I have two routers connecting to two upstream ISP's...(Im an ISP myself) one primary one secondary. The two routers have the exact BGP configuration. i recently configured local preference on the routers with one set to 150 and the other at default 100. now the problem is that the router with pref of 150 (R1) has started advertizing routes which are learned by (R2) how can i stop this? i do not want to advertize these routes. i only want to advertize my routes. my R1 is even getting to 100% cpu due to the same! now when i do a "show ip bgp nei xx.xx.xx.xx advertised-routes" I am advertising so many routes i cant even find the ones I want to advertize only! how can i stop these updates?
