Hi Song,
that's normal. This is a signat to AS702 to do some special with this
route when it will see this route.
Community is transistive by its design, so you don't need to be directly
connected to AS702 to send some signal to it.
For example:
you-AS101-AS102-AS103-target

hrm, it's possible that cleaning the communities (after dealing with
the local/customer-added ones) means you
2914:429 is a community to signal to NTT to not announce the route to peers

it looks like this is the 'customer' of several networks (701, 2914)
and they just
Also note there is nothing stopping anyone from adding any community
they want.
The effect and how long the community stays attached to a route is
another matter.

Because there is no standard syntax on the description of BGP community,
I think the problem is hard to understand.

Hi everyone,
Today when I check one route in Routeviews I find something strange as

bgp communities are transitive attributes, e.g. you can just pass them
to peers unmolested. so someone that's presumably not ntt ( e.g. the
neighbor is digital ocean) is sending that commmunity to route views as
