I am a newbie on this forum and this is the first topic I post, hope I can get help from someone who is warmhearted
I am preparing CCIE R&S exame, I have met a problem configuring access-list , here is an example from the material
Router bgp 3 network 172.16.1.0 mask 255.255.255.0 Neighbor 192.168.5.2 remote-as 1 Neighbor 192.168.5.2 route-map SETCOMMUNITY out
route-map SETCOMMUNITY permit 10 mat ip address 101
access-list 101 permit ip 172.16.0.0 0.0.255.255 host 255.255.0.0
The explanation for the last access-list was this is to match network172.16.0.0 only, in another word, it excludes other entries starts with 172.16
I am confused by the "host 255.255.0.0" used in the access-list ? what does it mean ? from what I understand this is like a Mask-wildcard, but it appears at the 'destination-wildcard' position in the extended-ACL .
Can somebody help me on this ?
