Cisco 5500/RSM VLAN problem

[kcbell]

After I created the VLAN2 and activated the VLAN2 in the 5500, I cannot access the host on valn2 on the 5500. I was able to ping from the router to the switch and the host on VLAN2 but I cannot ping the host in VLAN2 from switch. The 5500 switch said VLAN2 is unreachable.

ip for vlan1 is 192.168.1.1 255.255.255.0
ip for router is 192.168.1.1
ip for switch is 192.168.1.2
ip for vlan2 is 192.168.2.1 255.255.255.0

a "sh vlan" shows that vlan2 is active.

I can ping the gateway of vlan2 from the host. I can also ping the router but I cannot ping the switch.

What am I missing?

Did you set the default gateway on the 5500 switch to 192.168.1.1? (I assume that your router is doing inter-vlan routing using sub-interfaces and encapsulation isl/dot1q, so your hosts should be using the corresponding IP addresses on the sub-interfaces as their default gateway)

Do a show ip route on the 5500 and it will show you what the default gateway is , should be the router interface for vlan 1 I assume . You would have to post the 5500 configs and maybe the router configs minus the addresses so we could take a look if you can't figure it out .

PLease see the following. Thanks

Gateway of last resort is not set

C 192.168.2.0/24 is directly connected, Vlan2
C 192.168.1.0/24 is directly connected, Vlan1
C 127.0.0.0/8 is directly connected, Vlan0

Ok you must have an RSM card in the 5500 . Go into the switch side and do a sh ip route and make sure it says 192.168.1.1 for the default gateway . Also do a show vlan and make sure the port that you think is in vlan 2 actually is .

vipergg:

You are 10 minutes before me. I was going to post my results. You are exactly right! I need to add

set ip route default 192.168.1.1

Before adding the default the sh ip route would look like this

destination gateway
192.168.1.1 192.168.1.2
default default

After I added the line above, the sh ip route becomes

destination gateway
default 192.168.1.1
192.168.1.1 192.168.1.2
default default

and everything is fine now.

Thank!
