Does the 76xx routers supports EoMPLS without SIP installed?

Unanswered Question

Dear Sir!

Can you tell to me, does the 7600 series of routers supports EoMPLS without shared port adapters (SPAs) and SPA interface processors (SIPs)?

I.e. if we have 7606S-RSP720C-R, WS-X6704-10GE ports connected to backbone and

WS-X6408A-GBIC with WS-X6148A-GE-TX ports connected to our DataCenter

(without any SIPs and SPAs installed on board).

Can we make EoMPLS for such clients, which are should connected

to our DataCenter through remote CAT3750-METRO?

Best regards,

Maxim

I have this problem too.

Hello,

we use C7600 with WS-X6748-SFP and WS-X6148A-GE-TX but without SIP/SPA.

The system supports EoMPLS in VLAN-mode (xconnect on subinterface).

Hello,

There are generally two modes of EoMPLS:

(1) PFC Based MPLS and related applications

mode

(2) WAN Based MPLS (SIP/SPA/OSM/ES20) and related applications mode

(1) Is only dependent on which Sup do you have

and generally works with most of the Ethernet (LAN) ports... If you have PFC-3B or later along with Sup-720, Sup-32 (which is PFC-3B) you can do it.

(1) Has some disadvantages - for example you cannot having L2 switching AND MPLS EoMPLS...

I.e. if you want to do local switching on Vlan 200 and part of the traffic to be switched part of the traffic to be EoMPLS you cannot do it without SIP/SPA/OSM/ES20

(2) In this case you need to check very well what you're looking for. These are expensive and they support MPLS and its Applications and even support VPLS, which is not possible with (1)....

I hope this answer your quesiton...

Please share some reference material on (2)WAN Based MPLS (SIP/SPA/OSM/ES20) and related applications mode.
