Hi,
A couple of months ago we bought a couple of ASR-1002Xs with 10X1GE-V2
cards on each one. Those cards are on slot 0/1
We were told by the pre-sales person to believe that those modules would
allow us to create an L2 tagged link between the two routers, behaving
similarly to a switch.
I found it a bit of strange initially, but we have some CGR 2010s with
GRWIC-D-ES-2s-8PCs
and that module basic allow us to establish a session to it and configure
it as if you were connected to a real switch. You can configure all ports
belonging to the module with switchport, spanning tree and all other L2
commands.
I thought the 10X1GE-V2 module would have the same behavior.
Well, yesterday I went to configure it and even after extensive researches
through Cisco documentation, it turns out that I couldn't find a way to set
it up as a pure tagged L2 port.
Our topology is something like:
+---+ +---+
|CE1| |CE2|
+---+ +---+
| Gi0/0/0 | Gi0/0/0
| |
| |
| |
| |
| |
| |
---------10.64.212.64/28---------
| |
| |
| |
| |
| |
| |
|Gi0/1/0 | Gi0/1/0
+----+ +----+
|ASR1|---------p2p---------|ASR2|
+----+ Gi0/1/5 Gi0/1/5 +----+
10.64.212.64/28 will be on OSPF area 0.
The entire subnet should communicate through the p2p link (Gi0/1/5
interfaces on each ASR).
>From what I could find, it's no possible to configure those ports as a pure
L2 port, so I'll probably have to use an l2vpn, L2 pseudowire or EVC
solutions instead.
My question is, is it possible to configure those modules as a pure L2
links or I'm missing something here?
I even have some "interface VLAN" commands available on the IOS, but they
report as invalid after I issue them.
Thanks,
Fabio
