I have these concerns. Can someone explain why on 1.6 for R11 and R12 we need to un-shut the loopback?
Chinesedumps-Rxx(config-router-af)#af-interface lo0
Chinesedumps-Rxx(config-router-af)#no shut
For 1.9, how do we solve this requirement?
Ensure that the routes learned over eBGP sessions and further advertised in BGP will be considered reachable even if the networks on inter-as links are not advertised in OSPF. The configuration of this requirement must be completed exclusively within the "router bgp" context.
On requirement 1.12, does r24 need to shutdown the loopback in EIGRP? if yes, why?
