Hello all,
I've started to do ip3xpert labs, and it's one of the first ones.
but I got stuck in one problem, which I don't know if is dynamips bug, or my
config,
most probably it's my config :)
the routers are 3640 model, switches are the 3640 routers too but with
switch module NM-16ESW.
diagram is following -> R5 f0/0 <----> f1/5 SW1 f0/1 <----> f0/1 SW2
f1/6<----> f0/0 R6
link between SW1 and SW2 is trunk.
following config:
SW1#sh run int f0/1
Building configuration...
Current configuration : 56 bytes
!
interface FastEthernet0/1
switchport mode trunk
SW2#sh run int f0/1
Building configuration...
Current configuration : 56 bytes
!
interface FastEthernet0/1
switchport mode trunk
------------
I have created VLAN 567 on SW1, and i can see that vlan replicates ok to
SW2.
on SW1 port f1/5 is in VLAN 567, and in SW2 port f1/6 is in VLAN 567 too.
here's config:
SW1#sh run int f1/5
Building configuration...
Current configuration : 61 bytes
!
interface FastEthernet1/5
switchport access vlan 567
end
SW2#sh run int f1/6
Building configuration...
Current configuration : 61 bytes
!
interface FastEthernet1/6
switchport access vlan 567
end
the link's are all UP UP.
on R1 int f0/0 has ip: 150.50.7.5 255.255.255.128
on R2 int f0/0 has ip: 150.50.7.6 255.255.255.128
but I can't ping one from another.
I tried following tests.
1) on SW1 I created interface VLAN 567, and put ip: 150.50.7.13
255.255.255.128
SW1#sh run int vlan 567
Building configuration...
Current configuration : 84 bytes
!
interface Vlan567
ip address 150.50.7.13 255.255.255.128
no ip route-cache
end
and from R1 I still can't ping this ip, output with debug on:
R5#debug ip packet
IP packet debugging is on
R5#ping 150.50.7.13 rep 1
Type escape sequence to abort.
Sending 1, 100-byte ICMP Echos to 150.50.7.13, timeout is 2 seconds:
*Mar 1 03:00:43.279: IP: tableid=0, s=150.50.7.5 (local),
d=150.50.7.13(FastEthernet0/0), routed via RIB
*Mar 1 03:00:43.279: IP: s=150.50.7.5 (local),
d=150.50.7.13(FastEthernet0/0), len 100, sending
*Mar 1 03:00:43.279: IP: s=150.50.7.5 (local),
d=150.50.7.13(FastEthernet0/0), len 100, encapsulation failed.
Success rate is 0 percent (0/1)
R5#
I have encapsulation failed, it can't resolve IP to MAC address.
2) if on SW1 I remove switchport on f1/5 and make it ip interface everything
works fine when I put ip 150.50.7.13 255.255.255.128.
I can ping this ip from R5.
If anyone has any idea, please let me know, I'm really frustrated...
Thank you very much.
