Include connected networks in L3VPN/VRF

‎07-19-2011 09:38 AM

Hello,

 

I'm trying to set up a VRF/L3VPN where I don't have a CE-Router. Attached to the PE-Router is a switch which directly hold customer equipment.

 

I understand that juniper per default does not include directly connected networks in the VRF (because that would mean 2 lookups for the destination).

 

I'm using Juniper MX Trio with MPC Cards and as I see it, I could use "vrf-table-label" or use a vt- Interface.

 

I found..

 

http://www.juniper.net/techpubs/en_US/junos11.1/topics/usage-guidelines/vpns-filtering-packets-in-la...

 

...which does not list the MX series in the compatibility section.

 

"vrf-table-label" has a few drawbacks and I'm unsure if there are better ways. Is there a best practice or some advice regarding this? Should I use a vt- interface (would that even work when I only have MPC cards?)

 

Regards

 

Sebastian

I would use vrf-table-label.  It's pretty simple to use.

 

To use the vt- interface you will need to configure a tunnel interface on one of the Trio PFE's, then you can use the vt- interface. NOTE: You do not lose the use of that port like on DPCE's
