I have a 3750 (layer 2) switch hanging off core swich 4. A trunk connection is running between the two.
In order to access core swi4 we use SSH from my workstation .
My question is i cannot telnet or ssh to 3750 which has an ip of 192.168.21.11 (vlan 21) from my workstation.
The only way i can access 3750 is by ssh to core 4 and then telneting it to 192.168.21.11 (3750)
ospf network 192.168.21.0 0.0.0.255 is on core 4
transport input ssh telnet is configured on vty lines of 3750
As general practice if closet has an SVI for my PC's vlan and the connected core switch also an SVi for same vlan what do i use as my default gateway?? closet SVI or Core SVI
With the traceroutes you need to go onto the device where it stopped and work out why it cannot go any further. If in the case of the 3750 the traceroute only produced stars from the start then you need to logon onto the 3750 and work out why it has not route to your host. Is this 3750 acting as a L2 switch ?. If so check it's default-gateway, if it has one because it sounds like it might not.
As for which SVI to use i covered this in the other thread. If the closet switch is L2 then use the core SVI as default-gateway.
