Hey I am hope someone can shed some light as why I cannot get my intervlan routing working...

I have a 2620 router with a FA port broke into 2 subinterfaces with ISL encaped on both with correct colour.

I have a 2900XL switch with the VLAN database configured with 2 vlans Vlan 1 (managment) and VLAN 10

I cannot ping any intface on my second VLAN from VLAN1 bar the Trunk link interface on the 2620 router...

Please see the sh techs below...

I did make an error initally and configured two Managment Vlans via the "int vlan" command however I backed out with a "NO int vlan" This still shows in my running config but as shutdown.. could this be the problem?

Any help or pointers in the right direction would be greatly apprciated...

(I know the IOS is outdated however this shouldnt be a problem I think)
 
If you do a show vlan on the switch do both show active and applied to the ports you have in the config ?
 
On VLAN 10 I get act/lshut with fa0/22 and fa0/23s assigned to the vlan
 
here is exactly what I get:

VLAN Name Status Ports
---- -------------------------------- --------- -------------------------------
1 default active Fa0/1, Fa0/2, Fa0/3, Fa0/4,
Fa0/5, Fa0/6, Fa0/7, Fa0/8,
Fa0/9, Fa0/10, Fa0/11, Fa0/12,
Fa0/13, Fa0/14, Fa0/15, Fa0/16,
Fa0/17, Fa0/18, Fa0/19, Fa0/20,
Fa0/21
10 VLAN0010 act/lshut Fa0/22, Fa0/23
1002 fddi-default active
1003 token-ring-default active
1004 fddinet-default active
1005 trnet-default active
 
Cleared the config and working now.

I think the problem was due to the "Shutdown" managemnet VLANS...

Anyway
 
AutoTech,

Are you working on your CCNP BCMSN?

If so, what are you using for yoiur lab equipment?

Bob
 
the 2900 doesnt use ISL encapsulation, it only uses dot1q. if you had ISL on the router, then it wont communicate with the switch. try it with dot1q on the router.
Also, where is 10.111.1.1? that is your defualt route/gateway, but its not on the router. is it on another router?

Just to clear VLAN tagging support for Degg - 2900XL support both ISL and 802.1q, while newer 2950 support only 802.1q encapsulation.
