Whether the Vlan10 and Vlan20 in the Center Router are two virtual router interfaces?












4















I have a ISP 4321 Router in my Cisco Packet Tracer. and I added a NIM-ES2-4 module in the Router, that provides four switching ports. and now, I configured two VLANs to the two switch port of them. and now it created the two VLANs, you can see below, there are Vlan10 and Vlan11:



Router#show ip interface brief 
Interface IP-Address OK? Method Status Protocol
GigabitEthernet0/0/0 unassigned YES unset administratively down down
GigabitEthernet0/0/1 unassigned YES unset administratively down down
GigabitEthernet0/1/0 unassigned YES unset up up
GigabitEthernet0/1/1 unassigned YES unset up up
GigabitEthernet0/1/2 unassigned YES unset up down
GigabitEthernet0/1/3 unassigned YES unset up down
Vlan1 unassigned YES unset administratively down down
Vlan10 10.10.10.1 YES manual up up
Vlan11 10.10.20.1 YES manual up up


I want to know whether the Vlan10 and Vlan11 are two virtual Router ports?





If the Vlan10 and VLan11 are two virtual Router ports. I have configured the IP address on them, you can check the upper data. and I assigned the Vlan10 to GigabitEthernet0/1/0, the Vlan11 to GigabitEthernet0/1/1, all are access mode.



enter image description here



but now I cannot from 10.10.10.2 to ping 10.10.20.1:



Router>ping 10.10.20.1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.10.20.1, timeout is 2 seconds:
.....
Success rate is 0 percent (0/5)


the Center Router(Router11)'s route is bellow:



Router#show ip route
Codes: L - local, 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, E - EGP
i - IS-IS, 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

10.0.0.0/8 is variably subnetted, 4 subnets, 2 masks
C 10.10.10.0/24 is directly connected, Vlan10
L 10.10.10.1/32 is directly connected, Vlan10
C 10.10.20.0/24 is directly connected, Vlan11
L 10.10.20.1/32 is directly connected, Vlan11




So my questions are:




  1. Whether the Vlan10 and Vlan20 in the Center Router are two virtual router interfaces?

  2. Why the Router 10 can not ping the Router11?

          1. Yes, these also called switch virtual interfaces or SVI.

          2. Because your Router10 don't know how to get to 10.10.20.0/24 network.
            Add route to Router10 configuration:


          #(conf-t) ip route 10.10.20.0 255.255.255.0 10.10.10.1

          @three-blocks, same thing here. Your Router4 (I'm assuming that he's got 10.10.20.2 IP) don't know anything about 10.10.10.0/24 network. So same solution: on Router4 #(conf-t) ip route 10.10.10.0 255.255.255.0 10.10.20.1
