We have recently had to 'back peddle' on some of our pm's from ospf TO
ripv1 due to a compatibility issue with USR's lack of OSPF capability
(doh!). What suprises me, is, that with only RIPv1 on the pm's, how do
they manage to broadcast the /28 mask (16 ip addresses) back and forth
between the other Pm's, but our Cisco, listed below sees only the /32 (the
single ip address) of hte connection.
To put it another way, the Livingston pm's seem to be 'sharing' the subnet
mask's via RIPv1 (which it shouldn't know how to do) yet the same RIP
broadcasts on the same ether interface does not include the subnet masks
to the cisco router. It seems like Livingston is running RIPv1Enhanced
and only the livingston's speak it :) Damn USR for not putting OSPF in
there- else I would have to deal with rip again. At least USR has Rip V2,
but the RIPv1Enhanced don't like Rip V2 either :(
Time to re-read the RFC's I guess for me. I miss ospf :)
