[OSL | CCIE_RS] WB 8.0 Section 18 GRE Tunnels

[Lloyd Ardoin]

I am in the middle of section 18 in WB 8.0 and am having a problem I cannot seem to resolve between router 1 and router 2 running Rip v2. Based on the comments I should be seeing the 150.100.35.0 network in R2’s routing table but I am not. Per the instructions I have changed the primary and secondary addresses to make OSPF work and added the no validate-update-source under the Rip process on both R1 and R2 with the passive-interface command for the appropriate interfaces and neighbor statements. Once I add the passive-interface command under R1 along with the neighbor statement the 150.100.35.0 route will eventually time out on R2 and I am getting a message on R2 – (when I run debug ip rip events)   *Jul 23 22:26:06.443: RIP: sending v2 update to 150.100.36.1 via FastEthernet0/0 (150.100.36.2) - suppressing null update   which I cannot find any information on and may be irrelevant.   When you set up Rip v2 to unicast with the passive-interface and neighbor command should there be any type of output you can monitor in debug to watch for errors?   Can someone please help?     Thanks in advance,
