Labs 9, 10, 11, and 12 done. INE Vol 1 - 2nd pass.

9- VRF Export Maps - basically using a route-map to classify a prefix/subnet and setting a extcommunity RT.

10- BGP SOO - Pretty similar to an Export Map but instead of setting RT in a route-map setting extcommunity SOO and applying the route-map to a bgp neighbor

11- OSPF Sham Links - Because OSPF will always prefer Intra area routes, when there's a backdoor link between 2 remote sites, the MPLS connectivity isn't used for the intersite communications unless a OSPF Sham link is created between the 2 PEs. Similar to a virtual link in syntax, just remember to advertise the Loopbacks your using to create the sham link into BGP (red connected) for reachability

12- OSPF and Domain-id - using individual processes on a per site basis and individual VRFs, you can still achieve site to site communications or restrict via a OSPF domain id and the proper import/export of route-targets.
