IS-IS and OSPF

["Johnson Kuruvila" <kuruvila () nortelnetworks com>]

Hi All,

I hope this mail is appropriate for the charter of Nanog.
Pardon me if it is not.

Could someone comment on:

Normally, is there is a need to run both IS-IS and OSPF
on the same interface on a router? How does the vendors
today support this?

Thanks a million,
