I have confiured Leased line as primary with ISDN as back up. When leased line goes down , we are able to ping ISDN IP from router . But from PC we are not able to ping LAN of remote side.
When we do show ip router in router , it still shows next hop as leased line .
Both ends static router have been configured with ISDN AD as 50 & for leased line AD as 1.
My concern is that why next hop is pointing towards Leased line when ISDN is UP.
