All,
I have been experimenting with Dialer Watch as a backup medium to frame
relay and using ospf as the routing protocol.
CCO says this should work
www.cisco.com/warp/public/access_dial/bri_isdn_11048.html
However when using this config ospf packets multicasted to the 224.0.0.5
address keep the isdn link active, I have tried every combination to get
this working, i.e :-
No peer neighbor routes
ISDN Point to Point network types
etc etc
obv an access list solves this, but then ospf dies.
And I have come to the conclusion that to use dialer watch as a backup
medium in conjunction with ospf you need to have demand circuit enabled as
well as dialer watch, as demand circuit kills the hellos etc ect and dialer
watch looks after the watched routes.
Has anyone else come across this scenario ?
Thanks
Steve
