Hi Maria, i think the confusion part is, that it works on CLI in a "symmetric" way but not in a function, that was my biggest questionmark :) regards, tim On Mon, May 15, 2023 at 01:21:46PM +0200, Maria Matejka wrote:
Hello!
The ~ operator is not symmetric. We should probably better check its arguments or maybe even update the syntax. It basically means, when A ~ B, that A is in B.
Sorry for that confusion. Maria

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
