Multilink PPP between HSSI and HWIC-2T

Dear all,

µWe have 2 routers. One of the router has 2 HSSI interfaces and the other has 2  HWIC-2T.
Each HSSI is connected to one port of each HWIC-2T  interface.

We used to configure MLPP between same models WIC.

Using the same best practice configuration, we are not able to bring interfaces to UP status.

I'd like to know if it is possible to configure multilink  between Those cards (HSSI and HWIC-2T).

Regards.

Hello Tranarison,

HSSI is a totally different standard using ECL and negative voltages you cannot connect it to a synchronous serial.

>> One of the router has 2 HSSI interfaces and the other has 2  HWIC-2T.
Each HSSI is connected to one port of each HWIC-2T  interface.

the problem is not multilink PPP but different physical layer standards
