(ASCEND) Ascend Pipelines/MAX 4048's and ciscos

[Chris Rogers <phiber@phiber.org>]

-----BEGIN PGP SIGNED MESSAGE-----

I am presently having a problem with my cisco routers and Ascend
Pipelines/4048's.  Heres the situation:

We have a 208.236.212.0/24 subnet here.  We have a remote site with a
208.236.213.0/24 lan network and also 208.242.224.0/24 and
208.242.225.0/24 for dialups.  We have a transit subnet of
208.236.215/0/24 that we use for our OSPF routing.  Here we are using a
Cisco 3620 to route to the remote site via a T1 Framerelay.  The
framerelay is on subinterface serial 1/1.1 with DLCI 110.  The remote end
has a Pipeline coming back here with DLCI 120.  If I put static routes
into the cisco to point to all the remote end networks, everything goes
well.  However, when I attempt to route via OSPF, thats when things break. 
The pipeline on the remote end sends hello packets and LSA's to the cisco
here, but it doesnt advertise any of the networks in its area.  Hence, I
cant route in, and my dialup customers cant route out.  If I ping the wan
port of the Pipeline when I'm running OSPF, 50% of all my packets are
dropped, and its exactly 50%.  I can not ping its ethernet side,  nor
anything inside of it.  'sho ip os nei' sees the pipeline on the other
end, but nothing beyond it.  'sho ip route' shows nothing behind the
pipeline as well.  When I static route to the remote end, the pipeline
sees the cisco as a neighbor, but thats all it does.  It shows no error
packets.

Here are parts of the configs that are on the cisco here at the local
side:

!
interface Serial1/1
 ip address 208.236.215.1 255.255.255.224
 encapsulation frame-relay IETF
 ip ospf authentication-key <authkey>
 bandwidth 1544
 frame-relay lmi-type ansi
!         
interface Serial1/1.1 point-to-point
 ip address 208.236.215.1 255.255.255.224
 ip ospf authentication-key <authkey>
 bandwidth 1544

 network 208.236.213.0 0.0.0.255 area 0.0.0.0
 network 208.236.215.0 0.0.0.255 area 0.0.0.0
 network 208.242.224.0 0.0.0.255 area 0.0.0.0
 network 208.242.225.0 0.0.0.255 area 0.0.0.0
 area 0.0.0.0 authentication
 area 69.0.0.0 authentication
 area 69.0.0.0 range 208.236.212.0 255.255.255.240
!


Right now we are putting the networks into area 0.0.0.0 until I can figure
out what the problem is, and then I will be putting them back into their
appropriate areas.

pipeline 220 running 6.0.10 ta.p22
cisco 3620, dual ethernet, 4 t1 CSU/DSU mods, 11.3(3a)T

Any help would be greatly appreciated.  Thanks.
