Can't ping routers in my home network.

[bebop1065]

Hi all,

I've posted this in comp.dcom.sys.cisco also.

I have a 3550 switch SMI with three Vlans configured that I can ping, telnet and configure from my home network. The switch can ping and access the home network and the 'net.

I have a 3620 router that is connected to each of two vlans. The Routers can ping the switch but not the home network nor the 'net. I'd like to be able to telnet directly to the router from my home network without having to either console to it or telnet from the Switch. I can telnet and ping between the switch and router. I have a static route setup on the router to the switch as well as RIP to the network they share.

Can anyone take a look at my configs below to see what I might need to add in order for me to reach the routers directly?

Do I need to enable a RIP or static routing protocol on the switch as well? (I thought about this as I was making this post.)

Tell me I figured it out on my own!

Thanks.

Have you got anywhere with this yet?

Can you post some sort of network diagram?

You need RIP on the router.

Also, to route between VLANS (Why anyway have VLANS, unless this is a teaching env). You need IP Plus, you config is not showing as IP Plus (No trunk commans)

No, I haven't gotten anywhere with this. Thanks for responding.

I am able to telnet to my switch so, I can test this real world without having to go home. (That was a victory in itself.)

I enabled RIP on the switch with all networks declared. The routing tables on all elements show all available routes. I even see a route (192.168.0.0) to the Dlink router from the Cisco routers. But there is no ping reponse when I ping the Dlink. For learning purposes, I have also added static routes between the elements. The top config is RouterB. The bottom config is the 3550.

I haven't studied trunking yet, so that might be my answer.

If you wish to route between VLANS's trunking and IP Plus for routers are your friends.

I don't understand what this IP PLUS is. Is this something that I need to learn to pass the cert. test? Otherwise, I'd be ust happy enough tring to work with what I have.

One of my routers has 12.2(7c). The other has 12.1(5).

I should enable trunking between all of the VLANS and my home network?

yes, you have to enable trunking between all of the VLANS and your home network(Dlink). IP PLUS is just a feature set that will allow you to configure the ISL trunking. FYI: ISL- Inter-Switch Link= Cisco-proprietary protocol that maintains VLAN information as traffic flows between switches and routers. The IOS image you want to download and put on your 3620 routers(provided you want to stay on 12.2&7c)is c3620-is-mz.122-7c.bin, you must have a CCO login for cisco.com , but the URL for this file is:

http://www.cisco.com/cgi-bin/Softwa...=12.2&state=:HW:RL:SW&type=Limited Deployment

hope this helps..

by the way, to run the c3620-is-mz.122-7c.bin, your routers are going to require at least 48Mb RAM, and 16Mb of Flash

happy upgrading!

here is a quick fix. drop the vlan configurations on the 3550.

instead do the following

in place of vlan configuration on a certain port enable this command




no switchport


this will create a non switchport on the switch. it will function exactly like another routed interface which is exactly what a vlan is. the importance of vlan trunking only comes into play when you are trying to pass multiple vlans along the same connection or wire. for your practice i would configure the 3550 with the no switchport command.

after configuring that command on an interface you can issue the interface an ip address just like you would on any other router. its the same. worry about vlans when you go for your ccnp. understand them now and really learn them latter. you have a nice setup for a ccna student. good luck


get your subnetting down for the test

I just got back from a trip to the SE. I'll try these suggestions this evening when I get home. I'll post back when I can. Thanks.
