Too CPU load on Cisco 7206 VXR for BGP update

Hi,

I have a Cisco 7206 VXR linked to two peer and it have a bgp table with 186000 routes learned from these peers.

The CPU load reaches the 99% (5 sec) and I can understand that's the BGP scanner process reaches these picks.

I would like to know how can I do to eliminate these picks?

Thanks

Regards.

Paolo

Re: Too CPU load on Cisco 7206 VXR for BGP update

Hi,

BGP scanner and BGP router will consume all free CPU cycles. This is the way it is designed.

The only way to reduce the CPU load would be to reduce the BGP table size, but I would assume this is not your intention as it conflicts with redundancy requirements.

So this reflects normal behaviour and as long as average CPU load is not above about 40% there should be no problems.

Are there any problems related to CPU load or why do you want to get rid of those peaks?

Re: Too CPU load on Cisco 7206 VXR for BGP update

Hi,

thank you for your post.

Yes, I want to reduce these picks. Is there a way?

By the way, I would implement a BGP load balancing on two links because one peer have a minor cost respect to the other peer.

I try and use bgp communities for this end.Is there another method?

Regards,Paolo
