[comp.dcom.sys.cisco] trouble with decnet atg

atmbnl@vax.oxford.ac.uk (06/28/91)

Hi all

I have a cisco IGS routing between two ethernets. Most of what I want it to do
works fine (ie IP etc), but I wanted to use the Decnet ATG as well. I seem to
have done something wrong. Any help anyone could provide would be much
appreciated.

A cut down description of our configuration looks like this


           +-------+                                              +------+
Rest       |Router1|                                            E0|Cisco |
of the --- |L2 Area|-Ethernet Lan with lots of Nodes in area 56,- |IGS   |
World      |56.X   | including a couple of L1 Routers             |      |
           +-------+                                              +------+
                                                                     |E1
								Ethernet with
								nodes in area
								49.

I currently have the set up with the cisco as a level-one router in both E0 and
E1, the cisco having appropriate addresses in area 56 and 49 respectively.
I have map table entries like
	decnet 0 map 56.60 1 49.140
	decnet 1 map 49.40 0 56.269
and expected to be able to communicate between 56.60 (on E0) and 49.40 (on E1).
But it doesn't work ...

(yes I have extended maximum_addresses for E0 to 1023).

The cisco is *not* the designated router on either network (when it was we
tended to see some end-node members of a vax cluster loosing their ability to
speak decnet to each other, and the configuration still didn't work).

Do I need to map the designated routers as well? (I can't see why I should have
to, but ...)
