Hi Scott,
Could you please shed some light on this issue?
I'm just trying to figure out some details of the following example. It's from
Cisco web site at
http://www.cisco.com/univercd/cc/td/doc/cisintwk/ics/icsbgp4.htm :
############################################
Using access lists to filter supernets is a bit trickier. Assume, for example,
that Router B in
has different subnets of 160.10.x.x, and you want to advertise
160.0.0.0/8 only. The following access list would permit 160.0.0.0/8,
160.0.0.0/9, and so on:
access-list 1 permit 160.0.0.0 0.255.255.255
To restrict the update to 160.0.0.0/8 only, you have to use an extended access
list, such as the following:
access-list 101 permit ip 160.0.0.0 0.255.255.255 255.0.0.0 0.0.0.0
###################################################
Would you please explain what they exactly mean by this solution (bold lines)?
It's not very clear to me especially when it comes to the last ACL (101).
Thanks for any hint.
Cheers,
Kambiz
