Roller Network is Autonomous System 11170.
BGP is supported on both IPv4 and IPv6. Our minimum accepted and carried prefix lengths are /24 in IPv4 and /48 in IPv6. Customer neighbor configurations will have a prefix-list or distribute-list applied to limit announcements into our network; please submit a support request for changes to BGP filters.
We support BGP communities for customers. By tagging your announcements with specific communities you can dynamically change certain BGP parameters within our network.
Setting the Local Preference
Routes learned from customers and peers will have a higher default localpref than all other prefixes. This will prefer directly connected networks those learned externally and takes precedence over AS path prepending. Setting localpref below 100 may cause an externally learned prefix to be chosen.
|11170:90||Set localpref to 90|
|11170:100||Set localpref to 100 (default)|
|11170:110||Set localpref to 110 (peer default)|
|11170:120||Set localpref to 120 (customer default)|
|11170:130||Set localpref to 130|
BGP announcements to peers or transit providers can be suppressed without withdrawing the route completely. The well known community “no-export” is also accepted. One or more of the following communities may be used:
|65100:6939||Do not announce to Hurricane Electric AS6939|
|65100:2914||Do not announce to NTT AS2914|
|65100:0||Do not announce to peers|
|no-export||Do not announce outside of AS11170|
AS Path Prepending
You can prepend your announcements to transit or peers. In all cases, 11170 is the AS prepended.
|11170:401||Prepends transit 1x|
|11170:402||Prepends transit 2x|
|11170:403||Prepends transit 3x|
|11170:411||Prepends peers 1x|
|11170:412||Prepends peers 2x|
|11170:413||Prepends peers 3x|
