-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hi Hank, It is possible for routes to get stuck in the global routing table, although it is pretty rare. The is a project called the BGP Clock, they announce prefixes, then withdraw them, and then check if they are still visible anywhere, to see if the prefixes are "stuck". It's called the BGP Clock because they encode the time in the IPv6 prefix, so each prefix is unique and you can see when it was announced (and thus how long it's been lingering in the DFZ). F5s ASN in one that shows as potentially having this problem according to this tool: https://www.thousandeyes.com/bgp-stuck-route-observatory/?asn=35280 Note that this can't be taken as any sort of guarantee and this is just a "hint" because there are many variables at play. I actually don't know what the "OBSERVED PATHS" is showing here, 35280 doesn't appear in any of them, so are they the paths "up to" 35280 ? With kind regards, James. -----BEGIN PGP SIGNATURE----- Version: ProtonMail wsG5BAEBCgBtBYJpprDmCRCoEx+igX+A+0UUAAAAAAAcACBzYWx0QG5vdGF0 aW9ucy5vcGVucGdwanMub3JnyVYZmSuscCtYL9o+a2kWUxr80kno5he9CLyu 5fHU+YkWIQQ+k2NZBObfK8Tl7sKoEx+igX+A+wAAdwYP/iFT17rN8rjspKHl 8ijluvP50a7inXWhr25tmkiOn1ZKpvYo4OGAbpiB2CQ3s+qS39B1zAozLyFB CtLYLBcd4rSsFh97JDB23PsX6iWCVMpbXpQXWg4bm/3WFE+Eb0JBU4cSHaLT bPqQ7qcL87VgUCO9TA9SiyDyyfKJqoDLWM/UIIfR0mGnEVyVOP2oM79orqlw v1xOsN5T66ApDytRbyAF41Yzzr6djS27IFdKbpgWvxRVGdhbSjbg5yM1azCZ UbgKOm+2LhhCg1nObGUO29zsCMeObC43ka5PS3zKV0C4ZNE3QtuzrZCbBPyj JjT+uiHCgBMEYDx7gdem7h4+PwkroC9fo8TVN1QyxeEWKfgb3dcrmA3IyGzT mhKEv4GXOT8weYg6nQHButZ8SisZjgW2SDltZ/0Ha79y568exDsw2pGQ6TS4 Xr0txoM+DUDefI/4LlLdsWm04o6MSJM9Nlntve41FZPJOXgPfU63XiTW72P0 DjQ4uqHbtnjRpixPpwECuwa0+jv6I750jMC8o/eVjsJYT4Z8dniLFMHDrpge b05YzJAYt5zPGIDp+9lW7aTcb8ZGmklb2XL6t1tl3aHpf+rzTAe/r3uO/4hx zLi4ii/OvOrfamZ7Yjs1IPgo69EzQRbytw0b0G24OQqFMl2CoWFQZVQKdfyd v2ObuYxL =pHnk -----END PGP SIGNATURE----- _______________________________________________ NANOG mailing list https://lists.nanog.org/archives/list/[email protected]/message/CFTB2TRXA7345TJERA35D2XRKVUZOIOV/
