I have 2 routers in a remote site. They are configured as a primary and a
backup using HSRP.
The primary has several serial attached SDLC devices that connect to a host
at the central site using SDLLC. The primary conncts to the central site
using a T-1 link. The primary and backup routers both reside on the same
Ethernet segment.
When the T-1 link fails, the workstations on the Ethernet segment can
connect to the central site using the backup router, which has an ISDN
interface that becomes active whenever the primary's T-1 fails. HSRP takes
care of this - no problem...
My questions are: How will the serially attached SDLC devices respond when
the T-1 link fails? Will they be able to take advantage of the ISDN link on
the backup router? What will happen to existing SNA sessions when the link
fails?
Any help on this would be appreciated. Unfortunately, I do not have a lab
where I can adequately test this scenario...
Thanks!
Dale
