xconnect using L2TPv3

R1 is running RIPv2.

R6 is also running RIPv2.

There are bunch of routers between R1 and R6 running OSPF or whatever
routing protocol that turns you on.

I want R6 to get all R1 s RIP routes.

Do not use redistribution, AToM, IPnIP or GRE tunnels to accomplish this.
Come up with 2 solutions. Common unicast me the solution..

 

 

Narbik,

I was under the impression from what i have read that L2TPv3 does not require Multiprotocol Label Switching to function, and I just labbed up a simple session with no MPLS running on the backbone and the L2TPv3 was able to pass traffic across IP backbone and passed the RIP routes over the L2TPv3 tunnel

what am i missing that is not AToM, no MPLS in play right?

R1 <-> R2 <-> R3 <-> R6

R1#sh ip int br
