David,
It is the old way of doing prefix lists
Acc 100 permit host 172.16.4.0 host 255.255.255.0
Is the same as:
Ip prefix-list TEST 172.16.4.0/24

Subject: IS-IS route leaking question
Hello everybody,
When configuring IS-IS route leaking you need to use the following
command:
redistribute isis ip level-2 into level-1 distribute-list <100-199>
and an extended IP ACL.
In this extended IP ACL you establish:
Source address: route to be redistributed from Level-2 to Level-1
Destination address: ??????
I have reviewed the following link looking for an answer:
http://www.cisco.com/en/US/tech/tk365/tk381/technologies_tech_note09186a
0080093f39.shtml
but it doesn't offer any example. IE workbook uses "host 255.255.255.0"
as a
destination and it works. I have also tried "any" as destination address
and
it works too for the topology i'm working on. If i try a random network
address it doesn't work, so the destination address should be relevant.
What i want to know is:
1- Which is the purpose of the destination address in the ACL?
2- Why using 255.255.255.0 as destination address the route leaking
works?
Thanks for the help
