What command do I use to be sure my BRI and PRI backups for frame relay drop when the frame comes back up?

[admin_2]

I want to be sure the ISDN drops when the frame comes up, not just when it sees no traffic across the ISDN interface. 6 sites with 1750s/BRI/Frame FT1 and a 3640/PRI/Frame T1. I'm using OSPF, static floating routes and dialer maps to trigger the ISDN connetions.

With static floating route as your

backup mechanism, I'm afraid you'll

have to reply on idle-timeout to bring down the link.

You might want to set a value lower that the 120sec as default

but its not really recommended as slow application might cause the link to

timeout while in backup mode.
