JN0-363 Exam Dumps : Service Provider Routing and Switching, Specialist (JNCIS-SP)

In OSPF, a totally stubby area does not permit type 3 summary LSAs (inter-area routes) or type 5 external LSAs (routes from outside the OSPF domain) to be flooded into the area. The area border router (ABR) will only send a default route as a type 3 LSA into the totally stubby area.

The flow label is a new field added to IPv6 headers that was not present in IPv4 headers. It is used to identify packets that require special handling by routers, particularly for quality-of-service (QoS) purposes.References:

The exhibit shows the configuration of a virtual switch calledsw-1with two VLANs defined within it:vlan_1with VLAN ID 1 andvlan_2with VLAN ID 2. To add interfacexe-1/0/5to the virtual switch, the interface must be associated with one of these VLANs. Since the interface is already configured withvlan-id 2, it implies that it is intended to be part ofvlan_2within the virtual switchsw-1. Therefore, the correct answer is to add interfacexe-1/0/5to thevlan_2bridge domain under thesw-1routing instance.
