is there a way? 2500router 1900 switch and VLAN
Posted on 2003-03-15
First...I'm a student taking my ccna /ccnp and I have bit off more than I can chew!!! I have elected myself to proove to my prof that a Cisco 2500 Router and a 1900 switch can create 2 VLAN's on the same switch, routed through the single ethernet port ( using trunking and subinterfaces) on the 2500. I create the vlans on the switch we'll say 192.168.10.0 and 192.168.20.0 /24 for the vlans respectivly. On the router I know that i'm not supposed to assign e0 an ip address and assign e0.1 with one ip and e0.2 with the other. This is where im stuck....I'd like to use either 802.10 or ISL, which cisco says is supported on the 2500, but i cannot for the life of me find what command is used to encapsulate isl on the two interfaces on the router. I have found a bridge command and have found a way of adding the MAC addresses of the switch to BRIDGE 1, which I would assume I would then "bridge-group 1" on the interface e0.1 and e0.2. I know that the trunked link needs 100MB and the 2500 has only a 10MB connection, but there must be some way of acheiveing my routed VLAN on a single switch. Any help would be great ( even if it tells me I'm screwed ) and I appologise for the run-on paragraph.
