Multilayer Switching- SVIs

In this lab I created two switch virtual interfaces (SVIs) on int vlan 10 and vlan 192. I assigned fa0/1 with vlan access 10 and fa0/2 with clan access 192.

Switch#config t
Switch(config)#int vlan 10
Switch(config-if)#
%LINK-5-CHANGED: Interface Vlan10, changed state to up

Switch(config-if)#ip add 10.1.1.1 255.255.255.0
Switch(config-if)#exit
Switch(config)#int vlan 192
Switch(config-if)#ip add 192.168.1.1 255.255.255.0


Switch(config)#int fa 0/1
Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan 10


Switch(config-if)#int fa 0/2
Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan 192

Here I tested that the switch could see the hosts which were configured according to the diagram and with the SVI as the default gateway.


Switch#ping 10.1.1.2

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.1.1.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 3/5/7 ms

Switch#ping 192.168.1.2

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 4/4/4 ms

Next I tried to ping from host 10.1.1.2 to host 192.168.1.2 but it failed. The reason it did was because my default ip routing is disabled on multilayer switches.

Here I enabled ip routing and verified with show ip route that connected route when in the routing table.


Switch#config t

Switch#show ip route

Codes: C - connected, S - static, I - IGRP, 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

     10.0.0.0/24 is subnetted, 1 subnets

C       10.1.1.0 is directly connected, Vlan10

C    192.168.1.0/24 is directly connected, Vlan192

Now the ping is successful once routing was enabled.
