes.  When you start to increase the number of routes, those
numbers
drop significantly.  For instance on the RSP-8, with 130k routes, you
can
only do ~450 peers

Hope this helps.


Thanks,

All,
 
I am trying to get a handle on a maximum number of eBGP sessions that
would be possible. Of course, I understand this depends widely on what
platform so I will throw 2 out there a 7507/RSP-8 256 Mb and 7204
VXR/NPE-G1 As far as routes, only doing a minimum, pushing a default
route out and accepting 1 /24 back in. Clearly, this is a hypothetical
exercise but I am trying to validate some suspicions.
 
Again, I am only trying to get a ballpark figure to see if it matches
with what I have in my head already. I am thinking the most would
probably be about 40. 
 
Is there a way that I could stretch this? Is 40 too low? Too high? I am
thinking that I would run into a barrier on the CPU rather than memory.
 
Can someone point me to a resource or call upon experience to help me
get a handle on this?
 
 
TIA,
Jim
