| Cheers. You are the 3rd person to confirm this and I believe the requirements are:
2500 Router with...
16MB NVRAM/DRAM...
IOS v12.1 > with IP Plus...
Just in case anyone else wants to try it/know. | |

| I'm not sure where this thread came from, but intervlan routing is not allowed on a 10mbs ethernet port... | |

| I think he posted new thread rather then replying.
Interesting what you say - have you ever tried it with IP plus??
I have and am pretty certain it works, after testing it on yeti's online labs.
Also the following link from Cisco's website clearly states ethernet for 802.1q and fast ethernet for ISL.
http://www.cisco.com/warp/public/cc...78_pp.htm#16764
The Cisco IOS Software offers the industry's most comprehensive VLAN services, supporting multiple VLAN protocols optimized for different media—Cisco's Inter-Switch Link (ISL) for Fast/Gigabit Ethernet, IEEE 802.10 for Fiber Distributed Data Interface (FDDI) backbones, and via LAN Emulation over ATM. Software Release 12.0T adds support for the IEEE 802.1Q VLAN standard such that the IOS software is able to perform full-feature routing of 802.1Q-tagged IP and Novell Internetwork Packet Exchange (IPX) VLAN traffic on Ethernet media. | |

| I have a couple 2501's setup in my home lab. I'll try to set this up over the week end. I guess my next next question is what port will you use on a Catalyst switch as your trunk? I thought the 1900, 2900. 3500, 5500 series switches will only let you set up a ISL trunk on the Fast Ethernet Port. I have a 3com SuperStack 1000 that allows a 10mbs trunk. May be that is what Cisco intentions were when they set that up to encap with 802.1q. I'll let you know what I find out.... | |

| It'd really save my bacon if you get it working!!
Several times I have stated that you can do 802.1q with a 10 Meg Ethernet port - hands up it appears I'm mistaken (humble pie and all that!).
I've double checked what I am saying and can't get it to work, even with enterprise plus. I must have been using one of the 2600's in the lab. As for 3Com, I was also using one of these at the same time so can say with some confidence that I was definately using dot1q.
Apologies if anybody else has gone out and brought 2500's on my say so - somebody prove me wrong please.
Now who else can I mislead................ |
