I would like to ask a couple of questions regarding IS-IS 
packet encapsulation.

1. Does anyone kwow routers or switches supporting an IS-IS over IPv4
    encapsulation  as well as a data link layer encapsulation ?

2. Does Cisco router support an IS-IS over IPv4 encapsulation? 
    If it support only data link layer encapsulation, 
    does it support IS-IS over Ethernet, IS-IS over AAL5 or IS-IS over POS?

3. I was told that GateD routing module supports the IS-IS over IPv4
    encapsulation. Is that right?

4. Is there any ongoing internet draft that defines the IS-IS over IPv4 encapsulation, 
    or just a prorietary encapsulation? 
    I was told that the IS-IS over IPv4 draft is currently outdated and not progressing.
    Does it mean that the corresponding standardization comes to an end ?

Any response will be greatly appreciated.

Regards,

Yongjun
