[j-nsp] Curly braces in AS-path

[Vincent De Keyzer]

Hello all,

the following comes from the TeliaSonera looking glass (http://lg.telia.net/
):

Router: Hong Kong
Command: show route protocol bgp 1.38.0.0/17 table inet.0

inet.0: 518574 destinations, 1103564 routes (518516 active, 113 holddown,
1207 hidden)
+ = Active Route, - = Last Active, * = Both

1.38.0.0/17        *[BGP/170] 1w2d 17:44:34, MED 0, localpref 150
                      AS path: 1273 55410 38266 {38266} ?
                    > to 80.239.130.206 via ge-2/1/1.0

What do the curly braces in the AS path mean? More generally, does someone
know a document explaining how to interpret the output of "sh route prot
bgp"?

Thanks,

Vincent
