I am trying to filter some BGP updates coming in from an upstream BGP peer and have been reading through this.
http://www.cisco.com/en/US/tech/tk365/technologies_tech_note09186a00801310cb.shtml
My requirement is to deny 10.10.0.0/16 and all subnets coming from the upstream BGP peer and allow everything else.
I have implemented this which seems to do the job
access-list 102 deny ip 10.10.0.0 0.0.255.255 255.255.0.0 0.0.255.255
access-list 102 permit ip any any
router bgp 65001
neighbor 10.10.251.194 distribute-list 102 in
I am just now looking at other ways to do it?
Maybe with a prefix lis?
Does anyone have any input on this method or any other better methods?
Thanks
Roger
