3580.0. "MPC-III and Level1 routing vector V3.1-9" by UTOPIE::BERG_W () Tue Mar 25 1997 10:44


Hello!

For test purposes i wanted to configure a DECnis600 Version V3.1-9 with an 
MPC-III card.
At Level 1 the routing protocol should be "Routing Vector" and at
    Level 2 "LINK State".

The NCL script told me, that i did right.
.
.
set routing manual L1 algorithm routing vector
set routing manual L2 algorithm link state
set routing Integrated ISIS protocols { ISO8473 }
.
.
After a reload the router told me 

    Manual L1 Algorithm               = Link State
    Manual L2 Algorithm               = Link State

So i tried do manually set the L1 Algorithm. This worked as long as i included a
ROUTEABOUT Access EW/MP on the same net.
This routeabout is also configured as L1( routing vector) and L2 (Linkstate) 
and has the same behaviour . Both, L1 and L2 are Linkstate after restart.

*
t 6
config>p osi
OSI_config>list algo
OSI config>list algo
Level 1 Algorithm = DISTANCE_VECTOR
Level 2 Algorithm = LINK_STATE

    ==Restart
    
t 5
+ p osi
OSI>dnav
DNAV Level 1 Routing Algorithm: LINK_STATE
DNAV Level 2 Routing Algorithm: LINK_STATE

At the RouteAbout i'm not able to manually set the right algorithm.
    
But the interresting fact is, that the Decnis had a "Software Crash" at the 
moment i restarted the Routeabout.

Is there something i forgot in my config ??
Could there be a bug using MPC-III cards and V3.1-9 (V4.0 is the next step i
will try) ??
Another DECNIS with MPC-I and V3.1-9 works correct with the same config.


Any help will be highly appreciated.

Thanks,

Wolfgang

The version  of  MPC  you  have  in  the  DECNIS does not affect the way the
routing  protocols  operate  (  apart  of course from being faster on an MPC
III).

This seems  to imply that you are loading a different script into the DECNIS
from the one where you set the algorithm to 'routing vector'.  Is the script
being  loaded  from  the network or flash ? If it is being loaded from flash
make sure the correct flash area has been chosen.

Changing routing  algorithms  on  the  fly  will not work and will result in
unexpected  behaviour.   The  fact  that  the  DECNIS  allows you change the
algorithm on the fly is a bug.

	>This routeabout is also configured as L1( routing vector) and L2 (Linkstate)

This does not make sense at all.  The presence/absence of other routers does
not  affect  the  configuration  of  the  DECNIS.  The DECNIS will configure
itself according to what is in the cmip script.

	>But the interresting fact is, that the Decnis had a "Software Crash" at the

Can you supply a crash dump so that we can analyse it ?

	>Another DECNIS with MPC-I and V3.1-9 works correct with the same config.

The most likely explanation is that the DECNIS is not loading the script you
think  it  should.   Going  to V4.0 will not make a difference and as I said
before  the  version  of  the  MPC  card does not affect the way the routing
protocols operate.

    Sorry,sorry,sorry........
    
    As you aspected, the router was loaded from another host.
    
    Thank you very much for your answer.
