[c-nsp] Question on 7513 BGP peering series

[Brian Turnbow]

Hi Gordon,
You need to check out the ram on your VIPs as  the full routing table is going to occupy memory on them as well.  
You might consider asking your upstreams if they will give you a partial feed + defaults.
Most providers will do this and it will give you a fairly decent way to balance traffic yet still have full internet access while maintaing your existing hardware. 

Regards
Brian

Subject: [c-nsp] Question on 7513 BGP peering series


Hello,

I am in a dilemma and could really need a bit of advice.

I work in a small data centre with 7513 primary router running IOS 12.2(27)

Using an RSP 8 with 256MB RAM
And PA-A3 OC3 ATM connection on a VIP2-50

Plus numerous internal Ethernet and fast Ethernet connections on VIP2-40 and
VIP2-50

As of today I three BGP peerings over 2 separate vrf(s) - one vrf with 2 BGP
connections, and another with 1 BGP connection. VRFs are configured with
re-distribution.

Also at this time, I only get the default routes from my peers - but to make
full use of my multi-homed infrastructure I need to get the full BGP tables.


Now I do not know if my hardware is capable to work with receiving the full
routes of the Internet (actually three different routes from three different
peers). That is, do I need to upgrade the VIPs? or RSP? or actually I'll be
better off with a new router.

Hopefully there's someone out there who would have worked in a similar
setup.

Thanks

Gordon Bezzina
