6509E Switch support MPLS VPN

Unanswered Question
Aug 16th, 2009

Hi Friends,

I have a 6509 Swich with FWSM, 6724SFP, and 6748 Modules on it. As of now it is acting as the core swith of my network. I have a router at the perimeter connecting to the WAN. I have a new MPLS VPN link from the Telco now, since there is no free port on the router, can i connect this link to the Core Switch on any of the Line cards(6748 or 6724 module)

appreciate your valuable input



I have this problem too.

Hello Jacob,

yes you can because from your point of view it is a normal link the MPLS VPN is defined on the provider side.

to use a port as a routed port

int gix/y

no switchport

ip address x.y.z.k 255.255.l.n

(actually no switchport is the default on a C6500)

You may need to redistribute routes learned on the new link in a dynamic routing protocol

Hope to help

Hi guisee,

Thanks for the reply. In that case what is the VPN module on the 6509 switch?

thanks and regards

Hello Jacob,

a vpn module is used for IPSec based VPNs to perform encryption / decryption in hardware but it is a different type of VPN.

Hope to help
