Thanks y’all, to be clear, are you saying “…VPLS. Segment Routing…” you view
those as fad technologies ? …or the opposite?
Yeah, I remember working for the US Navy in San Diego in 1999 and sitting in a
class taught be a vendor-provided SE, FORE Systems. The class was about, yep

The reason this particular customer wants to extend layer 2 is Vmotion.

the challenge is that when you tout your vm mobility play as “zero touch” after
move (i.e. you don’t have to re-ip your vm/application/etc to ensure 100%
business continuity) — you need to have stretched layer-2 between locations to
ensure proper functionality.
things like bgp host-route
The only reason for this is because some vendors do not want learn tcp/ip
just so they can force their own customer support on others. So they don't
want to deal with it and sell you on layer 2.

So I think (I could be wrong as I'm not a server guy) that all this L2
network emulation is because of server virtualization and moving vm's or
vmotion or something like that, and that they need to be in same ip subnet
(aka bcast domain) correct ?

Hi
I ended up dumping the OTV design for my customer as it was too expensive
to deploy. It's only supported on the 4451 (customer has been quoted for
4431) and needs and AppX license, was looking at £9000+ per router and
there is a built in 100Mb limit on OTV traffic. I'm doing VPLS now but was

This has been standard n7k operations since the platform
supported contexts.
Much like ASA — interfaces need to be dedicated to a context from the
management-plane perspective.
OTV requires a separate context due to inability to have SVI and OTV in same
context. OTV essentially becomes a part
Ha, thanks Justin, I just read the answer to my question I just posted...
OTV is cisco proprietary. Is OTV gaining steam in the industry as a
potential ietf standard ?
Interesting things you mention about assigning asics, and linecard
dependancies...

Thanks, so is OTV cisco proprietary ?

OTV is a Cisco proprietary protocol with some important design
considerations if you want to go in this direction. This includes
things such as

Hi Guys
I think I have the reason for the behavior in my lab. I have the 'silent
host' issue which happens in labs but generally doesn't happen in live
networks. For my host devices I used Cisco routers with an IP address on a
single interface, all these devices were doing is a ping and and ARP
Hi Guys
I have configured Multihomed OTV in a virtual lab on EVE-NG using Cisco
CSR's. The lab is 2 x CSR at one site both connected to layer2 switch and
a single CSR at a remote site.
Everything works good apart from one thing. At the dual router site, when
