customer traffic engineering (TE) notes
--------------------------------------------------------
1. Communities allow suppress or prepend to peer AS, where
- peer AS has a peering connection to Ucomline,
- peer AS is not a customer of Ucomline.
2. Blackhole implementation.
The customer will need to ask for the "blackhole" feature
to be enabled on their BGP session.
This will enable two sets of prefix filters on the routes
learnt from the customer:
- the normal filter will match exactly the routes registered
in the IRRs,
- the "blackhole" filter will match any host (/32 network),
that is contained within the normal set of routes.
