I have a problem with Frame Relay in GNS3 which i need your ideas, I setup 4 routers one of them is a Frame Relay switch, everything is good and i can ping perfectly, but there is 2 problems:
1. I can't ping the serial interface of the local router, S0/0 IP add 10.1.1.1 I can't ping it from the same router where i configured this ip address.
2. Sometimes Line protocol is UP sometimes, it is DOWN, You know that there is a Keepalive of 10 seconds, do you think there is a timeout over 10 seconds that cause the not hearing of frame relay from the routers? Specially that GNS3 consumed 60% of my CPU, I'm running it in a Acer Celeron 1.73 Ghz and 1.5 Go RAM, do you think it is the delay? because sometimes the Line protocol in the interface of each router is UP for a while then suddenly it is Down, so i assume that there is a delay of or the Frame Relay Switch doesn't hear from the routers for over than 10 seconds? ( the keepalive timer)?
I Also want to know how to save the config because I lost it now when i saved the topology.
