Hamid, Don't know if you've already seen this, but check out http://www.cisco.com/warp/public/473/50.shtml#cisco2600 >From what I see on this page, it would appear that a FastEthernet port is required for interVLAN routing. BTW, group, I noticed in the configuration section of this page that there's this statement on the two switch interfaces being trunked: spanning-tree portfast I was told that PORTFAST disabled spanning-tree?? Have I been given bogus information or is this possible on the swtich model given (3512-XL)? >>> "Hamid" 08/22/01 01:28AM >>> Hi group, I was wondering if it is A MUST for the external routers's interface to be a 100Mb interface, is it possible to do the InterVlan routing on an ethernet port (10Mb) on a 2600 router? I tried to setup a simple scenario with my 2600 router in my home lab, setting the port connected to the 2600 router to TRUNK mode with isl encapsulation , and allowing all vlans. But when I tried to confgure the router's sub-interfaces I the following errors: Router3(config)#int ethernet 0/0.2 Router3(config-subif)#ip address 10.10.2.1 255.255.255.0 Configuring IP routing on a LAN subinterface is only allowed if that subinterface is already configured as part of an IEEE 802.10, IEEE 802.1Q, or ISL vLAN. The other problem was that inthe SUBIF configuration mode I didn't have the ENCAPSULATION command available.
