Hello all,
I was trying to setup the ISDN floating static route to backup the
frame relay circuit, but have ran into some problems.
On all the spoke sites, I have only default route pointing to the hub
site and another default route with higher administrative distance
pointing to hub site¡¦s ISDN as backup.
On hub site, I have ODR enabled to learn all the networks from all the
spoke sites via frame relay circuit and have configured ISDN dialer
profile with floating static route to back up each spoke sites.
If spoke site¡¦s frame relay down, the ISDN will kick in no problem, but
if hub site's frame relay down, even the hub site's ISDN kick in but
since spoke site¡¦s frame relay was up and the floating static route
won¡¦t take over, the packets will still been sent to the frame relay
interface.
What should be the solution for this problem?
May be on the lab exam it won¡¦t be any static route need to be
configured, just some questions that I ran into when I tried the dialer
profile, ODR¡K
Here are the partial config for both hub and spoke routers:
