I do a lot of work with switched, private networks (for industrial control), but very little with routers. I'm trying to pass the CCNA but failed the routing parts. So, my friend gave me an old 3600 router, and I'm using a SGE-300 switch running CLI and then a stack of SG-2000P small business switches to learn this stuff.
I have them configured like this:
SGE2000P switch stack with a number of hosts on VLAN1, which has an IP address of 192.168.111.1/24
Connected to:
Ethernet0/0 of the 3600 router, with an IP address of 192.168.111.201 /24
Ethernet0/1 of the 3600 router, with an IP address of 10.0.0.1/8
Connected to:
SGE300 switch with a host on VLAN1, which has an IP address of 10.0.0.11/8
From the router, I can ping a host on the 192.168.111.0 network:
JohnHRouter#ping 192.168.111.21
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.111.21, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms
and, a host on the 10.0.0.0 network:
JohnHRouter#ping 10.0.0.111
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.0.0.111, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms
But, I can't ping from the 192.168.111.21 host to the 10.0.0.111 host, or vice versa.
I can see the networks in the routing table:
JohnHRouter#show ip route
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route
Gateway of last resort is not set
C 192.168.111.0/24 is directly connected, Ethernet0/0
C 10.0.0.0/8 is directly connected, Ethernet0/1
I added a command for "IP Routing", and here's my running-config file:
JohnHRouter#show run

I tried adding a "router RIP" command but that didn't work either.
I'm sure this is some stupid thing I'm missing. Any suggestions?
Thanks!
John
