Hi,

The config is exactly the same as on serial interface. You dont have to do anything special.

interface Multilink1

ip address 192.168.19.6 255.255.255.0

no cdp enable

ppp multilink

multilink-group 1

!

interface Serial1

no ip address

no ip directed-broadcast

encapsulation ppp

no fair-queue

ppp multilink

multilink-group 1

!

interface Serial2

no ip address

no ip directed-broadcast

encapsulation ppp

no fair-queue

ppp multilink

multilink-group 1

Hi thank you Amit

And I want to configure Isdn as backup ,so in which int should I apply the backup int .Is it under Int multilink 1? .If I am using static routes what should

be the routes .

To use ISDN as back, give the back up interface command unset multilink interface. As far as our multilink interface is up we are going via serial and the moment it goes down the ISDN should fire up.

The static routes that you will use would be something

ip route 0.0.0.0 0.0.0.0 next hop multilink ip

or

ip route 0.0.0.0 0.0.0.0 multilink 1

and for ISDN

ip route 0.0.0.0 0.0.0.0 bri0 <+++ ISDN interface

Hi Sudeesh,

One point I missed out in our static route defination, just use the default route for ISDN as the floatic static route. I.e define it in this way

ip route 0.0.0.0 0.0.0.0 bri0 100 <++ this is administrative distance whihc will make this route as floating static route,

Also for carrying out your voice traffic completely on a diff interface you can use PBR i,e policy routing. This will route the traffic matched on the intersting traffic and will take the exit interface as defined by you.
