According to all of the documentation I've found, the first 2 bytes must be the ASN of the network the community is being sent to. Following what documentation says is not "presumptuous", it's following documentation.

They said 'we don't support communities'; I got the impression they weren't familiar with BGP communities, as it took about six emails to explain it. I was hoping to just try it and see if their network would pass on assigned communities through the advertisements, hoping that other networks might abide by them. -- ----------------------------------------------- - Nick Bright - - Vice President of Technology - - Valnet -=- We Connect You -=- - - Tel 888-332-1616 x 315 / Fax 620-331-0789 - - Web http://www.valnet.net/ - ----------------------------------------------- - Are your files safe? - - Valnet Vault - Secure Cloud Backup - - More information & 30 day free trial at - - http://www.valnet.net/services/valnet-vault - ----------------------------------------------- _______________________________________________ Mikrotik-users mailing list Mikrotik-users@wispa.org http://lists.wispa.org/mailman/listinfo/mikrotik-users
