Hello, <br>
<br>
We're trying to implement in our RS configuration
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
additional "Collector" table.<br>
<br>
After making the changes began to generate the following message to
our log file <br>
like this and our log file become too large for a very short time :<br>
<br>
17-12-2012 13:57:16 <ERR> Pipe collision detected when sending
120.28.62.0/24 to table Collector<br>

<br>
Also we observe that this generating message caused our processor to
load significantly.<br>
<br>
Such message is generated of each received prefixes. In this
particular lab we have only one established BGP session<br>
and other 10-11 neighbors not active.<br>
<br>
Everything other works fine. We would like to understand if there is
something wrong in our configuration?<br>
<br>
Here is the configuration which we generated for each new BGP
session:<br>
<br>
table T65050<br>
<br>
protocol pipe P65050 from PIPES {<br>
description "PINGER_PIT";<br>
peer table T65050; <br>
export where bgp_out(65050);<br>
}<br>
<br>
protocol pipe C65050 from PIPES {<br>
description "PINGER_PIT";<br>
table Collector;<br>
peer table T65050;<br>
export none;<br>
}<br>
<br>
protocol bgp R0_149 from PEERS {<br>
description "0.149_PINGER_PIT";<br>
neighbor 193.218.0.149 as 65050;<br>
import where bgp_in(65050);<br>
route limit 320000;<br>
table T65050;<br>
} <br>
<br>
<br>
<b>Global configuration:</b><br>
<br>
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
table Collector;<br>
<br>
# Protocol templates<br>
<br>
template bgp PEERS {<br>
local as myas;<br>
import all;<br>
export all;<br>
route limit 10000;<br>
rs client;<br>
passive on;<br>
prefer older on;<br>
}<br>
<br>
template pipe PIPES {<br>
table master;<br>
mode transparent;<br>
}<br>
<br>
<br>
Thanks in advance!<br>
<br>
Best~<br>
