OpenBGPd max-prefix

could I have reached 10 announced prefixes ? What I imagine is that for a few seconds I did announce all the routes I received from my customer before the max-prefix did cut the session ? Would this be possible that max-prefix is not synchronously checked ? BR, -- Sylvain COUTANT ADVISEO

Re: OpenBGPd max-prefix

well, your 2 plus the 5 from your other customers plus the $max-prefix The 5 is the $max_prefix. We have just only one BGP customer. Total is 7. I should never have announced more than 7 routes in any case. -- Sylvain COUTANT ADVISEO http://www.adviseo.fr/ http://www.open-sp.fr/ Tel: +33

OpenBGP nexthop

was declared invalid, routes to this AS were not installed. I think this could have created a loop : our upstream provider was sending packets for this customer's routes. As we hadn't routes installed for customer's prefix, we were sending back the packets to upstream ... BR, -- Sylvain COUTANT

CPU usage monitoring

Hi all, Is there any way to monitor CPU usage (preference through snmp) on an OpenBSD box ? LoadAverage is reported through netsnmp, but this does not report real CPU usage. As a newbie, I didn't find an easy way to do this. Thanks for tips. BR, -- Sylvain COUTANT ADVISEO http

pf/carp load balancing on 4 firewalls

, how will spanning tree handle this case with the same MAC announced from the 4 firewalls ? My guess is packets from SRV1 will be dispatched to FW1* because the cost will be lower. Same for SRV2/FW2*. Could some help me understand how this setup could behave in real ... BR, -- Sylvain COUTANT

Re: pf/carp load balancing on 4 firewalls

local as possible. If you have a relationship with the vendor, ask them. Not still sure of the vendor. Should be 3COM. Or simply try it out and report back! I don't have the hardware, I must plan this for the end of the month. BR, -- Sylvain COUTANT ADVISEO http://www.adviseo.fr/ http

will be the memory overhead ? Currently my memory load goes up every hour (between 1 and 2 MB per hour). Will this stop at some point and how could try to approximate the final load ? Thanks for your help. BR, -- Sylvain COUTANT ADVISEO http://www.adviseo.fr/ http://www.open-sp.fr/

OpenBGP Communities manipulations

Re: OpenBGP Communities manipulations

There is a feature in 3.8 that let you only set one community per AS. This is fixed in -current. OK. BTW, how one could remove community tags ? BR, -- Sylvain COUTANT ADVISEO http://www.adviseo.fr/ http://www.open-sp.fr/
