Action Communities

Action communities allow customers to perform traffic engineering without IP Transit NOC involvement. If you need any help using these communities please contact our NOC.


Blackhole Community

The following community is used to blackhole specific IP addresses. We only allow /32 prefix announcements to be blackholed.

ActionCommunity
Blackhole (/32 prefix)64098:666

Action Community Format

AS64098 standard action communities are formatted as our ASN followed by a 4 digit action code. The only exception to this is our blackhole community.

The community string is formatted as follows:

FieldValue
ASN64098
Action Field (64098:Xxxx)Action to take
Peer Type Field (64098:xXxx)Peer types to act upon
Continent Field (64098:xxXx)Continent to apply action
Region Field (64098:xxxX)Region to apply action

Field Value Options

The following values can be used to build a complete action community string.

Note: localpref values can not be targeted and should use a peer type, continent and region value of 0.

Information Communities

Information communities show where and how a prefix was learned and are useful for filtering and analysis of routing issues.


Information Community Format

Our information communities are structured in a similar manner to our action communities except they have 5 digits instead of 4.

The information community strings are formatted as follows:

FieldValue
ASN64098
Peer Type (64098:Xxxxx)Peer type prefix learned from
Continent (64098:xXxxx)Continent prefix learned in
Region (64098:xxXxx)Region prefix learned in
POP (64098:xxxXX)POP prefix learned in

Field Value Options

The following values can be used to decode a complete information community string.
