protocol pipe and bgp

[Eugene M. Zheganin]

Hello,

If I have pipe between two kernel routing tables, which, in turn, are 
filled with two different BGP protocols, when these routes are exported 
from kernel FIB via pipe, do they retain their BGP attributes like BGP 
preference ? Or, if this question is more clear, does the following 
statement for an pipe filter look sane ?


filter exportfib0tofib2 {
     if source = RTS_BGP then {
             print "fib0 to fib2 export: net accepted: ", net;
             bgp_local_pref = 25;
             accept;
     } else {
             print "fib0 to fib2 export: net rejected: ", net;
             reject;
     }
}

or should I operate generifc protocol preference instead ?

I'm asking because I created BGP/PIPE configuration when the last 
established BGP session seems to get the maximum preference when 
exported via pipe, if you know what I mean.


Thanks.

Eugene.
