I have a setup of two L3 switches and one router. Am I missing something very fundamental here, or this is a GNS3 error?
Thanks in advance for any help!
I can ping from 10.99.99.3 to 10.99.99.1 and visa versa. However, I cannot ping from 10.99.99.3 to 10.99.99.2, or visa versa.
Here is the pertinent config:
10.99.99.1
!
interface Vlan99
ip address 10.99.99.1 255.255.255.0
!
interface FastEthernet1/3

speed 100
!
10.99.99.2
!
interface Vlan99
