This will remove Router A as the originator of the prefix
an make it "look" as if Router C** ownes the prefix.

**This should read Router B - sorry for the mis-type

Use the following on Router B:

aggregate-address 150.50.31.0 255.255.255.0 summary-only

This will remove Router A as the originator of the prefix
an make it "look" as if Router C ownes the prefix.

Subject: GBP Question

I have a question about filtering BGP As number in AS path table.

Router A has a ip address 150.50.31.1/24 distributed in bgp AS100. In
Router C bgp table, you will see the 150.50.31.0 network as-path is "200
100". My question is how to config bgp in router B to filtering as path
number 100. So router C will
only 150.50.31.0 network as-path is "200"?

 ------------ ------------ ------------
 | Router A |------------| Router B |--------------| Router C |
 | AS 100 | | AS 200 | | AS 300 |
 ------------ ------------ ------------
 150.50.31.1/24
