What is considered "directly connected customer" in case of BGP?
Let say R1 is receiving some prefixes from 2 nbrs:
1.1.1.1 AS path= 254 100 200 300
2.2.2.2 AS path= 254 50
Let say we wanna only allow AS 254 and its directly connected customers
- does it mean that it should
be only 1 AS behind 254 (like 1 hop)?
I see examples permitting ^254(_[0-9])*$ which is not correct IMO as it
will allow any numbers of ASs
behind 254.
