Don't forget on P-P links, Cisco's HDLC isn't supported by some vendors.
PPP is more standardized.

Pat,
It very much depends on what you want to implement, however in all cases
stay with the industrial standards and run away from all proprietary
implementations either from Cisco side or from the vendor's side.
For a frame relay implementation, make sure your encapsulation on both
ends
are the same, offcourse you will not use CISCO because your vendor might
not
support it.
LMI type are now auto-discoverable, but you might want to hard code.
I think the standard is still the same on cisco side to defined these
parameters appropriately in either the interface or pvc level as you
would
if it were a cisco-to-cisco implementation, the major difference comes
in
the value of each of the parameters. It is also better to start from the
vendor router and see the parameters they support and match those
parameters
on Cisco's side.
On switching, they are alot, but offcourse you will not want to use ISL
trunk encapsulation.
Timers are also a big area to watch in some implementations, the vendor
might be using timers different from Cisco's and you might have some
glitches with technologies that require these timers to be compatible or
the
same at both ends.
In routing, you would not want to implement eigrp or ripv2. Even in your
implementations of ospf, bgp, etc they are some cisco flavors or
additions
that you would not want to go into.
Like I said, it really much depend on what you want to implement, there
are
other areas of differences eg in multicasting, QoS, ISDN, ATM, etc.
In this field, there are three ways of doing things, the Cisco way, the
Vendors way, the industrial standard way and since all Vendors including
Cisco incorporates the standards (if a standard had been defined), you
are
better off staying in the middle.
Good luck!
