Handling Process

A:
Configure several IP address pools in domain peshb.yn and allocate the IP addresses to be assigned to users to these IP address pools. Then configure multiple L2TP groups and virtual templates. Bind the virtual templates to each IP address pool.
For example (at the side of LNS):

domain peshb.yn
scheme radius-scheme remote
accounting optional
ip pool 0 10.188.144.1 10.188.147.255
ip pool 1 10.188.148.1 10.188.151.255
ip pool 2 10.188.152.1 10.188.155.255
ip pool 3 10.188.156.1 10.188.159.254
ip pool 4 10.188.160.1 10.188.163.254
ip pool 5 10.188.164.1 10.188.167.254
ip pool 6 10.188.168.1 10.188.171.254
ip pool 7 10.188.172.1 10.188.175.254
