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 IP Tunnel Operational Vlan425 Yes (ldp) No Yes #sh run interface Vlan425 description TO-XXXX 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 -----Mensaje original----- De: cisco-nsp [mailto:cisco-nsp-boun...@puck.nether.net] En nombre de Ryan NSP Enviado el: martes, 20 de septiembre de 2016 04:24 p.m. Para: Tarko Tikan <ta...@lanparty.ee> CC: email@example.com 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. :) On Tue, Sep 20, 2016 at 4:02 PM, Tarko Tikan <ta...@lanparty.ee> wrote: > hey, > > If you don't want to spend any money on this, loop the related vlan > with external cable to physical port?
