You can. If both are terminating on same router at either ends, you can configure a ppp multilink bundle and add these 2 interfaces to the multilink bundle.

Re: ISDN or adsl line load balancing

This depends on what configuration you are going for. i.e, for PPPoE or PPPoA

The three configs are

For PPPoE configuration

vpdn-group 1

accept-dialin

protocol pppoe

virtual-template 1

interface Virtual-Template1

ip address 150.150.150.1 255.255.255.0

ip mtu 1492

interface ATM0

no ip address

no atm ilmi-keepalive

pvc 15/100

protocol pppoe

!

dsl operating-mode auto

YOu shud replace the ip address and the pvc values. Also in newer IOS versions, vpdn commands are not required.

For PPPoA configuration

interface ATM0

no ip address

no atm ilmi-keepalive

dsl operating-mode auto

dsl power-cutback 0

interface ATM0.1 point-to-point

ip address 192.168.10.11 255.255.255.0

pvc 16/100

encapsulation aal5mux ip

and

interface ATM0

no ip address

no atm ilmi-keepalive

dsl operating-mode auto

dsl power-cutback 0

interface ATM0.1 point-to-point

ip address 192.168.10.11 255.255.255.0

pvc 16/100

encapsulation aal5snap

change the ip address.....and pvc values......

On the PVC I got it but on the IP side pls advise. I have 2 IP addresses allocated by my ISP.Which interface should I assigned too and how about the NAT inorder to allow all my LAN Ws to acces the net.
