I'm facing a scenarion in which I have 2 sites connected with a L3 (a cloud - not p2p) connection between them.
The topology looks something like this:
VM server <--Lan--> C6500 <--LAN--> C3845 <--WAN--> C3845 <--LAN--> C4500 <--LAN--> Source IPT
The purpose of this is to monitor voice calls - which are in a separate vlan in the C4500.
I've searched the web for a solution, but all I came up with is ERSPAN which is not supported on C4500.
There's another solution with l2tpv3, but I think it is rather complicated for this secnario (many changes) - there must be something else... no?
Is it possible to accomplish L3 SPAN over a WAN to sniff the network?
Has anyone faced a situation like this?
Your feedback is highly apperciated,
Thanks for the help.
