hi ,
i want to ask about estimating the leases duration from router when artributes of IP are given to router from radius .
assume the AAA is from radius server , and im jusing virtual template interface that gives the users an ips .
now assume if from radusi we gave the user x an attribute :
ip:addr-pool=pool1
note that the user x will have an ip from router <pool1 >
but im facing a problem which is , if the user get an ip z.z.z.z from pool1 , and disconnected , then connected and so on , it will always get the same ip which is z.z.z.z
my problem in another way , if i gave a user an attribute to get its ip from router pool , it will seems as im giving that user a fixed ip !!!!!!!
my request is , how to solve this issue and how to define a leased duration to the users when they get an ips from router pools .
i will paste simple config which has relatinion to my question
