I have 2 systems, one at 192.168.10.5 runs a dhcp server, one at 192.168.10.66 runs the CML ova and the UI. I create a topology under CML which consists of a ext-conn device, an un-managed switch, and iosv device and an iosvl2 device. All devices are connected to the un-managed switch. I configure the iosv device to get it's address via dhcp. I also configured the iosvl2 device to get it's address via dhcp. When I start the simulation the iosv device get's its address from dhcp and all is fine. The iosvl2 device nothing. Now to configure the iosvl2 switch I did as follows:
conf t
vlan 10
name 192Subnet10VLAN
int vlan 10
ip addr dhcp
ip dhcp client request dns-nameserver
ip dhcp client request domain-name
ip dhcp client request router
shut
no shut
end
I also did the following:
truckin-iosvl2(config)#vrf definition Mgmt-intf
truckin-iosvl2(config-vrf)#address-family ipv4
truckin-iosvl2(config-vrf-af)#int vlan 10
truckin-iosvl2(config-if)#ip address dhcp
truckin-iosvl2(config-if)#
truckin-iosvl2(config-if)#ip dhcp client request dns-nameserver
truckin-iosvl2(config-if)#ip dhcp client request domain-name
truckin-iosvl2(config-if)#ip dhcp client request router
truckin-iosvl2(config-if)#shut
truckin-iosvl2(config-if)#no shut
truckin-iosvl2(config-if)#exit
truckin-iosvl2(config)#ip route vrf Mgmt-intf 0.0.0.0 0.0.0.0 192.168.10.65
truckin-iosvl2(config)#end
when I do sh run to look at the config I see:
interface Vlan10
ip address dhcp
!
None of the other dhcp commands are shown. Also as soon as I created vlan 10 I get a console message:
*Jun 10 21:29:54.826: %LINK-3-UPDOWN: Interface Vlan10, changed state to down
No matter how many times I try to do a no shut on vlan 10 it never changes state from down.
truckin-iosvl2#sh ip int br
Interface IP-Address OK? Method Status Protocol
GigabitEthernet0/0 unassigned YES unset up up
GigabitEthernet0/1 unassigned YES unset up up
GigabitEthernet0/2 unassigned YES unset up up
GigabitEthernet0/3 unassigned YES unset up up
Vlan10 unassigned YES manual down down
It doesn't even show vlan 10 as having method dhcp.
The main thing that is driving me nuts is why can't I ping devices outside the topology? The iosv device gets its address from a system outside the topology why can't I then ping that device? I have attached the iosvl2 config
truckin-iosvl2#sh 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

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, H - NHRP, l - LISP
a - application route
+ - replicated route, % - next hop override, p - overrides from PfR
Gateway of last resort is not set
Any help is appreciated.
I tried to add the configuration by click on "Choose Files" and chose the configuration file, but I got an error saying "The contents of the attachment doesn't match its file type." So here is the config:
