    Inter vlan routing


      Hello friends, I have Router_A (FastEthernet0) and Router_B (FastEthernet0) connected to Switch_A on FastEthernet1/0/1 and FastEthernet1/0/2.


      FastEthernet0 IP address: /24



      FastEthernet0 IP address: /24



      Vlan123 IP address: /24


      Both FastEthernet1/0/1 and FastEthernet1/0/2 belong to VLAN123 on the switch.


      Port      Name               Status       Vlan       Duplex  Speed Type

      Fa1/0/1                      connected    123        a-full  a-100 10/100BaseTX

      Fa1/0/2                      connected    123        a-full  a-100 10/100BaseTX


      I have EIGRP running on both routers and neighbors are UP on both ends.


      I have another VLAN on the switch (VLAN120) with IP address /24.

      I have port FastEthernet1/0/13 assigned to VLAN 120 and it has a PC plugged into it with IP address /24


      IP Routing is enabled on the switch.

      From the switch I can ping both routers.

      From the PC I am able to ping but I can't ping or .3.


      What do I need to configure on the switch in order for my PC on vlan 120 to be able to ping the routers?
