ccnp lab question

[dev0cean]

Hi All,

Have 2 questions regarding lab setup.
1.I have 2 x 2900xl switches ( ver 12.0(5)WC7 ). I am trying to setup some trunking a vlans however when I use command vtp it comes up invalid. Does this IOS not support or maybe there is another reason why I cant ?

2. I have one 2513 (ver 11.0). I am trying to change router rid id for OSPF config. I know this is relatively new command so guessing I need IOS upgrade.

Thanks a lot

Late reply,

The only 2900Xl that supports trunking are those running the enterpise image. The SI doesnt support trunking, normally its the 4Mb versions run SI, the 8MB run EI. Check you are running the right IOS.

11.0 Doesnt support rid for OSPF, 11.3 Min required, but Id say (flash and Dram allowing) opt for a 12.2 JOS version.
Also remeber in version 11.0 a lot of the command sequenses are different, write t etc, ah the good old days!

To change VTP & VLAN Settings etc on the 2900XL you need to do this via the VLAN Database command, NOT from config (i.e. not conf t). Login to the switch and enter enable, then type 'vlan database' and press return. You can then change the VTP mode, add & delete VLANs etc. Any changes are not applied until you exit from VLAN database mode (with exit or <CTRL>C).

To dictate the RID on your router simply add a loopback interface. By default the OSPF process will choose its' RID from: Loopback interface with the Highest IP address, if no loopback interfaces exist (with IP addresses) then it will pick the highest IP address of a physical interface. Generally you would create loopback interfaces on your routers with /32 subnet masks and add these to the OSPF process:

interface loopback0
ip address 10.1.1.1 255.255.255.255
!
router ospf 10
network 10.1.1.1 0.0.0.0 area 0
