2.3 OSPF

- On Area 2223, with R7-BB2-BB3 on a broadcast network, in preceding task we prevent any layer2 BB2 to BB3 communication we must then be sure that R7 is the DR
-On R6 attached to multiple areas a virtual-link is needed to an area 0 router, even if others areas are connected to area 0.

3.1 BGP

This task is about distributing connected interface with minimal conf and appearing as IGP.
Network is a solution but doesn't use minimal conf :
redistribute connected with a route-map setting origin as igp

4.1 Inter-domain Multicast

Multiple PIM domains are interconnected via MSDP.
In order interdomain multicast work, I activated pim sparse-mode along the path between inter-domain.
Proctor didn't do that, He advertise the multicast sources on a BGP multicast adress family.

5.1 Filter PIM and BGP active-passive

I only used ACL to filter PIM and to force the way BGP is initiated between 2 routers. Other solution :
- ip pim neighbor-filter ACL
-router bgp xXX
neighbor x.x.x.x transport connection-mode passive

6.2 Netflow

Forgot the ip flow ingress on the interfaces.
