Hello,

I am trying to set up a network for my local church, and i am having some issues and i hope someone can help me out.

here is my design,

10.147.209.0/24 for the wireless,
10.147.210.0/24 for the desktops.
10.147.211.0/24 for the servers

I plan on using the 2621 as the router, a 2950-12 for vlaning, and then 2950-24's for the end user connections.

I also have netscreen firewall to front end the entire build.

currently using f0/0 on the 2621 to connect to my 2950-12 subnet 10.147.212.0/24 using 3 subinterfaces, (the 2621 is the dhcp server.. for now)f0/1 is connected to my firewall, subnet 10.147.213.0/24.

on the 2950-12 i am using ports 1 and 2 for subnet 209, ports 3,4,5,6,7,8 for subnet 210, ports 9,10,11 for subnet 211 and port 12 for the uplink to f0/0 on the 2621. I am going to be connecting 2950-12's to the interfaces on the 2950-12, to provide my enduser connectivity.

and now for my issues.

I can't get the 2621 to route packets between f0/0 and f0/1 i can ping (from subnet 210) to the interface ip 10.147.213.1 but i cant it the firewall at 10.147.213.2

also i need to do some traffic shaping ( that i have yet to start) so that subnet 209 and 210 share 5 mbs and subnet 211 gets 10mbs. (I have a 15mbs pipe).

can someone please look at my configs below, i am hoping that someone can figure out why i cannot route between the 2 interfaces on the 2621. also if you wouldnt mind looking over my configs and seeing what i missed that would be great.

Thanks in advance for everything,
Brad

Yes, I think the 2950 will defualt to ISL as the Trunking protocol, so you should specify "switchport tr en dot1q" on f0/12.

Also, make sure you have added in routes on your firewall pointing subnets 209, 210, 211, 212 to the router.
You can summarise 209, 201, 211 as 208.0/22 if you don't mind 208 being included.
 
1) move the config off of the main f0/0 interface and onto a subinterface
2) the default route is pointing to vlan1 svi on the 2950 switch as opposed to the firewall
3) as vince said, make sure the routes are in the firewall for the return traffic
4) update the IOS to something more recent than 12.1
5) if you want to shape traffic do something like this:
Code:
access-list 101 permit 10.147.209.0 0.0.0.255 any
access-list 101 permit 10.147.210.0 0.0.0.255 any

class-map shape-209-210
  match access-group 101

policy-map SHAPE_TRAFFIC
  class shape-209-210
    shape average 5000000

int f0/1
 service-policy output SHAPE_TRAFFIC

I hate all Uppercase... I don't want my groups to seem angry at me all the time! =)

Think Unclrico has indicated what needs to be done . All addressing on the trunk link should be under the subinterface . Remove the default gateway command , it doesn't do anything if routing is turned on . The 2950 only supports dot1q so ISL is out of the mix.
 
Thanks Very much, all is working now.
