An administrator is configuring an extended ACL for BGP route selection. Which ACE command should the administrator issue to permit only 192.168.0.x networks with a /24 through /32 prefix length?
- permit ip 192.168.0.0 0.0.0.255 255.255.255.0 0.0.0.255
- permit ip 192.168.0.0 0.0.255.255 255.255.255.0 0.0.0.255
- permit ip 192.168.0.0 0.0.0.255 0.0.0.255 255.255.255.0
- permit ip 192.168.0.0 255.255.255.255 255.255.255.0 0.0.0.255
Explanation: When an ACL is used for BGP network selection the ACE source field matches against the network portion of the network and the destination field matches against the network mask. In this example the ACE source field source and wildcard-mask of 192.168.0.0 0.0.0.255 will match the first 24 bits of network 192.168.0.x. The destination field of 255.255.255.0 0.0.0.255 will match prefix lengths of /24 through /32.
