Hello All,
I had few Questions while doing some hands on in BGP, any info on
the following will be very helpful.
Question 1#
A +-----+
\
B ---- D
/
C +-----+
A is in AS 100
B is in AS 200
C is in AS 300
D is in AS 400
AS-PATH
AS-AGGRE
B is getting route 10.10.1.x from A with AS-PATH 100 110 120 { 1
2 3 }
B is getting route 10.10.2.x from C with AS-PATH 200 110 130 { 1
4 }
When B aggregates the route and send it to D what will be the AS-PATH
and AS-SET Field
Question 2#
Uses the same topology
AS-PATH
AS-AGGRE
B is getting route 10.10.1.x from A with AS-PATH 100 110 120 { 1
2 3 }
B is getting route 10.10.1.x from C with AS-PATH 200 110 130 { 1
4 }
Now For B who will be the best route
Question 3#
Uses the same topology
AS-PATH
AS-AGGRE
B is getting route 10.10.1.x from A with AS-PATH 100 110 120 { 1
2 3 }
B is getting route 10.10.1.x from C with AS-PATH 200 110 {
1 4 5 6 7 8}
Now For B who will be the best route
Thanks
