Good day all,


We have to migrate a router to PE but this router has one interface configure with x25 without ip address. Normally this router has to join another x25 router with x25/ip. How can we proceed to the configuration to bring x25 into the vrf ?

How to configure x25 over ip between PE-PE into Mpls vpn layer 3 ?



Any help 'll be really appreciated.


Best regards.


Stephane.

Hi,


mpls doesn't care about the traffic it carries.

So as long you can ping both routers, you XOT will be fine.


Hope this helps, please rate post if it does!

i agree with you about about the fact that the mpls don't care about the traffic it carries.


See the case below:

Suppose that R2 and R3 are PE, PE-PE are linked by mpls.x25 traffic goes througth vrf name TEST.


How can we perform this task ?



Best regards.

Hi,


As I was saying before, as long each PE router can ping the other, XOT traffic will be OK.
