(ASCEND) OSPF on Cisco 2501 and Maxes

Hello all,

I've decided to move up to OSPF since I got tired of static routes.  I'm
new to OSPF and would like some advices from you experts.  Here are our
settings:

             Cisco 2501
                 |
       _______________________________
       |         |         |         |
   Max 4004  Max 4004  Max 4004  Max 6000
       |         |         |         |
      PRIs       PRIs      PRIs      PRIs

All of these are connected to the same switched 10/100 hub and has same
Class C addresses.

Cisco 2501:    aaa.aaa.aaa.1
MAXs:          aaa.aaa.aaa.2 - aaa.aaa.aaa.5

I'm not using global pool, but each Maxes has its own IP pool.

Some LAN users are using a subnet such as:
    bbb.bbb.bbb.32/29
    ccc.ccc.ccc.128/28

I usually make a route statement in Cisco 2501 like this
    ip route bbb.bbb.bbb.32 255.255.255.248 aaa.aaa.aaa.2      <- 1st Max
    ip route ccc.ccc.ccc.128 255.255.255.224 aaa.aaa.aaa.3     <- 2nd Max

If a LAN user (who usually dials to 1st Max) dials to 2nd Max, I have to
change the route statement on the Cisco router.  Will OSPF solve this?  And
if so, which software release should I use for 4004s (I'm using tbak.m40
right now)  Max 6000 already has OSPF feature in its software.

So far, I've entered these statements to the Cisco router:
     router ospf 1
     network 0.0.0.0 255.255.255.255 area 0

Do I need additional statements here?

For the Max 6000:
  OSPF options...
    RunOSPF=Yes
    Area=0.0.0.0
    AreaType=Normal
    HelloInterval=10
    DeadInterval=40
    Priority=5
    AuthType=Simple
    AuthKey=ascend0
    Cost=1
    ASE-type=N/A
    ASE-tag=N/A
    TransitDelay=1
    RetransmitInterval=5

  OSPF global options...
    Enable ASBR=Yes

Is this correct?

Thanks in advance.
