You can always hack it up and recirculate it and waste a couple front 
ports if you are really in a pinch :)

Trying to take back my sanity and collapse some multi-site vrf-lite, but

Hi, 

Yes, you can use a vlan has an MPLS uplink on a SUP720.
I use it all the time. Please take especial care on defining the appropriate 
MTU.

Here is the example that you are looking for:

#sh mpls interfaces 
Interface  IPTunnel   Operational
Vlan425Yes (ldp) No   Yes  

#sh run
interface Vlan425
 description TO-
 mtu 1546
 ip address x.x.x.x 255.255.255.252
 no ip redirects
 no ip unreachables
 no ip proxy-arp
tag-switching ip

interface GigabitEthernet1/5
 description SWITCH_STACK
 switchport
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 1,3,4,6,7,9-11,14-18,20-22,24-30,32-35,425
 switchport mode trunk  
 mtu 9216  
 no ip address


Sincerely,

Francisco

Asunto: Re: [c-nsp] MPLS via SVI on Sup720-PFC3b

Hey Tarko,

That might be less insane than vrf-lite'ing everything everywhere. I found some 
confusing documentation after doing some reading.

http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst6500/ios/15-1SY/config_guide/sup720/15_1_sy_swcg_720/vpn.html#50545

The note on that particular bookmark makes it look like it's possible.
"Note If you use a Layer 3 VLAN interface as the MPLS uplink through a Layer 2 
port peering with another MPLS device, then you can use another Layer 3 VLAN 
interface as the VRF interface."

Also this one (Pg. 32-5) for the PFC3.
http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst6500/ios/12-2SX/configuration/guide/book/pfc3mpls.pdf

"Configuration of MPLS switching is supported on VLAN interfaces with the mpls 
ip command."

This might be my lack of familiarity with MPLS on the whole showing, but if it 
helps with context, I don't need to 'xconnect' anything. Really all I am 
looking to do is MP-BGP between 2 data centers whilst exchanging routing 
information via the private VRF in each rather than connecting vrf-lites.
As I add sites it gets a little unwieldy.

Thanks for the guidance here. Slightly new territory for me... just want to 
make sure I'm properly articulating what I'm trying to pull off. :)

hey,

If you don't want to spend any money on this, loop the related vlan with 
external cable to physical port? Not pretty but you can get it done with 
zero cost if you have two ports to spare.

Hmm, thanks guys...

I would be OK tearing out and replacing with 2T to get this done if it
works.

That's not as bad as line cards galore. 6500s... so really don't want to
dump too much cash into them as I'm planning to get rid of them in the next
couple years.

Looks like if I do the 2T I also need to yank the gbic blade.

No.  Just port level.

2016-09-20 Thread Jason Lixfeld 
Nope.  You need a core facing 'ES' based card to do the label imposition with 
that Sup.

I believe the SUP2T is able to do this now without requiring core facing ES 
cards, but don’t hold me to that.

Howdy folks,

I am in the middle of some re-arch/migrations/you name it, and I am trying

Priorities/budgets/finite amount of hands and that...

Specifically I am trying to determine if I can run MPLS on a SVI off of a
Sup720-PFC3b with WS-X6748-GE-TX (CFC) line cards and a WS-X6516A-GBIC

level?
