Hi, Given a simple scenario for multilink ppp ( 2 links) : 2500 ======== 4500 Configuration (refer to : http://www.cisco.com/warp/public/131/7.html) Cisco 2500 : hostname 2500 ! username 4500 password 0 foobar ip subnet-zero multilink virtual-template 1 ! interface Loopback0 ip address 20.20.20.1 255.255.255.0 ! interface Virtual-Template1 ip unnumbered Loopback0 no ip mroute-cache ppp authentication chap ppp multilink ! interface Serial0 no ip address encapsulation ppp no fair-queue pulse-time 3 ppp multilink ! interface Serial1 no ip address encapsulation ppp no fair-queue pulse-time 3 ppp multilink ! router rip network 20.0.0.0 Cisco 4500: hostname 4500 ! username 2500 password 0 foobar ip subnet-zero multilink virtual-template 1 ! interface Loopback0 ip address 20.20.30.1 255.255.255.0 ! interface Virtual-Template1 ip unnumbered Loopback0 ppp authentication chap ppp multilink ! interface Serial1 no ip address encapsulation ppp no fair-queue clockrate 2000000 pulse-time 3 ppp multilink ! interface Serial2 no ip address encapsulation ppp no fair-queue clockrate 2000000 pulse-time 3 ppp multilink ! router rip network 20.0.0.0 ! no ip classless ---------------------------------------------------------------------------- -------------------------------- problem : 4500#sh int virtual-template 1 Virtual-Template1 is down, line protocol is down -------------------------------> it should be up isn't it ?
