Hi,




You cannot ping R1 because there's no route back. On R1, configure a static route or dynamic routing protocol b/w R1 and R2

The easiest thing would be to add a static route on R1 to the 10.0.0.0 major network


ip route 10.0.0.0 0.255.255.255 [R2 serial interface ip address]


I also see that you have set up R1 and R2's serial interface ip address to 192.168.1.3. Please correct that as well. And according the diagram the default gateway on labSw2-2912-xl must be 10.0.0.3 [R1's e0/0 ip address]

Try


ip route 10.0.0.0 255.0.0.0 192.168.1.x where x is whatever the next-hop is.

":why it did not take 10.0.0.0 0.0.0.255 192.168.1.x "


because when you define static route you define destination address with subnet mask whereas 0.0.0.255 is wildcard mask


From the PC ur r pinging set deafault gateway as 10.0.0.3 the router R2 ip address.


U have to set Ip address for R1 also and define static route on R1 also. Host at R1 will have deafult gateway as Ip of R1.

so the default gtwy for the switch should the the next the interface of the next hope. because on R2= I have the ip is 10.0.0.3 and the gtwy is 10.0.0.1 is that not correct ..


Thanks Bud

yes u r right for switch the deafult gateway is IP of next hop so that it can pass that info to the router if it is not for the switch.

Even for the host connected to that switch default gateway is the IP of the router.


Is ur setup working now?

First start with routing

static routing, routing protocols


then switching

switching, bridging, vlans, spanning-tree, trunking etc


and finally security.
