Hi,
I have a problem that I don´t undertand that is happening in my network.
I have one architecture like the bottom picture. PC1 and PC2 have internet. However when I do one ping from PC1 to PC2 I have no answer. If I do one ping from L3 switch to PC2 I has ping.
Which could be the problem?
Regards.
These are the route and AC list.

Hello,
I did not find the picture. The configuration from devices is also too difficult to read. Put as txt attached or insert as code by using the simble </> above.
Also, send me the route table from both PC.
-If I helped you somehow, please, rate it as useful.-

Hi,
I can see the picture and I have the text between </>. I don´t know what is the problem in the topic.

Hi there,
Is PC1 using the linksys router as its default gateway (10.0.0.254) ? If so, does that router have a route to VLAN1 ? Something like:
! ip route 192.168.0.0 255.255.0.0 10.0.0.1 !
cheers,
Seb.

PC1 has 10.0.0.1 gateway and PC2 has 192.168.1.1
Thanks for the help.

I have these sentence in the Switch L3
ip route 0.0.0.0 0.0.0.0 10.0.0.254
10-06-2017 05:38 AM
What is the output for:
sh ip arp vlan 1
sh ip arp vlan 2
sh mac add | inc 1/0/5
sh mac add | inc 1/0/10
cheers,
Seb.

The output is the next ( I have summaried it)
Switch#sh mac add | include 1/0/5 2 547c.6946.ef30 DYNAMIC Gi1/0/5 Switch#sh mac add | include 1/0/10 2 fcaa.14ce.8a9e DYNAMIC Gi1/0/8 Switch#sh ip arp vlan 2 Protocol Address Age (min) Hardware Addr Type Interface Internet 10.0.0.1 - 58ac.7899.99f7 ARPA Vlan2 Internet 10.0.0.254 0 c056.2773.3167 ARPA Vlan2 Internet 10.0.0.71 137 fcaa.14ce.8a9e ARPA Vlan2 NaveNueva#sh ip arp vlan 1 Internet 192.168.11.100 0 0024.9b23.04dd ARPA Vlan1
It seems all right, doesn't it?

Anybody think something about this issue, please?

This output looks to have been edited too much! :)
sh mac add | include 1/0/10
Shows a mac address on 1/0/8
Also I assume the output was all gathered on the same L3 switch (3560), but the hostname changes from Switch to NaveNueva .
Can you provide the following output (un-summarised):
sh mac add dyn vlan 1
sh mac add dyn vlan 2
sh ip arp vlan 1
sh ip arp vlan 2
Also what are the MAC addresses of PC1 and PC2?
cheers,
Seb.

Hi,
sh mac add | include 1/0/10
Yes, I have edited fastly becouse I had changed the PC's port and I want to keep the picture scenario.
Now it is the port 8.
NaveNueva#sh mac add | include 1/0/8 2 fcaa.14ce.8a9e DYNAMIC Gi1/0/8
Also I assume the output was all gathered on the same L3 switch (3560), but the hostname changes from Switch to NaveNueva
Yes, I forget edit the name of NaveNueva to Switch sorry.
sh mac add dyn vlan 1 . . . 1 0024.9b23.04dd DYNAMIC Gi1/0/17 . . .
