I have two routers (RTRA & RTRB) setup on a frame relay network. RTRA acts as the primary while RTRB acts as the secondary. Both routers are using NAT. If connection to RTRA fails traffic would failover to the secondary, causing the NAT Table to populate.
My question is how long would the system store the NAT Table on RTRB if traffic was restored on the primary? Will RTRB maintain the NAT Table until the router was reloaded?
