Hello, I'm wondering, is there any way to configure following example to single rule only. if bgp_path ~ [= * 100 * =] then return false; if bgp_path ~ [= * 200 * =] then return false; if bgp_path ~ [= * 300 * =] then return false; if bgp_path ~ [= * 400 * =] then return false; On this way, If we want to filter many ASs, it seems that we should generate too much rows. On Cisco we can implement it like following example: AS path access list 85 deny _(100|200|300|400)_ permit .* Thanks in advance!
