Hi List,
maybe i'm doing something wrong, but if i use some quick and dirty
filter on the CLI all is working as expecting:
show route where bgp_large_community ~ [(65000, 0, 1001)]
show route where (65000, 0, 1001) ~ bgp_large_community
both get the expected results, show all routes with the specific
community attached.
If i use it in a filter function to filter the routes out:
function filter_large(int TestID)
{
if ( bgp_large_community ~ [(65000, 0, TestID)] ) then { return false; }
return true;
}
i get "all" routes, if clause doesn't get catched.
function filter_large_V2(int TestID)
{
if ( (65000, 0, TestID) ~ bgp_large_community ) then { return false; }
return true;
}
with the V2 function i get what i want, filter out all routes with the
community attached and show all the rest.
I'm a little confused here, because the first version of the if clause is
used for bgp_ext_community on several functions on my setup and working
as expected, only for bgp_large_community i need to switch to if clause
from version V2, and only in a function?
Can someone confirm or explain this?
regards,
tim
