TOPIC: 3560 Layer 3 Question

3560 Layer 3 Question 10 years 3 weeks ago #26643

I have a 3560 Cisco Switch in layer 3 configuration port 1: 10.0.0.248/24 port 5:10.3.4.248/24 port 9:10.10.1.248/24. Port 1 is connectec to another 2950 Cisco switch which is also connected to inside interface (10.0.0.2) of a Pixz515e firewall. hosts connected on Port 5 and 9 can ping each other but cannot ping any host connected on 2950 switch. The default route of 3560 is set to 0.0.0.0 0.0.0.0 10.0.0.2. What is need to be done on 3560 so that it can ping the host connected on 2950. From 3560 i can ping any host connected on 2950 switch and also the inside interface of the firewall but why I can't ping from any host connected on port 5 and 9. Any suggestion is appreciated.

Sounds like the hosts on the 2950 do not have a route back to 10.3.4.0/24 and 10.10.1.0/24.
