(ASCEND) Ascend GRF 400 routing



Hi,

I've recently obtained a new GRF 400 switch for Ascend that I'm trying to
setup routing for.  Here are the particulars of my network:

Remote serial WAN interface:  157.130.176.117/30
Local serial WAN interface:  157.130.176.118/30

GRF IP address:  208.218.220.254/24
Default gateway:  157.130.176.117

Routing downstream for:

208.218.220.0/24
208.218.221.0/24
208.218.222.0/24
208.218.223.0/24

--------------------------------------
In the grifconfig.conf file, I've put:

<name>  <address>         <netmask>
de0     208.218.220.254   255.255.255.0
gs020   157.130.176.118   255.255.255.252

The first is for the maintenace ethernet interface and reflects the IP
address of the GRF itself.  The second is the interface for the HSSI card
in Slot 2, Port 0, and reflects my local serial WAN interface.  The HSSI
port is connected to a Larscom CSU/DSU.  I've configured my
hssi-frame-protocol = Frame-Relay

-----------------------------------
In the grroute.conf file, I've put:

<dest>    <netmask>   <gateway/next hop>
default   0.0.0.0     157.130.176.117

--------------------------------
In the grfr.conf file, I've put:

    <slot> <port> <optional parameters>
link 2      0     name="Upper Port 2"  LMIType= AnnexD   AutoAddGrif = gs020

     <lif>  <dlci> <peer ip address>  <optional parameters>
pvc  gs020   500   157.130.176.117    Name="UUNET"  Enabled=Y

---------------------------------
In the grppp.conf file, I've put:

interface gs020
  enable ipcp

---------------------------------

With this setup, I'm able to ping 208.218.220.254 (the GRF's IP) and
157.130.176.118 (the HSSI port IP), but not 157.130.176.117 (my remote
serial WAN interface and default gateway).

Any help or pointers would certainly be appreciated.

Thanks,
Chuck Powers
