Is it normal to see a path as such in my BGP update ?
12 34 33 2 2 45 331
As I can see from the path above, AS number "2" appears twice ! Is it normal ? Are they any scenarios that could have made this to happen ? Is it an anomaly ? If it's like that, how does routing occur after a packet has reached AS 2 ? will AS 2 forward the traffic to itself again prior sending to 45 ?
